Abstract: The differential is an indispensable key component in the construction of automobiles, and the axial and angular tooth clearance between the internal gears is crucial for ensuring the reliability of vehicle operation. To achieve a low-cost, fast, and accurate measurement of the tooth clearance between different types of differential gears, this paper studies the actual usage of the existing measurement auxiliary tools and the analysis results of the measurement system for a method of measuring the tooth clearance between differential gears and its auxiliary tools. The study derives improvement strategies for the measurement method and designs a new measurement auxiliary tool. After testing and verification, the new measurement method and auxiliary tool have the advantages of convenient operation, reliable and stable measurement results, and strong product compatibility, providing favorable support for product quality control.
