AI Technical Summary

Technical Problem

After prolonged use, the wear of gears in existing planetary gear reducers leads to a significant discrepancy between the backlash test results and those obtained during factory quality inspection. Conventional testing equipment introduces errors and cannot effectively control non-structural micro-clear gaps.

Method used

A dynamic oil film compensation system for lubricant is adopted, which continuously supplies lubricant to the planetary reducer through multiple delivery pipes and electronic valves. Combined with temperature sensor monitoring and support frame structure, it ensures stable gear meshing and prevents wear and temperature rise from affecting detection accuracy.

Benefits of technology

This improves the detection accuracy of the torque sensor, reduces unstructured micro gaps, ensures the accuracy and consistency of the detection results, and prevents the detection results from being affected by displacement or shaking.
