摘要
摆线针轮行星减速器不仅广泛应用于通用传动领域,而且在机电一体化系统中具有极为广泛的应用潜力。摆线针轮行星减速器的制造精度要求高,轮齿啮合时容易产生干涉、点蚀、胶合以及折断现象,影响减速器的振动、寿命和可靠性。一种带橡胶圈的新型摆线针轮行星减速器被提出,通过有限元方法对比传统、新型减速器的接触变形,新型减速器的关键零件具有更大的变形量。因此,新型减速器能够通过弹性变形实现缓冲和容差作用,进而增强多齿啮合效应,提高承载能力和可靠性。
Cycloid speed reducers have been widely used in various fields of common transmission. Besides, cycloid drives have also had great potentials for the application in the fields of mechatronics system. The precision of manufacturing cycloid speed reducers is highly required and therefore when the gear teeth are engaged, phenomena such as interference, pitting, agglutination and fracture are subject to change more likely to appear, which affects the vibrations of the reducer, as well as its life span and reliability. This paper proposes a new type of cycloid speed reducers and compares the contact deformation of both the traditional and new-type speed reducers by adopting the finite element method. The critical parts of the new-type reducer have higher deflections. Therefore, the new cycloid speed reducers are able to function better in the buffer and tolerance by elastic deformation, strengthen the multi-teeth meshing effects and improve its bearing capacity and reliability.
