Gear ring defect detection device and method

Abstract

The invention provides a gear ring defect detection device and method, and relates to the technical field of gear ring defect detection. The device comprises a control module, a detection module and a display module; the control module is in communication connection with the detection module and the display module. The detection module is in communication connection with the display module; the control module is used for generating a control instruction and sending the control instruction to the detection module; the detection module is used for detecting defects of the gear ring according to the control instruction to obtain detection data and sending the detection data to the display module; and the display module is used for generating display data according to the detection data, displaying the display data and sending the display data to the control module. The internal defects of the gear ring can be detected, and the problem that the internal defects of the gear ring are difficult to detect due to the structural shape is solved; and whether the gear ring has crack propagation or not can be monitored in the operation process, the crack can be found when the crack is in a small state, and the safe operation reliability of equipment is improved.

Problems solved by technology

[0003] As a key component of the shield machine, the ring gear of the main bearing of the shield machine is very important for the safe operation of the shield machine. According to statistics, cracks and root fractures of the tooth root of the ring gear are its main failure modes. Once it occurs during the operation of the shield machine Root fracture will cause jamming, vibration, and damage to planetary gears and reducers, which will eventually lead to adverse consequences such as delays in construction period and difficulty in replacement

At present, the main bearing ring gear of the shield machine does not have online inspection equipment and instruments, and the offline non-destructive testing is mainly limited to surface testing methods such as magnetic particle testing and penetrant testing. It is not special for the internal testing of gear teeth, especially the internal testing of tooth roots. Attention, and because of the root rounding, conventional ultrasonic flaw detection is difficult to perform comprehensive flaw detection due to the gear tooth structure
