气压传动是风动技术与液压技术演变、发展而来。

气压传动是以压缩空气作为工作介质传递运动和动力。

由于气压传动的动力传递介质是取之不尽的空气，所以污染小，因此在自动化领域中具有广阔的发展前景。

气压传动广泛应用于纺织、机械、汽车、电子、军事、钢铁、化工、食品、包装等行业中。

随着原子能、空间技术、计算机技术等的发展，气压传动技术必将更加广泛地应用于各个工业领域。

气动板手（Impact wrench），也称为是棘轮板手及电动工具总合体，主要提供高扭矩输出最小的消耗的工具。

压缩空气是最常见的动力源，尽管电动或液压动力也使用。

气动板手被广泛应用在许多行业，如汽车修理，重型设备维修，产品装配（通常称为“脉冲工具”和专为精确的扭矩输出），重大建设项目，以及其他任何一个地方的高扭矩输出需要。

气动板手可在每一个标准的棘轮插座驱动器大小，从小型的1 / 4“驱动器的工具小组装和拆卸，到3.5 ”都有。

气动扳手是用气压推动叶片，压力能转化为扳手内轴的机械能。

紧固强度通过设置气压的大小来设置。

比较形象的比喻就是把电风扇反过来使用就是气动扳手。

气动扳手的扭矩值是以改变气压的大小来控制的，且没有精度，而是以重复度表示。

但若在气动扳手上加装气动扳手专用的传感器，则可用精度表示。

现今主要流行的气动扳手有双转速型式等其主要特点是：∙基于传统的气动扭力扳手,标准系列的气动扳手是经过40年的经验累积下来的成果,也达成到今日工业的要求.∙应用于全世界上千种场合,气动扭力扳手持续展现着NORBAR大扭力工个范围的根基.∙此型式适合于各种有螺丝的应用.∙正反转操作.∙静音、非冲击式可降低操作者的疲劳.∙扭力重复度+/-5%.∙各式各样的反作用力臂型式可供各种工作场合搭配使用.┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊1 总体方案设计1.1参数要求（1）最大扭矩： 6公斤.米（2）无负荷转速： 4000转/分（3）工作气压： 4~6公斤/厘米1.2 整体结构概述机电一体化机械系统是由计算机信息网络协调与控制，用于完成包括机械力，运动和能量流等动力学任务的机械和机电部件相互联系的系统。

