Description
Technical field
The utility model relates to auto parts and components field, and particularly one follows rotating seal ring.
Background technique
See Fig. 1, at present, known rotating seal ring of following is made up of main body, skeleton, main cutting edge and secondary cutting edge, and wherein main cutting edge is connected with skeleton.After installation, main cutting edge is close to running shaft, reaches the effect of sealing.But, because the toughness of material of main cutting edge and skeleton is poor, easily cause main cutting edge flange during installation, seal bad.PTFE sheet is directly connected with skeleton, does not have followability; PTFE sheet is a monomer, does not have external force to shrink.After seal ring uses a period of time, main cutting edge material aging, cannot be close to running shaft, seal failure.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of flange problem can avoided when installing, and can solve the sealing problem after main cutting edge material aging simultaneously, and what extend the working life of seal ring follows rotating seal ring.Described technological scheme is as follows:
The utility model embodiment provides one and follows rotating seal ring, described in follow that rotating seal ring comprises external diameter R shape sealing strip, the metal frame be arranged in described external diameter R shape sealing strip two ends, by can deformation structure and the PTFE material be connected bottom described external diameter R shape sealing strip and the main cutting edge of rubber convolution, the rubber pair cutting edge that is connected with described external diameter R shape sealing strip top;
Described can deformation structure be PTFE material and rubber built up structure, for PTFE material and the main cutting edge of rubber convolution can be beated with running shaft and the deformation structure of following on the basis sealed.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:
Main cutting edge and skeleton are by can deformation structure be connected, main cutting edge can be made to follow deformation main body and to produce certain displacement, the active force making main cutting edge be adjacent to part is provided simultaneously, flange problem when installing can be avoided, the sealing problem after main cutting edge material aging can be solved simultaneously, extend the working life of seal ring.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of seal ring of the prior art;
Fig. 2 is the structural representation of following rotating seal ring that the utility model embodiment provides.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
Embodiment
The utility model embodiment provides one and follows rotating seal ring, see Fig. 2, described in follow that rotating seal ring comprises external diameter R shape sealing strip 1, the metal frame 2 be arranged in external diameter R shape sealing strip 1 two ends, by can deformation structure and the PTFE material be connected bottom external diameter R shape sealing strip 1 and the main cutting edge 3 of rubber convolution, the rubber pair cutting edge 4 that is connected with external diameter R shape sealing strip 1 top;
External diameter R shape sealing strip 1, plays the seal action of packing holder junction;
Metal frame 2 is arranged in external diameter R shape sealing strip 1, plays and supports seal ring effect;
PTFE material and the main cutting edge 3 of rubber convolution, play sealing rotary rotating shaft liquid effects; PTFE material is not directly connected with metal frame 2 with the main cutting edge 3 of rubber convolution;
The secondary cutting edge 4 of rubber, plays sealed external dust, impurity effect;
Can deformation structure be PTFE material and rubber built up structure, for PTFE material and the main cutting edge 3 of rubber convolution can be beated with running shaft and the deformation structure of following on the basis sealed;
This can deformation structure PTFE material and the main cutting edge of rubber convolution 3 stressed time, can deformation, and can reaction force be provided; When seal ring is installed, utilizes frock to strut seal ring PTFE material and the main cutting edge 3 of rubber convolution, make diameter of bore be greater than shaft diameter, avoid flange; When after PTFE material and rubber convolution main cutting edge 3 material aging, the agent structure of energy deformation can provide certain active force, makes PTFE material and the main cutting edge 3 of rubber convolution be close to running shaft, plays seal action.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:
Main cutting edge and skeleton are by can deformation structure be connected, main cutting edge can be made to follow deformation main body and to produce certain displacement, the active force making main cutting edge be adjacent to part is provided simultaneously, flange problem when installing can be avoided, the sealing problem after main cutting edge material aging can be solved simultaneously, extend the working life of seal ring.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
