Abstract
The utility model discloses a kind of automobile belt wheel bearing seal ring, comprise body, end, be located at intrinsic skeleton, connect the waist of body and end, bearing inner race, it is characterized in that described body is provided with near waist end the gear oil lip tilted to body, the main lip tilted to body is provided with below described end, dust excluder lips is provided with above end, keep off oily lip and main lip to be connected with described bearing inner race respectively formation first sealing position and the second sealing position, described skeleton is provided with upper hem and lower hem, the length of described waist is 1.2-1.4mm, the utility model adds the length of waist, the shoe cream room between gear oil lip and main lip is made to increase the contact force reducing sealing position, reduce operating temperature, extend seal ring working life, and increase flanging on skeleton both sides, improve the support strength of skeleton, can effectively pre-drop-preventing cover.
Description
Technical field
The utility model relates to seal ring technical field, is specifically related to a kind of automobile belt wheel bearing seal ring.
Background technique
Automobile belt wheel bearing is the vitals of automobile driving system.The power system of automobile is coordinated to complete the operation such as starting, acceleration, deceleration of automobile.Automobile belt wheel bearing operating mode is quite severe, often be in high temperature, run up down, also be in high dust atmosphere simultaneously, and by axially, to impact and the radial centrifugal force of High Rotation Speed, torsional moment affect, so the requirement of automobile belt wheel bearing is very strict, if bearing damage, undesirable, probably cause the generation of accident, threat to life.The structural design existing defects of traditional a kind of automobile belt wheel bearing seal ring, sealing cannot ensure, grease can occur and to leak outside phenomenon, and seal ring support strength is inadequate, and long-term operate at high voltage easily deforms.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, a kind of automobile belt wheel bearing seal ring of good sealing effect, long service life.
For achieving the above object, the technological scheme that the utility model is taked is:
A kind of automobile belt wheel bearing seal ring, comprise body, end, the waist, the bearing inner race that are located at intrinsic skeleton, connect body and end, it is characterized in that described body is provided with near waist end the gear oil lip tilted to body, the main lip tilted to body is provided with below described end, dust excluder lips is provided with above end, keep off oily lip and main lip to be connected with described bearing inner race respectively formation first sealing position and the second sealing position, described skeleton is provided with upper hem and lower hem, and the length of described waist is 1.2-1.4mm.
As preferably, the described body the other end arranges outer lip.
As preferably, described outer lip is connected with body integral type with half round surface by inclined-plane.
As preferably, described skeleton is made up of rigid material.
As preferably, described body, end and waist are that integral type is connected.
As preferably, between described gear oil lip and main lip, form shoe cream room.
Compared with prior art, the utility model has the advantage of:
1, inside and outside skeleton, both sides add flanging, improve the support strength of skeleton, can effectively pre-drop-preventing cover.
2, the length of waist adds 0.4mm, and this shoe cream room just making to keep off between oily lip and main lip increases, and reduces the contact force of sealing position, reduces operating temperature, extends seal ring working life.
3, increase dust excluder lips above end, effectively pre-dust protection enters.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, body 1, end 2, outer lip 3, skeleton 4, waist 5, bearing inner race 6, keep off oily lip 11, first sealing position 12, main lip 21, dust excluder lips 22, second sealing position 23, inclined-plane 31, half round surface 32, upper hem 41, lower hem 42.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described further.
As shown in the figure, a kind of automobile belt wheel bearing seal ring, comprise body 1, end 2, be located at the skeleton 4 in body 1, connect the waist 5 of body 1 and end 2, bearing inner race 6, it is characterized in that: described body 1 is provided with the gear oil lip 11 tilted to body 1 near waist 5 end, the main lip 21 tilted to body 1 is provided with below described end 2, dust excluder lips 22 is provided with above end 2, keep off oily lip 11 and main lip 21 to be connected with described bearing inner race 6 respectively formation first sealing position 12 and the second sealing position 23, described skeleton 4 is provided with upper hem 41 and lower hem 42, the length of described waist 5 is 1.2-1.4mm, described body 1 the other end arranges outer lip 3, described outer lip 3 is connected with body 1 integral type with half round surface 32 by inclined-plane 31, described skeleton 4 is made up of rigid material, described body 1, end 2 with waist 5 for integral type is connected, shoe cream room is formed between described gear oil lip 11 and main lip 21.
A kind of automobile belt wheel bearing seal ring described in the utility model, compensate for the deficiencies in the prior art, inside and outside skeleton, both sides add flanging, improve the support strength of skeleton, can effectively pre-drop-preventing cover, the length of waist adds 0.4mm, and this just makes the shoe cream room kept off between oily lip and main lip increase, and reduces the contact force of sealing position, reduce operating temperature, extend seal ring working life, increase dust excluder lips above end, effectively pre-dust protection enters.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although what this paper was more employs body 1, end 2, outer lip 3, skeleton 4, waist 5, bearing inner race 6, keeps off oily lip 11, first sealing position 12, main lip 21, dust excluder lips 22, second sealing position 23, inclined-plane 31, half round surface 32, upper hem 41, lower hem 42 term, but do not get rid of the possibility using other term, use these terms to be only used to describe and explain essence of the present utility model more easily, the restriction that they are construed to any one additional is all contrary with the utility model spirit.
