摘　　要：在对N型内齿行星齿轮传动的基本结构形式———单环、双环、三环及四环减速器的基本结构和传动机理分析的基础上 ,对环式减速器的发热问题进行了研究 ,探讨了引起环式减速器发热的主要原因和部位 ,发现箱体支承轴承和环板高速轴承发热严重是主要发热源。提出了解决发热问题的具体措施 ,该措施经实验验证很好地解决了环式减速器的发热问题 ,提高行星轴承及减速器的使用寿命 ,具有重要的工程实用价值。The single-ring, double-ring, three-ring and four-ring reducers are new kind of gear drive developed in the past decade. Adopting the new conception of “parallel and movable axis” of multiple mechanisms, this kind of gear drive has many characteristic such as simplicity and compactness in structure, large transmission ratio, high efficiency and so on. As the three-ring reducer has been invented only for ten years, up to now the design of the gear drive is only made with analogue method, no design theory can be followed, there exist serious vibration and noise in transmission, which limit its wide application in industry. On the base of the principle of transmission and basic configuration of single-ring, double-ring, three-ring and four-ring reducer,the problem about heating of ring reducer and the primary reason and the part which result in heaating are discussed. Moreover, the result is tested through the corresponding experiment and the concrete measure about resolving the heating problem is put forward. It is proved that the measure can commendably resolve heating of ring reducer and extend the using life of epicyclic bearing and the ring reducer. So it has important theoretic sense and engineering practical value.
