Abstract

The present invention discloses a gear box on-line comprehensive performance test method, pertaining to the field of engineering machinery. According to the method, all performance indexes, such as the gear-shifting pressure, the lubrication pressure, the gear-shifting oil-way tightness, the torque converter oil pressure, the output torque and the output rotational speed, of the gear box are tested via an on-line comprehensive performance test table. The on-line comprehensive performance test table comprises a test table body, a hydraulic system and a computer control system. The test table body is fixedly provided with a drive motor, a coupling A, a coupling B and a braking system. The drive motor is connected with the input end of the coupling A, the input end of the coupling B is connected with a transmission shaft, and the output end of the coupling B is connected with the braking system. The coupling A and the coupling B are separately provided with an input torque and rotationalspeed sensor and an output torque and rotational speed sensor. The method can perform comprehensive test on the performance indexes of the gear box and ensure the 100% one-time delivery qualified rateof the performance of the gear box, and the in-plant commissioning and repairing cost and the market failure maintenance cost of the gear box are reduced.

Description

technical field [0001] The invention belongs to a performance testing method, in particular to an online comprehensive performance testing method of a gearbox. Background technique [0002] As the core transmission part of the loader, the gearbox can realize the power conversion and transmission from the engine to the drive axle. Its main functions include: changing the transmission ratio to meet the power and speed requirements of the loader when driving; down, make the loader realize reverse running; use the neutral gear to cut off the power transmission, so that the engine can start and idle. The handling, transmission and safety of the gearbox directly affect the performance of the loader, so the test of the gearbox is very important. [0003] Transmission on-line testing is an important process of transmission production. By testing the key performance of the transmission, the quality of the transmission can be guaranteed to meet the requirements of the whole machine. ...
