Abstract

The invention relates to the technical field of motor production, and discloses a measuring instrument for the keyway depth and symmetry of a motor shaft, which includes a dial. A curved bar, the right side of the bottom of the connecting curved bar is fixedly connected with a support rod, the bottom of the connecting curved bar is fixedly connected with a vertical sliding measurement base, and the front side of the vertical connecting block is fixedly connected with a horizontal sliding measuring base base. By rotating the rotating sleeve, the threaded rod of the graduated scale is driven to slide to the right, and then the measuring tool is driven into the double keyway, and the position data of the scale scale on the surface of the base is recorded when the horizontal sliding is measured at this time, and then connected to the curved rod by turning 180. From ten degrees to the double keyway on the opposite side, repeat the measurement process of the previous step to read the scale data on the surface of the horizontal sliding measurement base, and subtract the two data, so as to achieve the effect of precise positioning and rapid measurement.

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...
