Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.
To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.
Referring to fig. 1 to 6, in the present embodiment, there is provided a wear-resistant rubber sealing ring for a vehicle, including: the rubber sealing ring comprises a sealing ring body 1, wherein one end of the sealing ring body 1 is provided with a rubber bulge 2, and the other end of the sealing ring body 1 is provided with a wear-resistant layer 3;
the outer side wall of the sealing ring body 1 is provided with a first concave surface 4, a second concave surface 5 positioned on one side of the first concave surface 4 and a first end surface 6 positioned on one side of the second concave surface 5;
the seal ring body 1 is provided with an embedded convex part 9.
When the sealing ring body 1 needs to be used, the sealing ring body 1 needs to be placed between the driving shaft and the installation shell for fixing, and then the sealing performance between the driving shaft and the installation shell is improved.
Since the fluid to be sealed is introduced into the groove portion, the fluid pressure acting on the seal ring from the high pressure side and the fluid pressure acting on the seal ring from the low pressure side cancel each other out in the range where the groove portion is provided, whereby the pressure receiving area of the seal ring on which the fluid pressure acts can be reduced, and when the seal ring slides against the side wall surface on the low pressure side in the annular groove, the fluid to be sealed flows out from the dynamic pressure generating groove to the sliding portion to generate dynamic pressure, whereby a force in a direction of separating the seal ring from the side wall surface is generated, and further, since the groove bottom of the dynamic pressure generating groove is formed so that the circumferential end portion is shallower than the circumferential center, the dynamic pressure can be effectively generated by the wedge effect, the pressure receiving area reduction and the force in the direction of separating the seal ring from the side wall surface due to the dynamic pressure generate each other, and the rotational torque can be effectively reduced.
Specifically, a first groove 8 is formed in the sealing ring body 1, and a second groove 7 is formed in the sealing ring body 1.
Specifically, and second recess 7 is linked together with first recess 8, and wearing layer 3 includes: the surface of the vulcanized rubber layer is connected with a polybutadiene rubber layer in an adhesive mode, the surface of the polybutadiene rubber layer is connected with a styrene-butadiene rubber layer in an adhesive mode, a second end face 10 is arranged on the sealing ring body 1, and the second end face 10 is located on one side of the rubber protrusion 2.
