Parallel-connected speed reducing and changing integrated end face oscillating tooth mechanism

Abstract

The invention discloses a speed reducing and changing integrated end face oscillating tooth mechanism. A base is connected with a left end cover. A through hole is formed in the middle of the left end cover. A bearing A is arranged at the through hole in the middle of the left end cover. An input shaft is connected with the bearing A in an inserted mode. The input shaft is connected with a driving disc. A trapezoidal groove is formed in the driving disc. The base is connected with a right end cover. A through hole is formed in the middle of the right end cover. A bearing B is arranged in the through hole in the middle of the right end cover. An output shaft is connected with the bearing B in an inserted mode. The output shaft is connected with a driven disc. A trapezoidal groove is formed in the driven disc. Circulating steel balls are arranged in the trapezoidal groove of the driven disc and the trapezoidal groove of the driving disc. The base is connected with an oscillating tooth carrier. The circulating steel balls move along a guiding groove. According to the speed reducing and changing integrated end face oscillating tooth mechanism, a reducing mechanism is not needed, and integral transmission of speed reducing and speed changing is achieved, so that the system efficiency is improved, the axial transmission space is reduced, the reduction ratio and the speed changing ratio can be adjusted independently, and flexibility is achieved. Manufacturing is convenient due to the fact that the steel balls are standard parts and driving disc tooth spaces and driven disc tooth spaces can be obtained through numerical control milling. The tooth forms of the driving disc and the driven disc are much simpler than those of non-circular gears, the number of engaged teeth is large, the strength is large, the bearing capacity is large and the transmission is stable.

Description

technical field [0001] The invention belongs to the field of variable speed ratio transmission, and in particular relates to a variable speed ratio end face movable tooth transmission mechanism. Background technique [0002] With the diversification of production, the machinery is developing in the direction of complexity, and the uniform speed transmission can no longer meet the complex transmission requirements. In order to realize complex production, non-uniform speed transmission plays an increasingly important role in production. [0003] The cam mechanism is one of many speed change mechanisms. Although it can achieve variable speed ratio transmission, the cam mechanism is easy to wear and has noise. The application is very limited; the non-circular gear combines the characteristics of the cam and the gear, and can realize the precise speed ratio between the two shafts, so as to realize the non-uniform continuous transmission. However, due to the high manufacturing c...

Problems solved by technology

Chen Zhitong and others proposed a design method for the non-uniform movable gear mechanism that simplifies the variable speed ratio transmission into the superposition of linear motion and sinusoidal motion, but the simplified transmission function cannot fully meet the complex and variable non-uniform motion requirements in actual production.

Based on the theory of non-circular gears, Liu Dawei and others proposed a non-uniform push rod movable tooth mechanism, which can realize the transmission effect of multi-period non-circular gears. However, there are many parts in this mechanism and the push rod is not stressed for about half of the cycle.

In addition, there is a single-row movable tooth mechanism. Although it can realize the integrated transmission of deceleration and speed change functions through a simple structure, it must be used in series with the deceleration mechanism, which not only increases the complexity of the mechanism, reduces the efficiency of the system, and cannot Give full play to the characteristics of large reduction ratio of conventional movable tooth mechanism

Its reduction ratio is controlled by the cycle number of the transmission ratio, which can only be adapted to some special occasions, but cannot realize the combination of any reduction ratio and transmission ratio
