Abstract

The invention relates to the technical field of motor production, and discloses a motor rotating shaft keyway depth and symmetry degree measuring instrument, which comprises a dial; a rotating slidinggroove is formed in the middle of the dial; a connecting bent rod is fixedly connected to the left side of the connecting base; a supporting rod is fixedly connected to the right side of the bottom of the connecting bent rod; a vertical sliding measurement base is fixedly connected to the bottom of the connecting bent rod; and a horizontal sliding measurement base is fixedly connected to the front side of the vertical connecting block. A graduated scale threaded rod is driven to slide rightwards by rotating a rotating sleeve; further, a measuring mold is driven to extend into a double-key groove, and the position data of the graduated scale on the surface of a horizontal sliding measurement base at the moment is recorded; the connecting bent rod is rotated by 180 degrees to the outside ofthe double-key groove on the opposite side, the previous measurement process is repeated to read the data of the graduated scale on the surface of the horizontal sliding measurement base, and the twopieces of data is subtracted, so that the effect of accurate positioning and rapid measurement is achieved.

Description

technical field [0001] The invention relates to the technical field of motor production, in particular to an instrument for measuring the depth and symmetry of a keyway of a motor shaft. Background technique [0002] The flat key connection is a common connection method in the motor assembly process, which is used to realize the circumferential fixation between the shaft and the parts on the shaft to transmit torque. The double-key connection is to distribute a key connection on both sides of the inner hole of the connection and the centerline of the shaft at a distance of 180 degrees. The double-key connection effectively reduces the pressure on a single key, can transmit greater torque, and improves key lifespan. The two sides of the keyway in the inner hole are the main working planes of the key joint, and its symmetry relative to the centerline of the inner hole is one of the main technical parameters of the keyway. If the symmetry of the keyway in the inner hole is ou...
