Problems solved by technology

After the two-axis assembly is assembled by this method, the axial clearance of the gear has accumulated errors, and the exact value of the axial clearance of the gear cannot be actually obtained, and it is difficult to accurately control the performance of the output shaft
[0004] Measure the ring groove separately, and then match the thickness of the ring, resulting in accumulated errors in the rear clearance, making it difficult to accurately obtain the axial clearance of the gear, which needs to be resolved

Abstract

The invention discloses a direct measuring method and a direct measuring device for an axial moving clearance of a gear of an output shaft of a gearbox. The direct measuring method comprises the stepsof: S11, clamping and fixing the gear to be measured of the output shaft; S12, forcing the output shaft to displace along its axial direction; and S13 detecting displacement of the output shaft to obtain the axial moving clearance of the gear to be measured. The direct measuring device measures the clearance by means of fixing the gear and displacing the shaft, so that the self-measurement errorcan be minimized, and the occurrence of measurement deviation caused by the offset of a measurement point from the measured object is eliminated. The measurement type of the direct measuring method isdirect measurement, thus the measurement result has no accumulation error.

Description

technical field [0001] The invention relates to a method and a measuring device for directly measuring the axial movement gap of a gearbox output shaft gear. Background technique [0002] The output shaft is a key component of the gear transmission gearbox, and the assembly accuracy of the output shaft assembly directly affects the transmission performance of the gearbox. Since the gear and the output shaft can rotate relative to each other in the initial state of the synchronizer, there are gaps between the gear and the output shaft, and between the gear and the synchronizer. During the rotation of the output shaft, the gear on the shaft will move along the shaft. to move. [0003] For the two-axis assembly, at present, during assembly, the width of each gear assembly circlip groove is measured separately, and a circlip of corresponding thickness is equipped to control the clearance of the axial movement of the gear on the output shaft. After the two-axis assembly is asse...
