A Study on Dynamical Balance of a Ring Reducer with Small Tooth Number Difference and Parallel Axis

A reducer with single, double, three or four-ring is a new kind of gear drive developed in thepast decade. Adopting the new conception of “parallel and movable axis” of multiple mechanisms, this kind of gear drive has many characteristics such as simplicity and compactness in structure, large transmission ratio, high efficiency and so on. As a three-ring reducer has been invented only for ten years, up to now its design is available only with the analogue method and no design theory can be followed. There exist serious vibration and noise in transmission, which limit its wide application in industry.　　Study on force performance of single-ring, double-ring, three-ring and four-ring reducers was carried out in this dissertation and the force analysis model of a ring reducer was built. Following above all, it was concluded that the present ring reducers have the problem that the inertia force or the inertia trisquare was lopsided. On the basis of analysis and calculating the balance ring reducer and its concretely carrying out step were brought forward. Compared with ring reducer which had same power, the balance ring reducer had many functions, such as low vibration noise, low cost and less production difficulty. Therefore, it has important theoretic sense and high engineering practical value.