3. 使用者应根据各种不同气动工具的需求，选择不同规格的空气压缩机。

4. 开始操作气动扳手之前应先将管路中的水气与予吹除干净。

如此，当可避免残留在压缩空气中的水分或灰尘进入气动扳手内部，以免影响气动扳手的正常性能，甚至造成损坏。

三、理想的管路按装方式：空压管径与长度需求：1.连结气动扳手的空压软管⑩之管径∮A清楚标示于下页规格表当中，请参照使用。

2.连接主管路及空压软管的岐管（从⑦到⑨），其管径∮B最少必须是空压软管∮A的两倍。

3.主管路（从①到⑧）的管径∮C应为空压软管∮A的三倍。

4.连接气动扳手的空压软管其长度不得短于15英尺（4.5米以上）。

四、作业注意事项：1. 气动扳手完全采用压缩空气来加以驱动，仅限以手动方式进行操作。

因气动扳手并不具备绝缘效果，故，使用时应特别注意不可接近电源。

2. 气动扳手是专为固定或松脱螺丝钉或螺帽而设计的气动工具，任何不同于上述使用时应特别注意不可接近电源。

3. 限使用气动扳手套筒及零配件，严禁使用气动工具的套筒或零配件。

4. 高分贝的噪音可能会使听力受损。

故，当使用气动扳手时请务必戴上防护耳罩。

Other PTM & PTME internal control toolswith minor variances are also covered.Description of options:3SAFETYIMPORTANT:DO NOT OPERATE THE TOOL BEFORE READING THESE INSTRUCTIONS. FAILURE TO DO SO MAY RESULT IN PERSONAL INJURY OR DAMAGE TO THE TOOL.This tool is intended for use with threaded fasteners.The use of ear protectors is recommended.Do not use these tools in potentially explosive atmosphere as they contain grease, which may cause an explosion hazard in the presence of pure oxygen. These tools also contain aluminium alloy components which may cause a hazard in certain explosive environments.Unexpected tool movement due to reaction forces or breakage of drive square or reaction bar may cause injuries.Isolate the tool from all energy sources before changing or adjusting the drive square or socket. There is a risk of crushing between the reaction bar and work piece. Keep hands away from reaction bar. Keep hands away from tool output.Keep loose clothing, hair, etc. from being caught in any rotating part of the tool.These tools require a reaction bar. See section on Torque Reaction.Ensure all hoses are correctly fitted before switching on the air supply. This avoids the risk of injury by whipping air hoses.Unexpected direction of drive square movement can cause a hazardous situation.Use only sockets and adaptors which are in good condition and are intended for use with power tools.PneuTorque ®Wrenches are non-impacting, torque controlled threaded fastener tightening tools and must always be operated with the following:∙ Clean dry air supply with a minimum flow of 19 litres/sec (40 CFM).∙ Lubro Control Unit or similar Filter, Regulator and Lubricator Unit 1/2” Bore (12 mm). ∙ Impact or high quality sockets. ∙Reaction bar.4 INTRODUCTIONThe PneuTorque ®PTM & PTME Internal Control (IC) tools are air driven power tools designed for applying torque to threaded fasteners. A target torque or angle value is set on the tool, when the measured torque or angle reaches this target the tool’s control system shuts off the air supply for accurate and repeatable torque application. There are models to cover torque capacities of 500 N·m to 2000 N·m.Parts IncludedDisposalThis symbol indicates that the product must not be disposed of in the general waste. Please dispose of according to your local recycling laws and regulations.Contact your distributor or see the Norbar web site () for further recycling information.AccessoriesNOTE 1: Requires both ‘Reaction Plate’ and ‘Reaction Adaptor’ to be used together.5FEATURES AND FUNCTIONSTwin MotorThe tools use two motors; motor 1 to quickly run-down the fastener and motor 2 to achieve final torque.Torque TransducerAll tools are fitted with a torque transducer, the transducer forms part of the tool and cannot be removed. The applied torque is accurately shown on the display in Newton metres (N·m) or pound force feet (lbf·ft.). The display captures the peak torque and holds this value for an operator defined time before resetting.Angle MeasurementThe tool can be fitted with an angle sensor. The applied clockwise angle is then accurately shown on the display in degrees of rotation from an operator defined torque value. The display captures the peak angle and holds this value for an operator defined time before resetting. Angle measurement is accurate in the clockwise direction only. The angle measurement can be switched off when not required.TriggerThe trigger controls the flow of air. The more the trigger is pressed the more air flows into the tool. This allows for slow positioning of socket and reaction bar. Once positioning is complete, the trigger must be fully pressed for correct torque application.Clockwise / Counter-Clockwise SelectorTools can tighten and release both clockwise & counter-clockwise threaded fasteners. Angle measurement is accurate in the clockwise direction only.Reaction BarThe reaction bar ensures all reaction forces are contained, so that torque reaction is not passed back to the operator. Several reaction bar types are available, including the PTME / Nose Extension reaction. The PTME / Nose Extension are for use where tool access is restricted including applications