A Study on Fp Z/8 of Anti-Backlash Gear in an Engine

Abstract

The high speed of an engine balance box may cause significant additional gear noise. Gear accuracy is themost useful key to reduce gear noise, but the small tooth width and thin-walled anti-backlash gear introducechallenges to the manufacturing process. In order to reduce the gear noise caused by gear pitch error, thispaper investigates the correlation between influencing factors and gear pitch error by analyzing the processingtechnology, tooling fixture, and equipment accuracy. By improving the process and optimizing the geardesign, the gear machining accuracy was improved and the processing cost was saved.
