Internal spline expansion sleeve structure for measuring jumping of speed reducers

Abstract

The invention discloses an inner spline expansion sleeve structure for measuring the runout of a reducer, which includes an inner ring, an outer ring and a shaft; the inner ring includes an inner ring flange and an inner ring cone head fixedly connected to one side thereof , the inner ring flange is provided with an inner ring mounting hole; the outer ring includes an outer ring flange and an outer ring taper hole fixedly connected to one side thereof, and the outer ring flange is provided with an outer ring mounting hole and Disassemble the threaded hole; the taper hole of the outer ring is placed in the inner spline of the reducer, the taper head and shaft of the inner ring are placed in the taper hole of the outer ring in turn, and the mounting hole of the inner ring and the mounting hole of the outer ring are fastened by bolts. The invention uses the expansion sleeve to realize the connection between the spline in the reducer and the shaft, converts the rotation of the spline in the reducer to the rotation of the shaft, and converts the measurement of the processing accuracy of the internal spline into the runout of the end face and the stop of the reducer The measurement brings convenience to the measurement. The expansion sleeve has a simple structure, low cost, convenient disassembly and installation, and improves the measurement efficiency.

Description

technical field [0001] The invention relates to the runout measurement of the reducer, in particular to an internal spline expansion sleeve structure for measuring the runout of the reducer. Background technique [0002] In recent years, new energy vehicles have developed rapidly, and drive motors, as power devices for new energy vehicles, have also received widespread attention. The existing drive motor has a problem that is difficult to eliminate - the abnormal noise of the motor. There are many influencing factors for the abnormal noise, and the coordination accuracy of the motor and the reducer has a greater impact on it. The driving motor and the reducer are generally connected by splines, so the processing accuracy of the splines in the reducer directly determines the reliability of the motor operation. At present, there are few devices used to measure the machining accuracy of the splines in the reducer, and the structures are complicated, the operation is inconvenie...
