Sealing ring framework structure of ultra-thin-wall bearing with uniform section

Abstract

The invention relates to a sealing ring framework structure of an ultra-thin-wall bearing with a uniform section. The sealing ring framework structure comprises a sealing ring and a framework, wherein toothed grooves are symmetrically formed in two sides of the inner surface of an outer ring of the ultra-thin-wall bearing with the uniform section, steps are symmetrically arranged on two sides of the outer surface of an inner ring of the ultra-thin-wall bearing with the uniform section, the sealing ring is arranged between the toothed groove of the outer ring of the ultra-thin-wall bearing with the uniform section and the step of the inner ring of the ultra-thin-wall bearing with the uniform section, is in interference fitting with the toothed groove of the outer ring and is in radial contact with the step of the inner ring, so as to achieve the sealing effect; the framework is of a sheet-like hollow cylinder spring steel structure with a rectangular cross section shape; and the sealing ring covers the outside of the framework. The sealing ring framework structure is simple and compact in structure, small in spatial size, high in strength, good in bearing sealing effect and good in revolving flexibility of the bearing.

Description

technical field [0001] The invention belongs to the technical field of bearing design, and in particular relates to a skeleton structure of a sealing ring of an equal-section ultra-thin-walled bearing. Background technique [0002] According to different practical working conditions, the bearing can be used in two types: open type and closed type. In the closed type bearing, two types of sealing types, contact type and non-contact type, can be selected. For the contact type seal, we used the seal of the most famous international brand KAYDON in the past. The cross-sectional shape of the ring is a "7"-shaped skeleton to increase strength (such as Figure 1A and Figure 1B shown). Due to the compact structure and limited space of the equal-section ultra-thin-wall bearings, the "7" shape of the skeleton takes up a large space, and because the skeleton material is carbon steel, the sealing ring will be warped when manufacturing, handling and loading and unloading the sealing ri...

Problems solved by technology

Due to the compact structure and limited space of the equal-section ultra-thin-walled bearing, the "7" shape of the skeleton takes up a large space, and because the skeleton material is carbon steel, the sealing ring will be warped when manufacturing, handling and loading and unloading the sealing ring. Warp deformation, or even scrapped, and need to replace a new sealing ring

[0003] It can be seen that the above-mentioned existing seal ring skeleton structure of the equal-section ultra-thin-walled bearing obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned existing problems, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time. This is obviously a problem that relevant manufacturers are eager to solve.
