Description
Technical field
The utility model relates to Manufacturing Technology for Automotive Parts field, is specifically related to a kind of high leak tightness automobile clutch bearing sealed ring.
Background technique
Clutch release bearing unit is the vitals of automobile clutch system.By the clutch moving axially enforcement clutch of release bearing, thus cut off or connect the power contact between reasonable match system, complete the operations such as the starting of automobile, stopping, gear shift.So very strict for the requirement of release bearing unit, if bearing damage, undesirable, probably cause the clutch work of automobile malfunctioning.Clutch release bearing unit operating mode is quite severe, and be often in high temperature, mean temperature 120 DEG C, without cool condition.Also be in high dust atmosphere, because friction disc wear produces more dust, when being separated, bearing runs up in addition simultaneously, and by axially, to impact and the radial centrifugal force of High Rotation Speed, torsional moment affect.The structural design existing defects of traditional clutch release bearing seal ring, the sealing position design of its radial direction, larger impact can be produced on its sealing in the bump injury receiving notch, the oil storage space of seal ring lip is less, internal grease easily leaks outside, and external agency easily enters wherein, and seal ring waist width is inadequate, toughness is poor, easily damages.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the high leak tightness automobile clutch bearing sealed ring of long service life.
For achieving the above object, the technological scheme that the utility model is taked is:
A kind of high leak tightness automobile clutch bearing sealed 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, the secondary lip tilted to body is provided with above end, described gear oil lip is connected to be formed with described bearing inner race and keeps off oil seal position, described main lip and secondary lip are connected respectively at bearing inner race and form axial seal position and radial seal position, described skeleton is provided with upper hem and lower hem, the diameter of described waist is 1.0-1.2mm.
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, the diameter of waist adds 0.2mm, and both sides add flanging inside and outside skeleton, improves the support strength of skeleton, can effectively pre-drop-preventing cover.
2, add the angle of inclination keeping off oily lip, the shoe cream room volume making to keep off between oily lip and main lip increases, and effectively prevents grease from leaking outside, reduces the contact force of sealing position, reduce operating temperature, extends seal ring working life.
3, major-minor lip is connected with bearing inner race respectively and forms axial seal position and radial seal position, strengthens sealing, effectively prevents foreign matter from entering.
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, gear oil seal position 12, main lip 21, secondary lip 22, axial seal position 23, radial seal position 24, 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 high leak tightness automobile clutch bearing sealed 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 near waist 5 end the gear oil lip 11 tilted to body 1, the main lip 21 tilted to body 1 is provided with below described end 2, the secondary lip 22 tilted to body 1 is provided with above end 2, described gear oil lip 11 is connected to be formed with described bearing inner race 6 and keeps off oil seal position 12, described main lip 21 and secondary lip 22 are connected respectively at bearing inner race 6 and form axial seal position 23 and radial seal position 24, described skeleton 4 is provided with upper hem 41 and lower hem 42, the diameter of described waist 5 is 1.0-1.2mm, 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 high leak tightness automobile clutch bearing sealed ring described in the utility model, compensate for the deficiencies in the prior art, the diameter of waist adds 0.2mm, and both sides add flanging inside and outside skeleton, improve the support strength of skeleton, can effectively pre-drop-preventing cover, add the angle of inclination keeping off oily lip, the shoe cream room volume kept off between oily lip and main lip is increased, effectively prevent grease from leaking outside, reduce the contact force of sealing position, reduce operating temperature, extend seal ring working life, major-minor lip is connected with bearing inner race respectively and forms axial seal position and radial seal position, strengthen sealing, effectively prevent foreign matter from entering.
