SPLINES AND SERRATIONSA splined shaft is one having a series of parallel keys formed integrally with the shaft and mating with corresponding grooves cut in a hub or fitting; this arrangement is in contrast to a shaft having a series of keys or feathers fitted into slots cut into the shaft. The latter construction weakens the shaft to a considerable degree because of the slots cut into it and consequently, reduces its torque-transmitting capacity.花键轴是一种具有“一系列相互平行的齿、并且齿与轴整体成型”的轴，它与在轮毂上或者装配体上开的键槽相配合。

这种装置与“在轴上开槽并且与一组销子或者楔键相配合”的结构相反。

后者的结构由于在轴上开槽大大降低了轴（的强度），降低了传递扭矩的能力。

Splined shafts are most generally used in three types of applications: 1 ) for coupling shafts when relatively heavy torques are to be transmitted without slippage; 2) for transmitting power to slidably-mounted or permanently-fixed gears, pulleys, and other rotating members; and 3) for attaching parts that may require removal for indexing or change in angular position.花键轴主要用在以下三种情况：1）需要在无滑动的联轴器上传递大的扭矩；2）用于向“可滑动的装配组件”或者“固定装配的齿轮组或滑轮副”传递动力，3）用于“要求指定滑移量或转角位置”的配件上。

标准件英文Standard Parts。

Introduction。

Standard parts, also known as standardized parts, refer to a category of components that are widely used in various mechanical products. They are essential for the assembly and production of machinery, equipment, and other industrial products. Standard parts play a crucial role in ensuring the interchangeability, reliability, and efficiency of mechanical systems. In this document, we will delve into the concept of standard parts, their significance, and their various types.Significance of Standard Parts。

The use of standard parts offers several advantages in the design and manufacturing of mechanical products. Firstly, standard parts simplify the design process by providing a range of pre-designed components that can be readily incorporated into a product. This not only saves time but also reduces design complexity and cost. Secondly, standard parts facilitate interchangeability, allowing for easy replacement and maintenance of components. This is particularly important in the case of repairs and upgrades. Thirdly, standard parts contribute to the overall quality and reliability of a product by ensuring consistent performance and compatibility. Lastly, standard parts enable economies of scale in production, as they can be mass-produced and stocked, leading to cost savings for manufacturers.Types of Standard Parts。

