Problems solved by technology

However, in fact, due to the existence of objective phenomena such as shaft hole machining tolerances, installation tolerances, temperature changes, and gear wear, the rotating shafts cannot be absolutely parallel, which is to cause vibration, noise, increased wear, shortened life, and reduced machining accuracy of the transmission. one of the reasons

Embodiment 1

[0056] The sun—the rocker in the planetary gear train is replaced with two eccentric rings, namely the outer ring runner A and the inner ring runner B. Such as figure 1 , 2 shown.

[0057] The outer ring runner A is composed of an outer circle and an inner circle, and its outer circle center is the center of the sun wheel axis O A , its inner center is the axis O of the planetary wheel B , O A with O B The distance between is the outer ring eccentricity R A .

[0058] Inner ring runner B is also an eccentric ring. The center of its outer circle coincides with the center of the inner circle of the outer ring runner A, which is O B . Its inner circle center M is the center of the target axis, O B The distance from M is the inner ring eccentricity R B .

[0059] Order R A =R B , then the trajectory of the target axis axis M can be covered by O A as the center of the circle, with R A +R B is the circular area with radius, that is, M can reach any point within this...

Abstract

The invention relates to a double eccentric circle mechanism with a transmission shaft circle center adjustable in position. A moving rule of a sun wheel and planet wheel mechanism in mechanical transmission is adopted. The mechanism is characterized in that the adjusting method of the double eccentric circle mechanism includes an arc moving method and a linear moving method, the arc moving method means that moving is carried out in arc tracks, and the linear moving method means that a target rotary shaft moves along linear tracks; the position of the center of the rotary shaft can be adjusted after the rotary shaft is installed, the position of a shaft hole base is fixed, and the position of the center of a bearing is adjusted; by means of rotation of two eccentric annular rings sleeved together, a middle hole axis position of the inner eccentric annular ring moves, and the aim of adjusting the middle hole axis position is achieved; precision of a part machined through a lathe depends not only on machining precision of all parts comprising the lathe but also on installation precision of transmission pairs in a transmission system; meshed gears are used for transmitting power and is, more importantly, used for guaranteeing different rotation speeds for machining of the parts and precise moving distances of a cutter.

Description

technical field [0001] The invention relates to a double eccentric circle mechanism with adjustable center position of a transmission shaft, which is mainly used in the design and manufacture of machine tools and other transmission devices, and also relates to the mechanical field of adjusting the installation position of the shaft center (circle center). Background technique [0002] In a mechanical transmission structure such as a gearbox, the gears meshing with each other are installed on the rotating shaft. In order to make the gears in the best meshing working state, it is hoped that the rotating shafts are installed parallel to each other. However, in fact, due to the existence of objective phenomena such as shaft hole processing tolerances, installation tolerances, temperature changes, and gear wear, the rotating shafts cannot be absolutely parallel. one of the reasons. [0003] After scientific assembly of parts with general precision, a transmission system with hig...