on heavy vehicle wheel nuts.Non-ImpactingLow vibration levels make these tools comfortable and safe for the operator to use. In addition there is less damage to the tool, socket and threaded assembly.Replaceable Drive SquareTo avoid internal damage to the tool (especially due to torque overload), the output drive square has been designed to shear first. PneuTorque® tools are fitted with a drive square that can easily be replaced; alternative drive square sizes may be available.HangerThe hanger can be used to suspend the PneuTorque® from a balancer.67SET UP INSTRUCTIONSThe PneuTorque ®set up covers the following items:1. PneuTorque ®Hanger 2. Connecting Air Supply 3. Connecting Electric Supply 4. Air Lubrication 5. Torque Reaction6. Clockwise / Counter-Clockwise7. Setting Shut-Off Torque/ AnglePlease complete the set up in the order shown.PneuTorque ® HangerThe PneuTorque ®hanger (Figure 1-E) is designed to be used with a suitable balancer to provided comfortable tool use. Remove hanger if not required.Connecting Air SupplyWARNING:TO AVOID HAZARD FROM WHIPPING AIR HOSES MAKE ALLCONNECTIONS TO THE TOOL BEFORE TURNING ON THE AIR SUPPLY.Make sure all hoses are clean, in good condition and free from dirt / water.Connect the tool air inlet hose (Figure 1-C) to the outlet side of the lubro control unit (Figure 1-B) (not supplied), observing air flow direction arrows.TIP: On tools supplied with quick air couplings, fit the coupling plugto the tool inlet and the coupling socket to air hose.To connect, push couplings together.To disconnect, pull back lock on socket coupling.Connect the inlet side of the lubro control unit (Figure 1-B) to the air supply (Figure 1-A) using a minimum hose size of 1/2” bore (12mm). Avoid using 1/2” bore hoses of longer than 5 meters from the supply to the pressure regulator unit as this will reduce the performance of the tool.Turn on air supply and check for air leaks.FIGURE 1 – ConnectionsA BC D EFG8 Connecting Electricity SupplyAttach the power supply extension lead between the power tool lead (Figure 1-F) and the power supply (Figure 1-G).Fit the mains power lead to the power supply (Figure 1-G). The display and LED’s will illuminate for a short time.TIP: If the power lead has no plug fitted, wire as follows:BROWN-LIVE BLUE-NEUTRAL GREEN / YELLOW-EARTHAir LubricationThe tool must be used with oil lubrication in the supplied air, this is achieved by using a Lubro Control Unit (not supplied).Set the air lubrication:a. Fill Lubro Control Unit with hydraulic oil (Shell Tellus S2M 32 or equivalent good quality hydraulic oil).b. Ensure the tool drive square is free to rotate.c. Run the tool by pressing the trigger.d. Adjust the Lubro Control Unit for maximum tool air pressure. Air pressureis shown on the gauge.TIP:Using maximum air pressure will give maximum tool speed.e. Adjust Lubro Control Unit to supply 6 drops of oil per minute.f. Release trigger.IMPORTANT:THE WRENCH MUST BE FREE RUNNING WHILE ADJUSTING THE AIR PRESSURE TO GIVE THE CORRECT SETTING.See Lubro Control Unit handbook for more details.Torque ReactionThe reaction bar ensures all reaction forces are contained, so torque reaction is not passed back to the operator. Several reaction bar types are available.Fit reaction bar as detailed below: Factory fitted, not removable.9It is essential the reaction bar rests squarely against a solid object or surface adjacent to the fastener to be tightened. The contact area must be within the shaded area of figure 2, with the contact area as large as possible.FIGURE 2 – Safe reaction windowWARNING: CARE MUST BE TAKEN TO ENSURE THAT THE REACTION BAR IS ONLYUSED WITHIN THE LIMITATIONS SHOWN IN FIGURE 2.For special applications or where extra deep sockets must be used the standard bar may be extended but only within the limitations shown on Figure 2. Alternative reaction bars are available, see page 5.WARNING: FAILURE TO OBSERVE THE LIMITATIONS SHOWN IN FIGURE 2 WHENMODIFYING STANDARD REACTION BARS MAY RESULT IN PREMATURE WEAR OR DAMAGE TO THE TOOL.Standard drive square extensions MUST NOT be used as these will cause serious damage to the tool output drive. A range of nose extensions is available for applications where access is restricted. These are designed to support the final drive correctly.The dimensions of the standard reaction bars are shown in the following table:Extra LengthSocketStandard Length Socket Torque Reaction should be taken in the shaded areas onlyWhen the PneuTorque ®is running the reaction bar rotates in the opposite direction to the output drive square and must be allowed to rest squarely against a solid object or surface adjacent to the fastener to be tightened.

