摆线轮的切齿加工,通常均由专用的摆线切齿机(如在秦川机床厂生产的Y7654型机床上切齿)加工。对于单件、小批生产的工厂,可结合本单位的设备情况,采用自行设计简易的加工摆线齿轮装置。摆线针轮行星传动原理及其啮合关系与“一齿差”行星齿轮传动是相似的。因此,当设计摆线轮齿形加工装置时,运用“一齿差”行星齿轮传动原理是完全可行的。只要保证形成摆线齿形的滚圆直径、基圆直径、发生圆直径、偏心距及传动此关系不变,就可加工出精确的摆线轮齿形。必须指出,由于少齿差行星齿轮的传动通常受到齿形干涉的限制,往往采用大角度正变位制的方法,其啮合节圆直径及偏心距将发生变异,不能满足摆线针轮行星传动所要求的滚圆,基圆直径比及偏心距的要求,故需要加以修正。为此,在摆线轮切齿加工装置设计中,应确保摆线针轮传动的各个参数不变,这是该装置设计应考虑的基本问题。
Cycloid gear cutting, usually by a dedicated cycloid gear cutting machine (such as the Y7654 produced in Qinchuan Machine Tool Factory cutting machine) processing. For a single, small batch production plant, can be combined with the unit’s equipment, the use of simple design cycloid gear device. Cycloid planetary gear transmission principle and meshing relationship with the “one tooth difference” planetary gear transmission is similar. Therefore, when designing the cycloid gear processing device, the principle of “one tooth difference” planetary gear drive is completely feasible. As long as the shape of the cycloid to ensure the formation of the spheronization diameter, diameter of the base circle, the occurrence of circular diameter, eccentricity and transmission of this relationship unchanged, you can work out accurate cycloid tooth profile. It must be pointed out that, due to the transmission of the small tooth difference planetary gear is usually limited by the tooth-shaped interference, the method of large angle positive displacement is often adopted. The meshing pitch diameter and eccentricity will vary and can not meet the requirements of the cycloid planetary transmission The required rounding, base diameter ratio and eccentricity requirements, it needs to be amended. Therefore, in the cycloid gear cutting device design, should ensure that the various parameters of the cycloidal pin drive unchanged, which is the device design should consider the basic issues.