R+W torque limiters are delivered ready for installation. After incoming inspection, the coupling should be stored in its original packaging until ready for installation. A copy of this installation and operating manual should be kept with the coupling.T ransportRotating couplings can be very dangerous. Proper guard-ing should be in place at all times and is the responsibilityof the machine builder, user, or operator. Do not approach or touch a coupling while it is rotating. Make sure the ma-chine is …locked out“ and be accidentally started during installation or maintenance of the coupling.Please carefully and completely read the following installation, opera-tion and maintenance procedures for the R+W torque limiters. Failureto comply with these procedures may result in poor performance and/or failure of the torque limiter.Installation of the torque limiters should be perfor-med by a qualifi ed technician.Safety alertAccording to EG guidelines for machinery 2006/42/EG, Appendix IIB As per machinery guidelines (MR), shaft couplings are not considered ma-chines, but rather components for installation in a machine. Their putting into operation is subject to the fulfi llment of all requirements of machinery regulations by or after integration into the fi nal product.Manufacturer‘s declarationGeneral function of the torque limiter Single / Multi-Position Automatic Re-engagement■Torque is transmitted through hardened ball bearings (4) arrangedaround the coupling‘s circumference and loaded into conical detents (5).■ The ball bearings are loaded into the detents by an actuation ring (3) which, in turn, is held in place by disc springs (2).■ The disengagement torque is continuously adjustable through rotation of the adjustment nut (1).■In the event of an overload, the actuation ring (3) moves toward the disc springs (2) which are pushed over center by the force from the balls (4) exiting their detents. This completely separates the driving and driven sides of the coupling.■ As a consequence of the actuation ring‘s (3) axial movement, the mechanical limit switch or proximity sensor (6) is activated, signaling the drive to be shut down.Positive stopActuation path (see table 5)engageddisengaged R+W torque limiters are preset and marked with the desired disengagement torque setting at the factory. The min. and max. of the torque adjustment range (10) are also marked on the adjustment nut (1). The disengagement torque is continuously adjustable within the prest range (10) by turning the adjustment nut, increasing or descreasing the tension on the disc springs (2).Caution! The torque limiter should not be adjusted outside of the preset torque adjustment range. After loosening the clamping screw (11) (max. 1/2 turn), the adjustment nut can be rotated with an appropriate tool (e.g. R+W spanner wrench). After adjustment, tighten the clamping screw. The torque limiter can now be used.(see table 5)Clamping screw ISO 4762R+W spanner wrench(see table 5)MarkingAdjustment nut with inscriptionMarkingAdjustment range inscriptionmin.max.30 N m 50 N m 80 N mm i n .m a x .R+W 66/5ቫ Adjustment range ቭ Clamping screw RAll mounting surfaces including shafts, bores, keys, and keyways must be clean and free of burrs, nicks, or dents. Inspect shaft diameters, coupling bore diameters, and dimensions and tolerances of keys and keyways prior to installation. All R+W coupling bores are machined to ISO tolerance H7. The overall clearance between shaft and hub should be between 0.01 abd 0.04 mm. A light coating of machine oil is recommended to ease the mounting process and will not affect the clapming force of the hub.Caution!Oils and greases containing molybdenum disulphide or other high pressure additives should not be used.Dismounting:Remove the axial fasteningmechanism and slide the cou-pling off the shaft with theappropriate tools.Mounting:Using the appropriate tools, slide the complete cou-pling onto the shaft end. The final position must besecured axially, e.g. with a washer (12).SLPFunction of metal bellowsR+W metal bellows couplings are flexible shaft couplings.The highly flexible, torsionally rigid stainless steel bellows provides backlash free transmission of torque. The metal bellows compensates for lateral, axial and angular misalignment, with very low restoring forces.Mounting instructions SL2 (with integral bellows coupling)KeyShaft endWasherClamping screw RTable 5 / Page 4The elastomer insert is the compensating element in an SLE coupling. It trans-mits torque without backlash and damps shock and vibration. The SLE cou-pling‘s elastomer insert determines the hysteresis characteristics of the entirerotational axis, and is available in two different designs.When the coupling hubs are pushed together during installation, axial force isrequired to overcome the elastomer insert‘s preload tension. The amount offorce required can be reduced by cleaning the elastomer insert and then apply-ing a coat of light oil to its contact surfaces.A / 98 Sh A red TPU-30°C - +100°C high dampingB / 64 Sh D green TPU-30°C - +120°C high torsional stiffnessClearance for axialoffsetapprox. 2 mmElastomer insertHubHubContact surfacesMounting forceMaximum shaft misalignmentCaution! Precise alignment of the R+W torque limiters greatlyincreases their service life.Maximum misalignment values can be found in tables 3 and 4.Reducing or eliminating lateral misalignment lessens the radial load-ing of adjacent bearings, increasing the performance of the drive train.For high speed drive systems, precise alignmnet with a dial indicator isrecommended.Table 2R+W Antriebselemente GmbH Alexander-Wiegand-Str. 8 · 63911 KlingenbergPhone +49 (0) 93 72 - 98 64-0 · Fax +49 (0) 93 72 - 98 64 20*********************·www.rw-kupplungen.deThe above mentioned information is based on our present knowledge and ex-perience and does not free the user from regular inspection. A legally binding guarantee, in regards to third party protection rights, is not given.597/10/11/2.000The plunger should be placed as close as possible to the actuation ring of the torque limiter (approx. 0.1 - 0.2 mm).Mechanical limit switchOrder No.: 618.6740.644Ø 4.2Caution:After installation, it is necessary to fully test the functionality of the mechanical limit switch.Additional informationRotational speed:The service life of the torque limiters depends on the rotational speed at which the torque limiter disengag-es, as well as the frequency and duration of disengage-ment events.Wear:No wear occurs while the cou-pling is engaged. In the event of an overload, the drive must be shut down immediately through the use of a mechanical limit switch or proximity sensor.Maintenance:Since the torque limiters are not subject to wear while engaged, there is no required mainte-nance. The positive locking con-nections are backlash free and the unit is lubricated for life.Selection:Torque limiters are typically selected based on the required disengagement torque value. This value must be greater than the required torque for normal acceleration and deceleration of the machine.The torque limiter´s disengagement torque is typically determined by the data from the drive, motor, and/or gearbox.。

