Online detection system for main speed reducer assembly test

Abstract

The invention discloses an on-line detection system for a main speed reducer assembly test. The on-line detection system comprises a measurement and control cabinet, a plurality of PLC switching cabinets and a detection device; the measurement and control cabinet comprises an industrial personal computer and a display; the PLC transfer cabinet comprises a PLC module and a signal conditioning module; the detection device comprises a noise sensor, an infrared temperature measurement sensor and a pressure sensor which are respectively installed at corresponding positions on a test bed for testinga main speed reducer assembly and connected with the input end of a signal conditioning module, the output end of the signal conditioning module is connected with a PLC module, and the PLC module anda display are both connected with an industrial personal computer. The system realizes the functions of online acquisition, storage, printing and the like of test data, the test data is real, and theinfluence of human factors is avoided; abnormal phenomena in the test process can be timely alarmed, so that the expansion of accidents is avoided; meanwhile, an operator does not need to monitor ina test room, man-machine isolation is achieved, potential safety hazards are eradicated, and the intrinsic safety of the process is improved.

Description

technical field [0001] The invention relates to the field of main reducer assembly test and detection, and specifically relates to an online detection system for main reducer assembly test. Background technique [0002] As an important part of the chassis transmission system, the axle is required to undergo no-load bench tests before leaving the factory: including noise tests, temperature rise tests, and sealing performance tests. During the test, the noise test, temperature rise test, sealing performance test, etc. need to be tested, and the test is arranged for special personnel to operate, and the following problems exist: [0003] 1) The test operation process is controlled by the operator, and the test time and speed are greatly affected by human factors; [0004] 2) After the test is completed, various data are collected and filled in by the operator, and the test results are greatly affected by human factors; [0005] 3) Abnormal phenomena such as bearing ablation a...

AI Technical Summary

Problems solved by technology

[0003] 1) The test operation process is controlled by the operator, and the test time and speed are greatly affected by human factors;

[0004] 2) After the test is completed, various data are collected and filled in by the operator, and the test results are greatly affected by human factors;

[0005] 3) Abnormal phenomena such as bearing ablation and high oil temperature during the test cannot be detected in time, which may easily cause accidents;

[0006] 4) During the test, operators and inspectors need to monitor in the test room, there are harmful factors such as object impact, scalding, noise and the risk of high temperature heatstroke
