摆线类机械的工作原理如图1所示,针轮固定不动,而摆线齿轮在针轮内作行星运动,即摆线齿轮的中心O绕针轮中心O′公转,在此同时,摆线齿轮还绕自己的中心O在反方向自转。对于一齿差啮合,在摆线齿轮中心O绕固定的针轮中心O′公转一周时,摆线齿轮相对于针轮反方向转动一个齿。若摆线齿形未作修正及不存在制造误差,理论上具有针轮上的每个针齿与摆线齿轮上每个齿都进行啮合的特点。假使针轮和摆线齿轮存在周节相邻和累积以及齿形等加工误差,无论存在的误差程度如何,对 Cycloid class machinery works as shown in Figure 1, the pin wheel fixed, and the cycloid gear planetary motion in the pin wheel, that cycloid gear center O around the pin wheel center O ’revolution, at the same time, Cycloidal gear around its own center O in the opposite direction of rotation. For a tooth difference meshing, when the cycloidal gear center O revolves around a fixed pin wheel center O ’for one revolution, the cycloidal gear rotates one tooth counter to the pin wheel. If the cycloid tooth shape is not corrected and there is no manufacturing error, theoretically, each pin gear on the pin wheel is meshed with each tooth on the cycloidal gear. If the pinwheel and cycloid gear adjacent to the week and there is accumulation and tooth processing errors, no matter what the extent of the error, the
