Bevel gear transmission error test method based on strain method

Abstract

Abstract The testing and measurement of dynamic transmission error in cone gears is highly challenging in oil-based environments, where conventional testing methods are often limited in scope. To address this issue, a testing method utilizing strain sensors was proposed to measure dynamic transmission error in cone gears. To verify the feasibility of this testing method, a testing platform was designed and constructed specifically for cone gear transmission error testing. During the testing process, temperature-induced interference was compensated using a quarter-bridge configuration to enhance the reliability of test data. Additionally, a magnetic grid method was used to synchronously measure dynamic transmission error in cone gears. Comparative analysis of test results from the two different testing methods was conducted under various operational conditions of the cone gears. The comparison successfully verified the feasibility of the stress-strain-stiffness method in measuring dynamic transmission error in cone gears. This study provides a new, quick, simple, and practical testing method for measuring dynamic transmission error in cone gears, which can be valuable for academic research and practical applications.
