Gear defect detection system

The invention discloses a gear defect detection system, and relates to the technical field of gear defect detection.The gear defect detection system comprises a low-speed heavy-load test module, a high-speed heavy-load test module, an early warning terminal and a database. Gear oil film information, corresponding to the low-speed heavy-load test groups, of the test gear is collected, gear oil film states corresponding to the low-speed heavy-load test groups are analyzed and judged, meanwhile, the high-speed load test groups are arranged, the test gear is tested, gear information corresponding to the high-speed load test groups is collected, and gear oil film states corresponding to the high-speed load test groups are analyzed and judged. The gear operation state corresponding to each high-speed test group is obtained through analysis and judgment, so that comprehensive and effective defect judgment data support is obtained, gear defect detection is carried out from multiple aspects, the accuracy of gear defec
