分析平行轴摆线针轮减速器或增速新型传动装置的结构、原理和齿廓方程 ,进行齿顶曲线优化 ,根据变形协调条件建立平衡方程 ,对提出的力学模型进行了受力分析。研究结果表明 ,环板和连杆的受力呈简谐规律变化 ,沿水平方向存在较大的冲击力 ,两块环板可实现力平衡 ,但需要克服死点的辅助机构实现动力连续传动。 The structure, principle and tooth profile equation of the parallel axis cycloid reducer or new gearbox are analyzed to optimize the tooth top curve. The equilibrium equation is established according to the deformation coordination condition, and the mechanical analysis of the proposed mechanical model is carried out. The results show that the force of the ring plate and the connecting rod changes in a simple harmonic law and there is a big impact force in the horizontal direction. The two ring plates can achieve the force balance, but the auxiliary mechanism to overcome the dead point needs to realize the power continuous transmission.
