Problems solved by technology

[0002] Due to the quality of the rubber used in my country's current sealing rings is not good enough, after the bearing sealing ring is installed, the rebound strength of the sealing lip is not enough, resulting in the problem of reverse lip or discount after the sealing ring is installed, so that the sealing effect cannot be achieved, so It is necessary to study and improve the structure of the sealing ring

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] A new type of bearing sealing ring, including a non-installed rubber sealing lip 1, a steel skeleton 2, and an installed rubber sealing lip. The sealing ring removes the unloading groove, increases the thickness H of the rebound rubber, and increases the rebound strength by 1.5 to 2 times. The sealing ring of the present invention has no unloading groove structure, so that the resilience strength is increased, and the sealing ring is not easy to have the phenomenon of anti-lip and discount.

[0012] The bearing sealing ring of the present invention removes the original unloading groove, the design of the production mold of the sealing ring is relatively simple, and the operability of its production is relatively easier than that of the traditional sealing ring.

Abstract

The invention relates to the technical field of bearing seal ring design, in particular to a novel bearing seal ring. The novel bearing seal ring comprises a non-mounted rubber sealing lip, a steel skeleton and a mounted rubber sealing lip, an unloading groove is removed from the sealing ring, the thickness H of rebound rubber is increased, the rebound strength is increased by 1.5 to 2 times. According to the novel bearing seal ring, the problem of lip reversing or breakage after an existing sealing ring is mounted is relieved greatly, the remedial effect on the unqualified quality of rubber adopted by a current seal ring in China is achieved, the production cost is lower, and the sealing effect is good.

Description

technical field [0001] The invention relates to the technical field of bearing seal ring design, in particular to a novel bearing seal ring. Background technique [0002] Due to the quality of the rubber used in my country's current sealing rings is not good enough, after the bearing sealing ring is installed, the rebound strength of the sealing lip is not enough, resulting in the problem of reverse lip or discount after the sealing ring is installed, so that the sealing effect cannot be achieved, so It is necessary to study and improve the structure of the sealing ring. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a new type of bearing sealing ring. [0004] In order to realize the above-mentioned purpose of the invention, the present invention adopts the following technical solutions: [0005] A new type of bearing sealing ring, including a non-installed rubber sealing lip, a steel skeleton, and an ins...
