    摘要:

    精密钢球行星减速机构是一种高效节能的摆线类传动形式,设计一种二级摆线钢球减速机构,其利用减速钢球作为传动介质,在外摆线槽和内摆线槽构成的循环滚道中进行无间隙啮合传动,分析摆线减速机构的传动原理,对不同类型的减速机构的传动比进行计算。利用动力学仿真软件ADAMS平台,做二级摆线减速机构的运动学模拟仿真,得到运动过程中行星盘和摆线盘的角速度和角加速度曲线,验证分析减速机构的运动平稳性和传动合理性,为二级摆线减速机构的结构优化设计和减速比设计提供理论依据。

    Abstract:

    The precision ball planetary reducing mechanism is a type of highefficiency and energysaving cycloidal transmission mechanism. Here, a twostage cycloidal ball planetary transmission mechanism (CBPTM) is designed, which employed the deceleration balls as the transmission mediumand achieved the gapless meshing transmission in a circulating raceway formed by the epicycloid groove and the hypocycloid groove. The transmission principle of the planetary reducing mechanism is analyzed, and the transmission ratios of different types of the CBPTM are calculated. Based on the platform of automatic dynamic simulation software ADAMS, the kinematics simulation of the twostage CBPTM is conducted, meanwhile, the angular velocity, angular acceleration curves of the planetary disc and the cycloidal disc during the movement process have been obtained. The smoothness of motion and transmission rationality of the deceleration mechanism have been verified and analyzed, which provides the basis for the structural optimization and transmission ratio design for the twostage cycloidal ball planetary reducing transmission.
