Measuring tool and method used for measuring height from end surface of conical bearing outer ring to joint surface

Abstract

The invention provides a measuring tool and a method used for measuring the height from the end surface of a conical bearing outer ring to the joint surface, belonging to the technical field of machinery, and solving the problem that various measuring errors exist due to the adoption of the existing manual prototype engine measuring device and method used for measuring. The measuring tool used for measuring the height from the end surface of the conical bearing outer ring to the joint surface of a speed changer comprises a compacting piece and a positioning bracket, wherein the compacting piece props against the end surface of the conical bearing outer ring, the positioning bracket is capable of positioning on the joint surface of a front shell of the speed changer, a force application mechanism capable of enabling the compacting piece to apply axial pre-tightening force on the end surface of the conical bearing outer ring is arranged between the positioning bracket, and a measuring assembly capable of measuring the height from the end surface of the conical bearing outer ring to the joint surface is arranged on the positioning bracket. Due to the adoption of the measuring method, the measuring data is accurate and scientific, and the measuring tool has the advantages of simple structure, convenience in use, stable performance and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a measuring tool, in particular to a measuring tool used for measuring the height from the end surface of the outer ring of the transmission tapered bearing to the joint surface. [0002] The invention also belongs to the technical field of measurement, and relates to a measurement method, in particular to a method for measuring the height from the end surface of the outer ring of the transmission tapered bearing to the joint surface by using a measuring tool for measuring the height from the end surface of the outer ring of the transmission tapered bearing to the joint surface. Background technique [0003] During the assembly process of the transmission, it is necessary to measure the height from the end surface of the outer ring of the tapered bearing on the transmission shaft assembly to the joint surface of the front and rear housings in order to calculate the thickness of ...

AI Technical Summary

Problems solved by technology

Whether the thickness of the tapered bearing gasket is selected correctly is related to the transmission efficiency of the transmission assembly in the process of power transmission. If the gasket is too thick, the axial movement of the transmission shaft will be reduced, which will cause the transmission to heat at the bearing and cause the transmission to be damaged. ; If the gasket is too thin, the axial movement of the transmission shaft will increase, the noise will increase, and the service life of the transmission will be reduced

[0004] The current manual prototype measuring devices and methods include the use of a height measuring device and a three-coordinate meter for measurement. When using the above-mentioned device and method for measurement, there are the following measurement errors: ①The height of the outer ring of the taper bearing on the transmission shaft from the joint surface is too large , the transmission shaft swings during the measurement, resulting in deflection, resulting in inaccurate measurement results; ②When measuring the tapered bearing, no preload is added to the outer ring of the tapered bearing, resulting in a large measurement height; ③When measuring, the measured data is static Measurement, cannot guarantee that all parts are in place, resulting in deviation of measurement results
