Abstract

The utility model belongs to the technical field of bearings, and provides a bearing sealing structure. The bearing sealing structure is provided with an annular sealing ring (2) which is arranged between a combined part of an outer bearing ring (1) and an inner bearing ring (3); the outer surface of an annular sealing ring body (6) is provided with a plurality of teeth (4); a fin (5) which extends outside is arranged on the annular sealing ring body (6); a sealing groove is formed in the inner bearing ring (3); the annular sealing ring body (6) is embedded into the sealing groove of the inner bearing ring (3); the fin (5) props against one end surface of the outer bearing ring (1). Thus, the bearing sealing structure is formed. The bearing sealing structure is used for improving the sealing degree between the inner bearing ring (3) and the outer bearing ring (1).

Description

A kind of sealing configuration of bearing

Technical field

The utility model belongs to technical field of bearings, relates generally to a kind of sealing configuration of bearing.

Background technique

Bearing is the supporting member in mechanical transmission mechanism, and for determining running shaft and other part relative movement position, its quality directly affects the service behaviour of mechanical complete machine, drives the motion of associated mechanisms by the running of bearing.Bearing turns round in various environment, rugged environment (as: dust storm, water, oil, salt fog etc.) particularly, and foreign matter is easy to enter raceway by the gap between the inside and outside circle of bearing, makes bearing on-stream destroyed.In order to address the above problem, sealing mechanism need to be set and prevent that bearing internal structure is destroyed, avoid bearing at oil starvation and foreign matter, to enter running under the state of raceway and use, but the problems such as that sealing mechanism of the prior art all exists is poorly sealed, easy leakage of oil.In addition, the sealing block in sealing mechanism easily comes off and sealing block is easily wound around other structures, causes sealing mechanism to damage.

Model utility content

For solving the problems of the technologies described above, the purpose of this utility model is the sealing configuration that proposes a kind of bearing.

The utility model adopts following technological scheme for completing foregoing invention object:

A sealing configuration for bearing, arranges an O-ring seal; Described O-ring seal is arranged on the binding site of bearing outer ring and bearing inner race; The outer surface of O-ring seal body has some teeth, on described O-ring seal body, has outwardly directed fin; On described bearing inner race, there is seal groove; Described O-ring seal body embeds in the described seal groove of bearing inner race, and described fin is overlapped on the end face of bearing outer ring, forms the sealing configuration of described bearing.

Described teeth on described O-ring seal body, fin and the described O-ring seal body structure that is formed in one.

The sealing configuration of a kind of bearing the utility model proposes, has improved the seal degree of bearing inner race, bearing outer ring.

In figure: 1, bearing outer ring, 2, O-ring seal, 3, bearing inner race, 4, teeth, 5, fin, 6, O-ring seal body.

Embodiment

With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:

As shown in Figure 1, a kind of sealing configuration of bearing, arranges an O-ring seal 2, and described O-ring seal 2 is arranged on the binding site of bearing outer ring 1 and bearing inner race 3; With reference to Fig. 2, the outer surface of O-ring seal body 6 has some teeth 4; On described O-ring seal body 6, there is outwardly directed fin 5, on described bearing inner race 3, there is seal groove; Described O-ring seal body 6 embeds in the described seal groove of bearing inner race 3, and described fin 5 is overlapped on the end face of bearing outer ring 1, forms the sealing configuration of described bearing.Described teeth 4 on O-ring seal body, fin 5 and described O-ring seal body 6 structure that is formed in one.

Claims

1. a sealing configuration for bearing, arranges an O-ring seal (2); Described O-ring seal (2) is arranged on the binding site of bearing outer ring (1) and bearing inner race (3); It is characterized in that: the outer surface of O-ring seal body (6) has some teeth (4); On described O-ring seal body (6), have outwardly directed fin (5), described bearing inner race has seal groove on (3); Described O-ring seal body (6) embeds in the described seal groove of bearing inner race (3), and described fin (5) is overlapped on the end face of bearing outer ring (1), forms the sealing configuration of described bearing.

2. a kind of sealing configuration of bearing according to claim 1, is characterized in that: the described teeth (4) on described O-ring seal body (6), fin (5) and described O-ring seal body (6) structure that is formed in one.
