specific Embodiment approach 1

[0024] Specific implementation mode 1: Combination figure 1 To illustrate this embodiment, the method for measuring the position of the outer ring groove of a squirrel cage ball bearing described in this embodiment includes the following steps:

[0025] Step 1: Select a measuring instrument: According to the size of the bearing structure, use the D012 or D013 bearing special measuring instrument to measure the position and accuracy of the groove center 1 to the non-reference end surface 3, and use the G904 or G905 bearing special measuring instrument to measure the total bearing outer ring For the size of height H, select an instrument that meets the measurement accuracy according to the accuracy requirements;

[0026] Step 2: Measure the total height of the outer ring of the bearing: use the selected special measuring instrument to measure the distance between the reference end surface 2 and the non-reference end surface 3 of the bearing, that is, the total height H of the outer r...

specific Embodiment approach 2

[0032] Specific implementation manner two: combination figure 1 To explain this embodiment, in step 2 of this embodiment, when the height h between the channel center 1 and the reference end surface 2 is qualified, the tolerance of the total height H of the outer ring of the bearing needs to be measured, and it is performed in step 4 When calculating the height h between the channel center 1 and the reference end surface 2, the tolerance of the total height H of the outer ring of the bearing is included in formula 1. The technical features not disclosed in this embodiment are the same as those in the first embodiment.

[0033] For the first product that is qualified to be processed, the standard true value of the height h1 between the channel center 1 and the non-reference end surface 3 is obtained as a standard part by the method of the first embodiment, and the subsequent processing product is between the channel center 1 and the reference end surface 2 The height h of the spa...

specific Embodiment approach 3

[0036] Specific implementation mode three: combination figure 1 To explain this embodiment, the tolerance range of the total height H of the outer ring of the bearing in this embodiment is controlled within 0.004 mm. The technical features not disclosed in this embodiment are the same as those in the second embodiment.

[0037] The smaller the tolerance range of the total height H of the outer ring of the bearing, the better. This design facilitates the control of the dimensional difference between the channel center 1 and the reference end surface 2.

Abstract

The invention provides a measuring method for squirrel cage elastic support ball bearing outer ring groove position and precision, relates to the measuring method, and aims at solving problems that existing squirrel cage elastic support ball bearings cannot realize measurement of groove size and precision by using an original measurement technology. The measuring method for the squirrel cage elastic support ball bearing outer ring groove position comprises the steps that a measuring instrument is selected; total height of a bearing outer ring is measured; height h1 of the center of a groove and an unreference end surface is measured; and high h of the center of the groove and a reference end surface is calculated. The measuring method for squirrel cage elastic support ball bearing outer ring groove precision comprises measurement of runout of the center of the groove to the reference end surface. The measuring method is used for measurement of the squirrel cage elastic support ball bearing.

Description

Technical field [0001] The invention relates to a measuring method, in particular to a measuring method for the position and accuracy of the outer ring groove of a squirrel cage ball bearing. Background technique [0002] The squirrel-cage spring-supported ball bearing is a new structural bearing that integrates the spring-supporting system and rolling bearing developed in the past two years. The outer ring of the squirrel-cage spring-supported ball bearing has a special structure. Because the reference end face is on the side of the flange end The position of the reference end surface is long. The original measurement technology is limited by the structure of the special measuring instrument. It is impossible to measure with the elongated measuring ball point. The conventional measurement method cannot achieve the channel position size and the channel center to the reference end surface. Measurement of jitter. Summary of the invention [0003] In order to solve the problem that ...
