Description

Just, pressure formula clutch bearing sealing washer

Technical Field

The utility model relates to a just, press formula clutch bearing seal circle belongs to the bearing seal circle field.

Background

Just, pressure formula clutch is as the spare part commonly used in mechanical engineering, and wherein also very important to the sealed of bearing, need establish the sealing washer at bearing outer lane cover for sealed, the sealing washer need guarantee stable assembly outside the bearing, and do not influence the use of bearing, traditional sealing washer external diameter assembles for the mode assembly that the punching press extrusion produced deformation, does not consider that sealing washer assembly punching press leads to the bearing outer lane to warp, thereby influences the installation use of bearing.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a just, press formula clutch bearing sealing washer can effectively solve current bearing installation and lead to the bearing to produce the problem of deformation easily.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

a convenient-to-press type clutch bearing sealing ring is arranged on an outer ring of a bearing and comprises a supporting framework; the sealing assembly is arranged on the supporting framework; wherein, seal assembly includes outer lip and interior lip, be equipped with the opening along the circumference equipartition on the outer lip, the opening both sides are equipped with the flanging of outside extension, be the acute angle between flanging and the vertical axis, the flanging top with bearing inner race joint utilizes the elasticity flanging and the bearing inner race bottom joint of opening formation both sides, and the installation rate is faster to can not influence the normal work of bearing, can not produce deformation.

Preferably, the angle between the outward flange and the vertical axis ranges from 15 degrees to 25 degrees, and the outward flange can be more easily clamped on the bearing outer ring and cannot fall off.

Preferably, an acute angle is formed between the inner lip and the horizontal axis, so that the inner lip is more favorably attached to a part, the sealing stability is improved, and leakage is not easy to generate.

Furthermore, a plurality of sealing lips which are abutted to the bearing are distributed on the bottom of the inner lip part, so that the sealing performance of the sealing ring can be improved, the pollution in the external environment is isolated, and the bearing can normally work.

Preferably, the material of support skeleton is elastic skeleton material, and the flexible cover of sealing washer of being convenient for is established outside the bearing and is sealed to can not influence the bearing, produce deformation.

Preferably, the material of inner lip is rubber, seals the bearing, and the shape of laminating spare part increases the leakproofness of sealing washer.

Compared with the prior art, the utility model has the advantages that:

improve support chassis and be elasticity skeleton material to set up the opening and the flanging of lip portion, reduce the assembly degree of difficulty of sealing washer and bearing inner race, establish to the acute angle between flanging and the perpendicular axis, more stable installs outside the bearing inner race, avoids the bearing to produce deformation, influences normal use.
