DYNAMICAL BALANCE STUDY OF RING REDUCER WITH SMALL TOOTH NUMBER DIFFERENCE AND PARALLEL AXIS

摘要

The single-ring, double-ring, three-ring and four-ring reducers are a 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 characteristics such as simplicity and compactness in structure, large transmission ratio, high efficiency and so on. As the three-ring reducer was invented only ten years ago, 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. Study on the force performance of single-ring, double-ring, three-ring and four-ring reducer is carried in this dissertation and the force analysis model of ring reducer is built. Following this, it is concluded that the present ring reducers have the problem that the inertia force or the inertia moment is lopsided. On the base of analysis and calculating the balance ring reducer and its concretely carrying out step are brought forward. Compared with ring reducer of the same power, the balance ring reducer has many advantages, such as: low vibration noise, low cost and less production difficulty. Therefore, it has important theoretic significance and highly practical engineering value.
