Abstract

The invention relates to the technical field of speed changer testing, and discloses a speed changer testing device. The speed changer testing device comprises a locking assembly, a force applicationassembly and an angle gauge, wherein the locking assembly can lock an output end of a speed changer, the force application assembly is connected with the input end of the speed changer, and the anglegauge is used for measuring the rotation angle of the force application assembly. When the meshing situation of gears is tested when the speed changer is at a gear, the speed changer is put into the gear, an operator applies force to the force application assembly, the force application assembly drives the input end of the speed changer to rotate around the central axis of the speed changer untilthe force application assembly reaches a preset torque value, and the angle gauge measures the rotation angle of the input end of the speed changer, and calculates the meshing situation of the gears of the speed changer according to the rotation angle of the input end of the speed changer. By selecting different gears, the meshing situation of the gears of a transmission system in the speed changer at a certain gear can be measured, the speed changer does not need to be disassembled, the operation is simple, and the testing efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of transmission testing, in particular to a transmission testing device. Background technique [0002] The transmission is mainly used in vehicles and other mechanical equipment. Through the meshing of gears with different transmission ratios, the driving speed of the vehicle and the torque on the driving wheels can be changed in a wide range. [0003] In order to give full play to the best running performance of the transmission, improve the power of the car and the NVH (Noise Vibration Harshness, noise, vibration, harshness) performance of the vehicle, reduce the shock and frustration of shifting, and increase the ride comfort and ride comfort, It is necessary to test the gear mesh clearance and gear mesh stiffness of the internal transmission system of the transmission. [0004] In the prior art, the gear meshing clearance in the transmission is generally tested by using the lead pressing method, the rul...
