Compound full-tooth driven eccentric movable tooth driving device

Abstract

The invention relates to a compound full-tooth driven eccentric movable tooth driving device which comprises a shell, wherein a first circular wheel and a second circular wheel are further arranged in the shell, eccentric wheels which are used for driving the first circular wheel and the second circular wheel to swing and rotate towards different directions are arranged on eccentric rotating arms, a plurality of circular holes which are circumferentially and uniformly distributed are formed in the first circular wheel and the second circular wheel, the position of each circular hole in the first circular wheel is just coincident with that of each circular hole in the second circular wheel after rotating for 180 degrees along the axis of the first circular wheel, a limiting wheel is arranged between the first circular wheel and the second circular wheel, eccentric circular teeth are arranged in all of the circular holes in the first circular wheel and the second circular wheel, driving circular teeth and output circular teeth are respectively arranged on both sides of the eccentric circular teeth, and all of the driving circular teeth are positioned in the limiting wheel and are matched with the circular inner contour of the limiting wheel in an internally tangent mode. The acting force of the compound full-tooth driven eccentric movable tooth driving device on the limiting wheel, i.e. the shell, can be offset mutually, therefore, the stress is balanced, and the operation of the whole driving device is balanced.

Description

technical field [0001] The invention relates to a transmission device, in particular to a compound full-tooth drive eccentric movable tooth transmission device. Background technique [0002] The reducer is widely used, as long as the transmission device has a start-stop action or a speed change, the reducer is inseparable. Reducers can be roughly divided into ordinary reducers and high-performance reducers according to their performance. Ordinary reducers are mainly based on traditional involute gear transmission. Usually, the single-stage speed ratio is between 2 and 7. The performance is better, the precision and efficiency are very high, the design and manufacturing technology is very mature, and it can be manufactured industrially. Under the same speed ratio, it is large in size and heavy in weight, which cannot meet the needs of today's high-performance, compact and lightweight transmissions. High-performance reducers are mainly cycloidal planetary reducers with smal...

Problems solved by technology

[0004] Since the patent of the full-tooth drive eccentric movable tooth transmission device aims to provide a brand-new transmission device and mechanical transmission principle, it is focused on and easy to understand and popularize. Only the simplest form that can describe the transmission of the new structure mechanism is given. There is not much involved in multi-stage speed ratio adjustability, high rigidity and high load-bearing, dynamic stability, etc.