Ensure the clockwise / counter-clockwise selector is correctly set.3. Rotate the handle into a convenient position relative to the reaction bar. Fit the tool onto the fastener tobe released with the reaction bar adjacent to the reaction point. See Figure 9.4. Adopt a suitable posture to counteract normal or unexpected movement of the tool due to reactionforces.5. Squeeze the trigger partially to bring the reaction bar into contact with the reaction point.6. Fully press trigger and keep fully pressed until threaded fastener releases.TIP: If unable to release the fastener due to the tool shutting off, increase the ‘StOP’ limit.If unable to release the fastener due to the tool stalling, increase the air pressure to the tool.Do not exceed the maximum air pressure for the tool.WARNING: EXCEEDING THE MAXIMUM AIR PRESSURE WILL CAUSE OVERLOADINGAND MAY LEAD TO SERIOUS DAMAGE.FIGURE 9 – Releasing Clockwise FastenerFIGURE 10 – Silencer Replacement MAINTENANCEFor optimum performance and safety, regular tool maintenance is required. The operator maintenance is limited to the replacement of the drive square and the silencer. All other maintenance and repair should be carried out by Norbar or a Norbar distributor. Maintenance intervals will depend on the tool usage and the environment in which it is being used. The maximum recommended maintenance and recalibration interval is 12 months.TIP: Steps the operator can take to reduce the amount of maintenance required include:1. Use the tool in a clean environment.2. Use an air compressor fitted with a dryer.3. Ensure the Lubro Control Unit has sufficient hydraulic oil.4. Ensure the Lubro Control Unit delivers hydraulic oil at the correct rate.5. Ensure the Lubro Control Unit is regularly maintained, see product handbook.6. Maintain the correct torque reaction.Air LubricationAdd Shell Tellus S2M 32 or equivalent good quality hydraulic oil to the Lubro Control Unit.GearboxUnder normal operating conditions it is not necessary to re-grease the gearbox. The gearbox contains Lubcon Turmogrease Li 802 EP or equivalent good quality grease.SilencerThe silencer (part number 18591) must be changed every 12 months. This may be more frequent for high tool usage or dirty environments.TIP: Change silencer with tool upside down, as shown, to ensure internal parts (spring & valve)are kept in place.1. Remove M4 screw (A) (part number 25381.10) using a2.5mm hexagon key.2. Remove pin (B) (part number 26284) using a pin punch.3. Pull out air inlet tube (D) with base plate & silencer.4. Remove silencer (E) from air inlet tube.5. Fit new silencer (part number 18591) over air inlet tube.6. Fit air inlet tube assembly (C, D & E) into handle against spring resistance.7. Fit pin (B) with a hammer.8. Fit screw (A) and torque to 0.5 N·m. Do not over tighten this screw as it is likely to break the base plate moulding.TIP: When refitting air inlet tube assembly into handlecare should be taken to ensure correct alignmentbetween air inlet tube & spring. It may be easier to fit the spring into air inlet tube first and secure with a small amount of grease.B AD EDrive SquareTo avoid internal damage (especially due to torque overload), the output drive square has been designed to shear first. This saves major internal damage and allows easy square removal. For drive square part numbers see page 5.FIGURE 11 – Drive Square ReplacementTo replace drive square:1. Remove the air supply.2. Support tool in a horizontal position3. Remove the screw or spring pin, then remove drive square.If the square has sheared it may be necessary to use pliers to remove the broken parts4. Fit new drive square.5. Fit new screw and tighten between 4 N·m to 5 N·m (for PTM52) or 8 N·m to 9 N·m (for PTM72/92/119)or insert new spring pin.6. Connect air supply.TIP: If the drive square fails continually then seek advice from Norbar or a Norbar distributor.CalibrationTo maintain the PneuTorque® accuracy it is recommended the tool is recalibrated at least every 12 months. Contact Norbar or a Norbar distributor for more information.CleaningKeep the tool in a clean condition to aid safety. Do not use abrasives or solvent based cleaners.DisposalRecycling Considerations:SPECIFICATIONSFIGURE 12 – Tool DimensionsRepeatability: Torque shut-off: ± 2% of reading.Angle shut off: ± 1 degree of rotationAccuracy: Torque shut off: +/- 2% of reading.Angle shut off: ± 1 degree of rotation: 6 degrees in 999 degrees maximum Display: 4 digit LED with refresh rate of 2.5 times per second.Units of Measurement: Newton metres (N·m) or pound force foot (lbf·ft.) - Operator selectable.
