Novel sealing piece

Abstract

The invention discloses a novel sealing piece comprising a support ring frame and an annular sealing ring, wherein an annular groove is arranged along the inner wall surface of the support ring frame, a side rib, connected with the annular groove in a clamping way, is arranged in the middle of the outer side surface of the annular sealing ring, the upper end and the lower end of the annular sealing ring respectively extend out of the upper end surface and the lower end surface of the support ring frame, and the a plurality of flange ears are arranged at the outer side surface of the support ring frame in a surrounding way. For the sealing piece, the annular sealing ring is matched with the support ring frame, and when a shell is fastened, due to the protection function of the support ring frame, the sealing ring can be prevented from being damaged by expansion as being pressed tightly, therefore, the sealing stability of the sealing piece is ensured; in installing the sealing piece, as the sealing ring is fixed by the support ring frame, the installation can be more convenient, and the sealing ring can not shift; and with the structure, the service life of the sealing piece can be prolonged, and the sealing piece is convenient to replace.

Description

Technical field [0001] The present invention relates to seals. Background technique [0002] In gearboxes, pistons, cylinders and other products, the sealing performance between the shells is one of the important conditions to ensure the normal operation of the product. The existing structure usually sets a sealing ring groove between the shells and then installs the sealing ring to seal The disadvantage is that it is troublesome to turn the sealing ring into the embedded groove, and it is easy to jump out; another common structure is to directly install a flat sealing ring on the joint end of the shell to achieve sealing. The disadvantage is that the sealing member is easy to be It is also prone to offset due to bulging, which affects the sealing performance. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of sealing element, which has a simple structure, can prevent the fastening force from being swollen due...

Problems solved by technology

[0002] In various products such as gearboxes, pistons, and oil cylinders, the sealing performance between the shells is one of the important conditions to ensure the normal operation of the products. In the existing structure, sealing rings are usually installed between the shells and then the sealing rings are installed for sealing. , its shortcoming is that it is troublesome to turn the sealing ring into the embedded groove, and it is easy to jump out; another common structure is to directly install a flat sealing ring on the joint end face of the shell to achieve sealing, and its shortcoming is that the sealing is easy to be damaged when the connection is too tight. It is also prone to deflection, which will affect the sealing performance
