Large-sized precision bearing radial play multifunctional automatic measurement method and measuring apparatus

Abstract

A multifunctional automatic measurement method for radial clearance of large-scaled precision bearing adopts static measurement, dynamic measurement and three-point measurement and is capable of automatically loading and automatically measuring. The three measurement manners can be implemented on one measuring apparatus at the same time. The measuring apparatus mainly comprises an electrical system (1), a measurement pedestal (2), a sensor support (3), a sensor adjusting nut (4), an inductive sensor (5), an upper cylinder support (6), an upper loading cylinder (7), a measurement shaft centre (9), a measurement main shaft (10), a lower loading cylinder (11), a lower cylinder support (12), a measurement support (13), a synchronous motor (14), a Hall element (15), a belt wheel and cog belt (16), a precise pressure regulating valve (17), and a precise pressure gauge (18). The measuring apparatus can provide reliable detection and analysis data for high-precise measurement of radial clearance of large-scaled precision bearings (8).

Description

technical field [0001] The invention belongs to the technical field of bearing measurement, and in particular relates to a multifunctional automatic measurement method and a measuring instrument for radial clearance of large precision bearings. Background technique [0002] In recent years, the domestic demand for high-precision bearings has increased in variety and quantity, and the radial clearance of large bearings has been strictly controlled. [0003] At present, the domestic market-oriented radial clearance measuring instruments for bearings with an inner diameter greater than 100mm mainly include the X095J radial clearance static measuring instrument, which has the following defects: [0004] 1. The purely mechanical static measurement cannot reflect the actual working state of the bearing, and causes errors due to the ball position. [0005] 2. The display mode is mechanical watch display, and the data processing is done manually, which has low efficiency, poor prec...

AI Technical Summary

Problems solved by technology

[0004] 1. Purely mechanical static measurement cannot reflect the actual working state of the bearing, and causes errors caused by the ball position

[0005] 2. The display mode is mechanical watch display, and the data processing is done manually, which has low efficiency, poor precision and large subjective error, so it cannot meet the measurement requirements of large precision bearings;

[0006] 3. Both loading and measurement are manual single-step operations, which are cumbersome, time-consuming, and prone to errors, and users require automatic loading and automatic measurement;

[0007] 4. The loading structure adopts a lever structure, which is prone to measurement errors caused by the non-parallel loading of the upper and lower levers.

[0008] 5. At present, the measurement methods of these instruments are single, and there is only one function of static measurement, and users often require static, dynamic and three-point measurement methods
