内齿圈齿形误差对行星齿轮振动特性影响研究
The impact of internal ring gear tooth profile error on the vibration characteristics of planetary gear systems
摘要
Abstract
To explore the impact of internal gear tooth profile errors on the vibration characteristics of planetary gears,this paper takes an automotive planetary gear transmission as the research object.A multi-body dynamics model of the gearbox is built.Based on actual measured tooth profile data,a flexible body model of the internal gear ring with tooth profile errors is built using the node movement method.A rigid-flexible coupled model of the planetary gearbox is developed.Then,a vibration intensity test platform for the planetary gearbox is built,and the accuracy of the model is verified by comparing the vibration intensity data under three different working conditions.Next,the vibration characteristics affected by internal gear tooth profile errors in planetary gearboxes with different accuracy levels are systematically studied under various working conditions.Results indicate the tooth profile errors of high-precision internal gears have a minimal impact on vibration characteristics,while those of low-precision gears have a significant impact.Furthermore,using the full-factorial experimental design method,the correlation between internal gear tooth profile errors and the vibration characteristics of planetary gears is further explored.It is also shown that both tooth profile deviation and helix deviation are positively correlated,with the impact of tooth profile deviation markedly higher than that of helix deviation.关键词