Basic Concept in MechanicsThe branch of scientific analysis which deals with motions 对运动、时间和作用力进行科学分析的分支称为力学 它由静力学和动力学俩部分组成。

静力学对静止系统进行分析 即在其中不考虑时间这个因素 动力学对随时间而变化的系统进行分析。

Forces are transmitted into machine members through mating surfaces 力通过接触表面传到机器中的各构件上。

例如 从齿轮传到轴或者从齿轮通过与其啮合的轮齿传到另一个齿轮 从V带传到带轮,或者从凸轮传到从动件。

由于很多原因 人们必须知道这些力的大小。

这些力在边界或在接触表面的分布必须合理,它们的大小必须在构成配合表面的材料的工作极限以内。

例如 如果作用在一个滑动轴承上的力太大,它就会将油膜挤出,造成金属与金属的直接接触,产生过热和使轴承快速失效。

如果齿轮相啮合的齿与齿之间的力过大 就会将油膜从齿间挤压出来。

这会造成金属表层的碎裂和剥落,噪音增大,运动不精确直至报废。

在力学研究中,我们主要关心力的大小、方向和作用点。

Some of the terms used in mechanics are defined 在力学中要用到的一些术语定义如下。

Force Our earliest ideas concerning forces arose because of our desire to push ,力关于力的最早概念是由我们需要推、举或拉各种物体而产生的。

因此，力是物体之间的相互作用。

力的直接概念包括作用点、大小和方向，这些被称为力的要素。

Mass is a measure of the quantity of matter that a body or an object contains . T质量是物体内所包含的物质的量。

