Internal spline expansion sleeve structure for measuring jumping of speed reducers

Abstract

The invention discloses an internal spline expansion sleeve structure for measuring jumping of speed reducers. The internal spline expansion sleeve structure comprises an internal ring, an external ring and a shaft. The internal ring comprises an internal ring flange and an internal ring conical head, a side of the internal ring flange is fixedly connected with a side of the internal ring conicalhead, and internal ring mounting holes are formed in the internal ring flange; the external ring comprises an external ring flange and an external ring conical hole, a side of the external ring flangeis fixedly connected with a side of the external ring conical hole, and external ring mounting holes and detaching threaded holes are formed in the external ring flange; the external ring conical hole can be arranged in internal splines of the speed reducers, the internal conical head and the shaft can be sequentially arranged in the external ring conical hole, and the internal ring mounting holes can be connected and fastened with the external ring mounting holes by bolts. The internal spline expansion sleeve structure has the advantages that the internal splines of the speed reducers can beconnected with the shaft by expansion sleeves, rotation of the internal splines of the speed reducers can be converted into rotation of the shaft, measurement on the machining precision of the internal splines can be converted into measurement on end surface jumping and seam allowance jumping of the speed reducers, accordingly, the internal spline expansion sleeve structure can bring conveniencefor measurement, is simple and is low in cost and convenient to detach and mount, and the measurement efficiency can be improved.

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...
