齿面摩擦下非对称齿轮接触疲劳强度的计算
Calculation Based on Interteeth Friction on Contact Fatigue Strength of Asymmetric Gear
摘要
Abstract
The influence for the tooth face contact fatigue strength caused by the pressure angle for driving side profile and the sliding interteeth friction is analyzed on the driving gear of asymmetric spur gear drive system.The calculation equation for the contact fatigue strength of tooth face caused by the interteeth friction is deduced by analyzing the forces exerted on the asymmetric spur gear.The synthesis influenceing factor caused by the pressure angle for driving side profile and the sliding interteeth friction is proposed.The calculation results show that the effect of interteeth friction can't be neglected and increasing the pressure angle for driving side profile helps to enhance the tooth face contact fatigue strength.The results can reflect the changing regularity closing to reality for the tooth face contact stress.关键词