PAY OFF REELFunction- To transfer strip to the welder with automatic centering.- To ensure continuous strip unwinding to the line under regulated tension.DescriptionThe pay off reel mainly includes :- an expansible mandrel,- a gear box,- a mobile frame supporting the gear box and drive unit,- a stationary frame.- a stripper plateThe mandrel is made of the following elements :- a sleeve in special iron GGG 70- 4 segments in nitrided steel (superficial hardness 500 to 600 HV5, on a depth of 0,3 mm minimum)- Wear plates in 42 Cr Mo 4, nitrided- Each segment includes 5 wedges- Mandrel shaft made of 30 Cr Ni Mo 4 (90/105 kg/mm²)- Central expansion rod connected to a rotating expansion cylinder- Linear transducer mounted on the mandrel, for purpose of precise measure of actual inner coil diameter- 2 conical bearings are mounted at mandrel end for the mandrel nose - Grease lubrication, by hand pump without any dismounting.The gear box is manufactured with a horizontal joint and includes 2 stages of gears.The frame is made of welded and machined steel.Gears are of helical type, made of steel treated at 100 kg/mm². Gearings and bearings calculated for a service life of 50.000 hours at maximum speed and load. The bearings of mandrel shaft are selected in order to have a zero play.The mobile frame is of machined welded steel. It moves on the staticframe through a hydraulic cylinder.The static frame is of welded steel design, anchored to foundation.A system of machined ways (one flat, one V-shaped) and counter slides provided with bronze wear plates.The stripper plate includes a pushing plate actuated by hydraulic cylinder. In an out movement guided by 2 rods moving in bushings mounted on the housing of the gearbox.Still stand disc brake between motor and gearbox actuated by electro-pneumatic brake.2. ENTRY SHEARFunctionTo cut off the unconforming head and tail of the coils. Shear actuation controlled by PLC of entry section, based on:- overthickness information coming from level 2- entry thickness gauges if implemented in the future.Description“Start-stop” upcut shear of guillotine type, cuts strip when stopped by means of a pinch roll pneumatically pressed and a spring loaded clamping device.- The upper blade is fixed; the lower blade is movable and actuated by hydraulic cylinder, articulated rod and double levers in V.A special pin is provided to avoid any shearing operation during the maintenance periods.Blades are in special steel x 100CrMoV51; each has four cutting edges for low maintenance and long life. The moveable blade has a slight slope, and the fixed one is straight.The moving holder slides in machined ways on the shear side frame. These ways are lined with replacement brass wear plates.- The rigid frame is of fabricated welded design. Guides and supports are mounted so as to avoid hurting of the26ends during feeding and contact with blades while running. - Just before the shear blades, a low pinch roll unit is mounted, actuated by 2 pneumatic cylinders with rack and pinion system for synchronisation. Top roll is fixed and driven by hydraulic motor, the bottom roll is moveable and idle. The purpose of this pinch roll is to clamp the strip during cutting sequence, to thread the front end of strip into the shear, and to discharge the last crop end.A photocell in combination with a pulse generator signal, ensures that the latter is long enough (to avoid the falling of small residual pieces in the machine).Note:The shear item 168, at bottom pass line, includes a second pinch roll unit, identical to the pinch roll here above, and mounted on the frame of the shear, at exit side. The purpose of this additional item is to deliver the scrap pieces onto the conveyor dedicated to the removal of scraps in cross direction at bottom pass line (see item 172).- For purpose of easy maintenance, the N° 1 and N° 2 shear housings are mounted on slides; with this system, the two superposed shears can be transferred off line by an auxiliary manual hoist.- The gap between the blades is adjusted manually by a screw system.273. WelderCarriageThe carriage will be moved by means of AC-servo motor of changeable speed through ball screw.The carriage will move at right angles with the strip, supported by guide ways which are fitted to the main base.A shearing mechanism, welding electrode mechanism, welding transformer, etc. are incorporated in the carriage. The carriage will conduct welding by moving to driving side (DS).Shearing unitThe welding machine has a double cut shear available for simultaneous cut of leading and trailing coils having been clamped to make correct lapping of the both ends of leading and trailing strips. The relationship between upper and lower parts can be located correctly by means of the guide pins.Electrode headsThe upper and lower electrode heads are composed of an electrode housing of copper alloy ,and electrode shaft subjected to internal water cooling effect, electrode wheel, bushes, caps, etc. They are available for easy conversion of electrode wheel.The changing time for complete electrode assembly:3 min per one piece under normal condition.Clamping unit28A beam-type clamping unit will be equipped on the entry and exit sides of the main base.The entry clamp will clamp trailing coils, move in the line direction after sheared, and lap both ends of the strips. When the entry clamp moves for lapping, the exit clamp will incline the leading coil so that the both ends of the coils may not come in contact with it.4. FURNACE GENERAL DISPOSITIONThe proposed furnace is of the vertical continuous annealing type suitable for processing strip to automotive quality.The main characteristics of the proposed equipment are: - A preheating section able to heat up the strip by recovering heat in the exhaustgases of the heating section. The advantages of the preheat section are:- the preheating section will provide an energy saving of approximately 7 to 8%on the gas consumption.- the strip temperature at the exit of the preheat section will be around 180 to200°C and the thermal shocks on the first deflector rolls of the heating sectionwill be decreased. This is very favorable for the life time of the rolls and the29strip tracking.- the strip is heated by blowing hot atmosphere gases on the strip, providing an efficient cleaning of the surface.- A multipurpose heating section provided with complete radiant tube heating capacity. This arrangement is the most suitable to the actual requirements for the following reasons:- in combination with the preceding electrolytic cleaning section, it guaranteesthe zinc adherence in continuous and transient operations. - the moderate furnace temperature in the radiant tube heating section will guarantee the absence of any adverse effects on the thin strip during line stops and transient operations.- heat recovery of the strip’s energy consumption is the maximum possible andthe final hot water production is in accordance with the technical requirements of the cleaning section.- maximum flexibility of operation is achieved by the use of light internal insulation and the homogeneous conception of the furnace.- A slow cooling section before the rapid cooling section. - A rapid cooling section of type XSQ able to provide a cooling rate of 45°C/s for DP and TRIP material of 2.3 mm thickness and deliver to the equalising section a strip with uniform transverse temperature.30- A holding section able to hold and equalise the strip temperature and to provide a buffer area between the coating section and the rapid cooling section.- An exit section incorporating a bridle roll set suitable to deliver into the zinc pot a strip under high tension necessary to provide stability through the zinc wiping system.- Mobile and fixed electrically heated galvanneal soaking sections.- A cold-air after-pot cooling section.- A pair of water cooled deflector rolls at the top of the tower.- A final air-cooling section to decrease the temperature before the water tank.- A water-cooling section including spray quench tank, wringer rolls and dryer.5. CERAMIC COATING POTPot-1 pot of arc-welded steel sheet and sections with 2 connecting flanges for the inductors;-Bath level control device by laser (see item 13);cable track-thermocouple, one in operation and one in back-up .
