简易卧式铣床传动装置设计摘要本设计为简易卧式铣床的传动装置设计。
由于此设计需要按照工厂的具体情形（条件），自行设计，制造，能供本厂生产利用的简单的机床，所以本设计是依照工厂生产需要，进行有针对性的设计制造。
在设计进程中发觉，能够利用方案有很多种，可是大部份传动方案由于传动比和结构方面的原因不能利用，只有采用蜗杆—圆锥齿轮减速器。
传动比的分派本着机体结构简单、体积小、重量轻的原则来肯定，传动零件的设计应尽可能选用既能知足要求有是价钱低廉的材料。
按照卧式铣床的特点主要利用了两级传动装置，第一级利用了蜗杆减速器，第二级采用了圆锥齿轮减速器，而且这两级减速器别离独立，各为一体。
主如果考虑其以后的改装方便和经济性易保护等方面，例如：蜗杆减速器为多用途设计，在本设计中为下置式，若需要上置式则能专门快捷方便的进行改装。
本设计的重点和难点部份为多功能蜗杆减速器的设计，它能改成蜗杆上置式工作，也能改成蜗杆下置式进行工作。
可利用有限的物力和财力对机床做多功能的改造。

As a result of this design needs according to the factory special details (condition), independently to design, the manufacture, can supply this factory production use the simple engine bed, therefore this design defers to the plant production need, carries on has the pointed design manufacture.Discovered in the design process that, may have very many kinds using the plan, but majority of transmissions plan because the velocity ratio and the structure aspect reason cannot use, only then uses the worm bearing adjuster bevel gear reduction gear. The velocity ratio assignment in line with the body structure simple, the volume is small, the weight light principle determined that, the transmission components design should select as far as possible already can answer the purpose has is the price inexpensive material. Has mainly used two levels of transmission devices according to the horizontal milling machine characteristic, the first level has used the worm reducer, the second level has used the bevel gear reduction gear, and these two levels of reduction gears distinction is independent, each is a body. Mainly is considered its later the reequipment convenience and the efficiency will be easy to maintain and so on the aspect, for example:The worm reducer is the multipurpose design, in this design for down-alex, if needs onto set at the type then can very quick Czechoslovakia facilitate carries on the reequipment.This design key point and the difficulty partially for the multi-purpose worm reducer design, it can alter to on the worm bearing adjuster to set at the type work, also can alter to the worm bearing adjuster down-alex to carry on the work. May use the limited physical resource and the financial resource makes the multi-purpose transformation to the engine bed.Keyword: Simple engine-bed decelerating device transmission目录简易卧式铣床传动装置设计 (1)1 .简易卧式铣床的传动装置的设计 (8)前言 (8)2．传动装置设计 (9)铣床的熟悉 (9)铣床的传动方式 (10)3.选择电动机 (11)原始参数 (11)电动机的选择 (11)4.传动方案的选择： (12)计算总传动比 (12)选择传动形式 (12)传动方案的选择 (13)方案一： (13)方案二： (14)方案三： (15)方案四： (16)方案综合考虑并选用 (17)5.按照传动方案计算运动参数 (18)传动比的分派 (18)蜗杆,蜗轮传动计算(<机械设计手册>机械工业出版社) (18)选择材料 (18)选择蜗杆蜗轮的齿数 (19)肯定许用应力 (19)按接触强度计算； (19)求蜗轮的圆周速度，并校核效率，实际传动比： (20)校核蜗轮齿面的接触强度 (21)蜗轮齿根强度校核 (21)计算几何尺寸 (22)各轴段轴向长度的肯定 (24)按许用弯曲应力校核轴 (24)蜗杆，蜗轮简图 (26)蜗杆减速器轴承的选用 (27)蜗杆轴轴承的选用 (27)蜗轮轴轴承的选用 (28)锥齿轮传动设计：（进程见《机械零件设计手册》第三版） (30)初步设计： (30)几何计算。
