Example Embodiment

[0024] like figure 1 and image 3 , a method for detecting the shape of a sealed bearing sealing structure disclosed in the present invention is carried out according to the following steps:

[0025] (1) Sample preparation, a. Mix and stir the liquid resin and its curing agent evenly to form a flowable paste mosaic; the mosaic can choose "Crystal King" CM2, which can be purchased directly in the market, such as Naibo Other similar mosaic materials, such as "Crystal King" CM1, "Quick Epoxy King" CM3, etc., can also be used for those produced by Detection Technology (Shanghai) Co., Ltd.

[0026] b. Put the sealed bearing 2 in the mold cavity of the mosaic mold 1, pour the mosaic material into the mold cavity of the mosaic mold 1, and the mosaic material wraps the bearing evenly by its own fluidity until it completely covers the bearing; and solidifies ; In order to facilitate demoulding after curing, the mosaic mold 1 is a barrel-shaped structure made of soft rubber (such as s...

Abstract

The invention relates to a sealed bearing sealing structure shape detection method. An inlaid material is inlaid and solidified. The cross section is exposed through axial half-cutting. The mosaic material is polished and placed on a projection device for projection to acquire a CAD image. The invention further provides a sealing ring shape detection method. Axial half-cutting is carried out to form the cross section. The cross section is controlled to be fixed in an inlay mold. The inlay material is poured, inlaid, solidified and polished to acquire a sample. The sample is placed on the projection device. The cross section is projected to acquire the CAD image. According to the invention, a bearing sealing structure and a sealing ring structure can be directly recorded and observed, and the methods have the advantages of simple operation and convenient size and wear detection.

Description

technical field [0001] The invention relates to a shape detection method, specifically a sealing structure of a sealed bearing and a shape detection method of a sealing ring thereof. Background technique [0002] The sealing performance of the bearing is guaranteed by the sealing ring and the corresponding sealing structure. The existing test for the sealing performance of the bearing is to pass through the medium and observe its leakage. When it is necessary to accurately observe the sealing ring, the cooperation between the lip body of the sealing ring and the shaft ring, the size and wear of the sealing ring, the existing detection methods cannot meet the requirements. The dimensions of the bearing sealing ring cannot be well detected, and the wear of the rubber lip of the bearing sealing ring does not need to be accurately detected and analyzed. Contents of the invention [0003] Purpose of the present invention: In order to overcome the defects of the prior art, the ...
