Description

A kind of sealing ring of the multiple sealed muscle of interior round belt

Technical field

This utility model relates to a kind of sealing ring, particularly relates to the sealing ring of a kind of multiple sealed muscle of interior round belt.

Background technology

The pure glue sealing ring of tradition that we are generally used on needle bearing at present, it is mainly used for sealing needle bearing internal grease and preventing the effect of muddy water, also require have good air-tightness to ease up compression functions simultaneously, but the sealing ring of traditional structure major downside is that inner circle is faced directly, when contacting with retainer, contact surface is big, cannot delay pressure when bearing pressure.

Summary of the invention

The purpose of this utility model is that the sealing ring providing a kind of multiple sealed muscle of interior round belt in order to solve the problems referred to above.

This utility model is achieved through the following technical solutions above-mentioned purpose:

This utility model includes rubber bodies, and described rubber bodies is hollow circular cylinder structure, and its inwall is provided with sealed muscle.

Specifically, described sealed muscle is at least one.

The beneficial effects of the utility model are in that:

This utility model adopts the sealing ring of the interior multiple sealed muscle of round belt, namely can guarantee that good air-tightness, can also well relax the pressure of Bearing inner, thus better protecting bearing simultaneously; This utility model has simple in construction, stable performance and service life longer advantage.

Accompanying drawing explanation

Fig. 1 is the sectional structure schematic diagram of the sealing ring of a kind of multiple sealed muscle of interior round belt described in the utility model;

Fig. 2 is the cross-sectional structure schematic diagram of the sealing ring of a kind of multiple sealed muscle of interior round belt described in the utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As depicted in figs. 1 and 2: this utility model includes rubber bodies 1, and rubber bodies 1 is hollow circular cylinder structure, and its inwall is provided with sealed muscle 2, and sealed muscle 2 is at least one.

In sum, this utility model devises multiple sealed muscle to reduce contact surface thus increasing the slow compression functions of sealing ring in the inner circle of sealing ring, improves the service life of bearing; This utility model has simple in construction, stable performance and service life longer advantage.

Those skilled in the art are without departing from essence of the present utility model and spirit, various deformation scheme can be had to realize this utility model, these are only the embodiment that this utility model is preferably feasible, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization this utility model description and accompanying drawing content are made, is both contained within interest field of the present utility model.

Claims

1. the sealing ring of the multiple sealed muscle of round belt in a kind, it is characterised in that: including rubber bodies, described rubber bodies is hollow circular cylinder structure, and its inwall is provided with sealed muscle.
