Abstract

The invention discloses a circumferential tooth gap measuring and coloring positioning device for a bevel gear pair. The device comprises a tension shaft, a pressing shaft, a fixing frame, a bearing,an expansion group, and a locking group. The fixing frame is fixedly installed on a shell of an output end speed reducer. The bearing is installed on the fixing frame. The pressing shaft is sleeved with the bearing and extends into an output gear. The tension shaft penetrates through the pressing shaft, is in threaded connection with the pressing shaft, and exceeds the pressing shaft by an end part of the output gear. The expansion group is installed at an over end of the tension shaft and is in expansion with the inner wall of the output gear. The locking group is installed on the fixing frame and the pressing shaft, and locks and positions the axial and radial directions of the pressing shaft. The device has the advantages of being simple and convenient to operate, free of pollution, andcapable of realizing rotation stop positioning and coloring inspection.

Description

technical field [0001] The invention mainly relates to the technology for measuring the circumferential backlash after the bevel gear pair of the reducer is assembled, in particular to a measuring and coloring positioning device for the circumferential backlash of the bevel gear pair. Background technique [0002] According to the requirements of "Instructions for Tail Reduction Assembly in Transmission System", it is necessary to measure the actual circumferential backlash of the bevel gear pair in the transmission system after assembly. [0003] The method used in the field is to stick lead wire on the tooth surface of the bevel gear, and after rotating the gear to flatten the lead wire, measure the thickness of the flattened lead wire to obtain the backlash value. The defects and deficiencies of this method are mainly reflected in: 1. During assembly, the operation can only be performed from the observation window of the oil surface of the shell, and the space is small, s...
