Measuring device for angular contact ball bearing outer ring hold depth and measuring method thereof

Abstract

The invention discloses a measuring device for the angular contact ball bearing outer ring hold depth and a measuring method thereof. The measuring device for the angular contact ball bearing outer ring hold depth mainly comprises a measuring platform, a pressing rod post (4), a pressing rod (6), a torque spring meter (1), a lever, an upright post (9) and a fixing block (11), wherein one side of the upper end of the lever (14) is provided with a measuring support rod used for being in contact with the groove bottom measuring fulcrum of a loop ring to be measured, and one side of the fixing block is provided with a fixed support rod which is used for being in contact with the locking point of the loop ring to be measured, i.e. the fixed fulcrum. The measuring method for the angular contactball bearing outer ring hold depth comprises the following steps of: A, selecting and detecting angular contact ball bearing outer ring hold depth standard elements; B, regulating the measuring device; C, setting the meter; and D, carrying out the measurement. The measuring device and the measuring method have the advantages that the operation process is simplified, the measurement cost is reduced, simultaneously, the measurement precision is also improved, the measurement error is reduced.

Description

technical field [0001] The invention belongs to a method for measuring the outer ring of a bearing, and mainly designs a method for comparing the locking amount of the outer ring of an angular contact ball bearing. Background technique [0002] The structural characteristics of the outer ring of the angular contact ball bearing are as attached figure 1 As shown, the slope 17 intersects the channel 18 at the locking point 19, and the locking amount f e Refers to the radial distance from the locking point 19 to the bottom 20 of the channel. The size of the lock will affect the assembly process of the bearing and must be controlled. In the bearing industry, the current lock volume f e There are three commonly used detection and control methods, but all of them have different degrees of defects. Details are as follows: [0003] Method 1: Use D724B tapered roller bearing inner ring raceway diameter and angle measuring instrument (used to measure bearing inner ring raceway di...

AI Technical Summary

Problems solved by technology

However, it is limited by the slope angle tolerance, and the measurement error is large, which cannot meet the requirements; the measurement force is large, and it is easy to scratch the surface of the groove; the structure of the D714 instrument is complex, and the adjustment time is long; the D714 instrument is a special instrument for measuring roller bearings and the price is relatively high. High, the ball bearing factory is not equipped with this instrument
