摆线针轮行星传动中的行星轮齿廓曲线为等距短幅外摆线。这种传动具有体积小、重量轻、传动比范围大、效率高、结构合理、寿命长等优点。但也存在下面的主要缺点: (1) 转臂轴承的受力较大,尤其当工作连续性大的情况下,承载能力往往受转臂轴承寿命的限制。 (2) 零件的制造精度要求较高,加工工艺比较复杂。针对上述缺点,对行星轮的摆线齿廓作适当修正,可改善转臂轴承受力情况,并降低对摆线轮和针轮的制造精度要求。但应指出,摆
Cycloidal pinion planetary gear planetary gear profile curve is equidistant short epicyclic. This drive has a small size, light weight, a large transmission ratio, high efficiency, reasonable structure, long life and other advantages. However, there are also the following main disadvantages: (1) The bearing force of the boom bearing is large, especially when the work continuity is large, and the bearing capacity is often limited by the bearing life of the boom bearing. (2) high precision parts manufacturing, processing more complex. In view of the above shortcomings, the cycloid tooth profile of the planetary gear can be properly modified to improve the bearing force of the boom arm and reduce the manufacturing precision requirements of the cycloidal gear and the pin wheel. However, it should be pointed out
