AI Technical Summary

Technical Problem

Existing technology lacks effective tools to determine whether defects after gear grinding are within the grinding range, making it difficult to quickly determine whether gears are qualified.

Method used

A gear grinding inspection device was designed, including an inner ring and an outer ring. Inner and outer blocks are evenly distributed on the inner and outer rings. The blocks are matched with the shape of the gear to cover the two ends of the gear. Only the middle uncovered area is observed, and the gear is judged as qualified based on the color.

Benefits of technology

It enables a quick and easy way to determine whether defects after gear grinding are within the grinding range, ensuring the accuracy and efficiency of the test results.

Abstract

A gear grinding inspection device includes an inner ring and an outer ring. Inner blocks are evenly distributed on the outer side of the inner ring, with a gap A between every two inner blocks. Outer blocks are evenly distributed on the inner side of the outer ring, with a gap B between every two outer blocks. The inner and outer rings are fixed together by a connecting fitting, which does not occupy the space of gaps A and B. A gear grinding inspection method is also provided. During inspection, the inner and outer blocks of the gear grinding inspection device cover the two ends of the two sides of the gear teeth, and the uncovered parts of the two sides of the gear teeth are observed. The color of the uncovered parts allows for quick and easy detection of whether the ground gear teeth are qualified. The inspection is convenient and fast.
