齿轮传动的运动精度即齿轮啮合的传动比在一转内的一致性,运动的不精确性以运动误差来表示.本文分析了齿形范成时由于传动比变动造成的基圆距变动,提出了齿轮上左、右齿形基圆分离的概念.分析了对基圆双偏心可能实现的补偿。齿轮传动的主要用途是按给定角速比由主动轴向从动轴传递回转运动,其基本啮合定理为:
The motion accuracy of gear transmission is the consistency of the gear ratio of gear meshing in one revolution and the inaccuracy of motion is expressed by motion error.This paper analyzes the variation of base pitch caused by the gear ratio variation when the gear shape is formed, On the left and right tooth base circle separation concept.The analysis of the base circle double eccentric possible compensation. The main purpose of the gear drive is to transmit rotary motion from the active axial driven shaft according to the given angular speed ratio. The basic meshing theorem is:
