Machinery's Handbook 28th Edition INVOLUTE SPLINES Page 1 of 38 Copyright 2008, Industrial Press Inc., New York, NY - INES AND SERRATIONS (翻译:朱晓峰,浙江,金华) A splined shaft isone having a series of parallel keys formed integrally with the shaft and mating with corresponding grooves cut inahub or fitting; this arrangement is in contrast toa shaft having a series of keys or feathers fitted into slots cut into the shaft. The latter construction weakens the shaft toa 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 tobe 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。译注 A1 :“ slidably-mounted ”例如球笼式等速万向节, 万向节同时能转动一定角度;“ ermanently-fixed gears ”例如齿轮变速箱。( 凡是带“译注”的,表示译者的理解,下同) Splines having straight-sided teeth have been used in many applications (see SAE Parallel Side Splines for Soft Broached Holes in Fittings); however, the use of splines with teeth of involute profile has steadily increased since 1) involute spline couplings have greater torque-transmitting capacity than any other type; 2) they can be produced by the same techniques and equipment as is used to cut gears; and 3) they have a self-centering action under load even when there is backlash between mating members. 具有“直边式齿形”的花键已经适用于多种场合(请查看“用于软拉削加工成型的直边式花键”);然而,“齿侧具有渐开线形状的花键”的使用正在逐步的增长,原因如下:1)渐开线花键传递扭矩的性能超过其他形式;2)可用加工齿轮的技术或设备来加工; 3)在内齿和外齿配合情况下产生的反作用力具有自定心功能。译注 A2 :“ Parallel Side Splines ”指的是矩形花键,文中翻译成“直边式花键”,见《 GB/T 1144 矩形花键尺寸
