Description
Technical field
The present invention relates to oil seal spring technical field, and in particular to a kind of oil seal spring part for being easy to assembling.
Background technology
Oil sealing is that (oil is most common liquid substance in transmission system, also refers in general liquid substance for oil sealing fat
Meaning) mechanical organ, the part for needing to lubricate in transmission parts is isolated, is unlikely to allow lubricating oil to ooze by it with output part
Leakage.Static seal and dynamic sealing (general to move back and forth) are with seal seal.The representative form of oil sealing is TC oil sealings, and this is one
The two-lip seal with self-tightening spring that kind rubber coats completely, oil sealing generally often refer to this TC outside framework oil seals.
There is an annular spring on oil sealing, be exactly oil seal spring, effect is that oil sealing is stuck on axle, and sealing is tighter.
Existing oil seal spring is directly entered big opening end realization by osculum end when being attached and connected, outside osculum end
Footpath be equal to big opening end internal diameter, when being attached, due to spring surface and on-plane surface, and the intensity of oil seal spring in itself compared with
Greatly, deformation is not susceptible to, so its deformation restoring force is very big, and shakiness is fixed in the assembling structure connection end of existing oil seal spring
It is fixed, easily disassemble automatically, cause to need situation about assembling repeatedly when using.
The content of the invention

A kind of oil seal spring part for being easy to assembling, including spring part body, the spring part body upper end set connecting portion,
The connecting portion upper surface sets fixing end, and the upper surface of the fixing end sets circular arc chamfering；The circular arc of the circular arc chamfering
Elastic clipping strip is fixedly installed on face, the arc surface of the lateral surface of the elastic clipping strip and the circular arc chamfering is tangent；The spring
The internal diameter of part body is equal with the maximum outside diameter of the connecting portion, and the spring part body internal surface is set and the elastic clipping strip
The neck that lower end matches.
Further, the connecting portion lower end is connected with the spring part body upper surface arc transition, the spring
The lower surface of part body is set is connected the hatch frame to match with the arc transition.
Further, the elastic clipping strip is symmetrically set centered on the center line under the spring part body elongation state
Put, the spacing between the elastic clipping strip is equal.
Further, the maximum outside diameter of the fixing end is less than the external diameter of the connecting portion.
Further, the difference of the external diameter of the connecting portion and the maximum outside diameter of the fixing end and the elastic clipping strip
Thickness is equal.
Further, the minimum constructive height of the elastic clipping strip lower end is more than the height of the connecting portion upper surface, described
The material of elastic clipping strip is steel or the higher plastic of hardness.
Further, the distance of the neck and the spring part body lower surface be equal to the elastic clipping strip lower end with
The distance of the spring part body upper surface.
Beneficial effect
The invention provides a kind of oil seal spring part for being easy to assembling, compared with existing known technology, of the invention has
Following beneficial effect：
1st, smart structural design, it is easy to dismount.
2nd, it can effectively avoid what the automatic head and the tail connection end of oil seal spring was untied automatically in the presence of deformation restoring force
Situation, add the stability of oil seal spring assembling.
