Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, the present invention provides a method for measuring the size of a bearing sealing ring, comprising the following steps:

[0025] (1) Use a video measuring instrument to measure the inner diameter and outer diameter of the bearing seal ring. Of course, other devices can also be used to measure the inner diameter and outer diameter, such as a tool microscope.

[0026] (2) if figure 2 As shown, cut a small measuring sample with a length of 15mm along the radial direction of the sealing ring. When cutting, the skeleton of the sealing ring cannot be deformed, and the cut must be smooth. The cross-sectional view of the measurement sample is as image 3 shown.

[0027] In the present invention, the length of the measurement sample is preferably 10-20 mm, and of course it can be smaller or larger, as ...

Abstract

The invention provides a method for measuring the size of a bearing sealing ring. The method comprises the following steps of: (1) measuring the sizes of an inner diameter and an outer diameter of the bearing sealing ring; (2) cutting a small section of measurement sample down along the radial direction of the sealing ring; (3) fixing the measurement sample, and detecting the size of the measurement sample under an image measurer; and (4) combining the sizes of the inner diameter, the outer diameter and the measurement sample of the bearing sealing ring, and thus obtaining the size of the sealing ring. According to the method, the sizes of the inner diameter and the outer diameter of the bearing sealing ring are measured at first; then the measurement sample is cut along the radial direction of the sealing ring; the sizes of a lip structure and the like with complicated shapes are measured by the image measurer; and finally, the sizes are combined to obtain the whole size of the sealing ring. The method is simple and feasible, realizes that the bearing sealing ring which has a complicated structure and a small measurement space and is made of a soft material can be measured effectively; and reliable support is supplied for guaranteeing the sealing effect of the bearing sealing ring.

Description

technical field [0001] The invention belongs to the field of bearing detection, and in particular relates to a method for measuring the size of a bearing sealing ring. Background technique [0002] The size of the bearing sealing ring is a key factor to ensure the sealing effect of the bearing. At present, the shape of the bearing sealing ring is basically circular, with a metal skeleton inside, and the cross-section includes one or more lips of different shapes. Due to the complex structure of the lip, small measurement space, and soft material, it is difficult to measure it once it is processed. After use, the lip is partially worn and deformed, making it impossible to measure. At present, there is no detection equipment and detection method in the industry to detect it. Contents of the invention [0003] The invention provides a method for measuring the size of the bearing sealing ring aiming at the above-mentioned deficiencies in the prior art, which realizes the a...
