Abstract
The utility model belongs to the technical field of bearing clutches, and provides a clutch bearing sealing ring which solves the problems that an existing clutch bearing sealing ring is too simple in structure, and therefore the sealing effect is not good. The clutch bearing sealing ring comprises a rigid framework and a flexible rubber sealing ring body wrapping the outer surface of the rigid framework, an inner sealing lip and an outer sealing lip are arranged on the right side face of the sealing ring body, and the outer sealing lip is formed in the mode that a flanging facing the right side of the sealing ring body is arranged at the inner end of the sealing ring body. The clutch bearing sealing ring has the advantages that grease is effectively prevented from leaking outwards along the outer diameter of an inner ring, and the outer sealing lip prevents grease from leaking in the radial direction and dirt from seeping inwards, and the sealing effect is improved.
Description
Technical field
The utility model belongs to bearing clutch technical field, refers in particular to a kind of clutch seal ring.
Background technique
At present, the structure of existing clutch bearing seal ring is comparatively simple, is only provided with the seal lip at outside diameter of inner ring, and the end face side of seal ring and interior ring does not have structure of sealing lip, easily produces the phenomenon that grease is revealed.
Summary of the invention
The purpose of this utility model is to provide a kind of clutch seal ring, and it has played and has prevented that grease from leaking, the effect that sealability is better.
The purpose of this utility model is achieved in that
A kind of clutch seal ring, comprise rigid backbone and the flexible rubber sealing circle body that is coated on rigid backbone outer surface, it is characterized in that: the right flank of described sealing circle body is provided with an interior seal lip and external sealed lip, described external sealed lip is: the inner of sealing circle body is provided with the flange towards sealing circle body right side.
In above-mentioned a kind of clutch seal ring, the sectional shape of described interior seal lip is triangular in shape, and main rising stops that grease is along outside diameter of inner ring to outward leakage; The sectional shape of described external sealed lip is rectangular, is fitted in interior ring step end face and deadens grease radially seepage and dirt Inner ooze.
The utility model compared to existing technology outstanding and useful technique effect is:
The utility model is the inner at seal ring, is provided with two seal lips with the contact jaw of interior ring, has effectively prevented leaking of grease.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use phase diagram of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:
A kind of clutch seal ring, comprise rigid backbone 1 and the flexible rubber sealing circle body 2 that is coated on rigid backbone outer surface, the right flank of described sealing circle body is provided with an interior seal lip 5 and external sealed lip, and described external sealed lip is: the inner 3 of sealing circle body is provided with the flange 4 towards sealing circle body right side.
The sectional shape of above-mentioned interior seal lip 5 is triangular in shape, and the sectional shape of described external sealed lip is rectangular.Wherein main the rising of interior seal lip 5 stops that grease is along outside diameter of inner ring to outward leakage, and 4 of external sealed lips are fitted in interior ring step end face and deaden grease radially seepage and dirt Inner ooze
As shown in Figure 2, in prior art structure, flange 4 is non-existent, relies on the interior edge face of seal ring to contact sealing with the outer side surface of ring in clutch, in actual use, exist gap to make inner grease spill between the two, thereby make clutch surface dirty, internal lubrication deficiency, in this structure, be provided with flange 4, by forming a refluxing chamber between interior seal lip 5 and flange 4, grease is difficult for revealing, and the sealability of entirety is good.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
Claims (2)
1. a clutch seal ring, comprise rigid backbone (1) and be coated on the flexible rubber sealing circle body (2) of rigid backbone outer surface, it is characterized in that: the right flank of described sealing circle body is provided with an interior seal lip (5) and external sealed lip, described external sealed lip is: the inner (3) of sealing circle body is provided with the flange (4) towards sealing circle body right side.
2. a kind of clutch seal ring according to claim 1, is characterized in that: the sectional shape of described interior seal lip (5) is triangular in shape, and the sectional shape of described external sealed lip is rectangular.
