Coupling height measuring scale

Abstract

The invention discloses a coupling height measuring scale and relates to the measuring technology field. The measuring scale comprises a pedestal which is provided with a gauge stand hole. The gauge stand hole is provided with a gauge stand, a copper sleeve is arranged in the gauge stand, and a digital display dial indicator is arranged in the copper sleeve and is fixed by a set screw. A lower endof the pedestal is set to be a measured protruding platform, and a side surface of an upper end is provided with an overlapping curve. The side surface of the copper sleeve is provided with a throughgroove with a width of 1 mm. Problems that when commonly used measuring tools, such as a depth gauge and a dial indicator, are used to measure a distance value between an end surface of shaft bossingof the coupling and the end surface of a motor main shaft, measurement is difficult, an error is large and efficiency is low due to a condition limit of a measuring part can be solved.

Description

technical field

[0001] The invention relates to the technical field of measurement, in particular to a measuring tool for measuring the distance values ​​from the end faces of shaft hubs of various types of couplings to the end faces of motor main shafts. Background technique

[0002] During the assembly process of the coupling shaft and the coupling hub, install various types of couplings as a whole on the shaft with a taper of 1:50, and gently push the couplings along the axial direction to make the coupling shaft The inner hole of the hub (taper 1:50) is attached to the motor shaft (or the pinion shaft of the gearbox) to complete the assembly, such as figure 1 As shown, after the assembly is completed, it is necessary to measure the end face of the motor shaft, that is, the distance A1 from the measurement surface S1 to the measurement reference surface (base positioning surface) S3, and the step surface of the coupling hub, that is, the measurement surface S2 to the meas...
