Background technology
Currently, domestic automobile clutch bearing, the general nitrile rubber sealing ring for making skeleton using Fine Steel Casting iron plate, this
Kind structure can meet the performance requirement of automobile clutch bearing under general industrial and mining condition.
As auto industry develops to passenger car, the engineering truck of large torque heavy duty, to the property of clutch and its bearing products
Requirements at the higher level, the large torque heavy duty passenger car of particular/special requirement, -20 DEG C of the temperature in use of engineering truck clutch bearing can be also proposed
~ 200 DEG C, reach 220 DEG C under limiting case, it is desirable that there is waterproof, sediment prevention, leakproof fat.With this condition, original steel plate bone
Frame nitrile rubber sealing structure has been completely unsuitable for, therefore the present invention develops new large torque heavy duty high temperature resistant, waterproof, sediment prevention, prevents
Leak the pull type clutch bearing seal structure of fat.With torque in 1800 ~ 2000N.M, temperature under the conditions of -20 DEG C ~ 200 DEG C just
The performance often to work.
Invention content
A kind of novel high torque heavy duty clutch bearing waterproof of present invention exploitation, sediment prevention, leakproof fat, refractory seals knot
Structure.The performance worked normally under the conditions of -20 DEG C ~ 200 DEG C in 1800 ~ 2000N.M, temperature with torque.Including novel axis
Structure, the corresponding fit structure of sealing ring and heat-resisting material on bearing outer-ring for sealing.
The technical solution of invention is：A kind of large torque heavy duty clutch separation axle sealing structure, including it is sealing ring, close
Seal baffle ring and bearing outer ring installation position corresponding with bearing inner race, it is characterised in that：The bearing outer ring is corresponding
Installation position is in the outer ring at both ends through L cylinder groove faces；The corresponding installation position of the bearing inner race is outside the inner ring at both ends
Diameter L cylinder groove faces；The sealing ring is equipped with stainless steel plate skeleton, outer seal lip and interior sealing lip, stainless steel plate skeleton outer end
Equipped with one section of cylindrical surface L, which fixes in the outer ring at bearing outer ring both ends through L cylinder groove faces interference fit, installation；
Through being equipped with one section of cylindrical surface L and rubber adhesive layer, the inner ring outer diameter on this section of cylindrical surfaces L and bearing inner race both ends outside backup ring
L cylinder groove faces interference fit, installation are fixed；Profit is equipped between sealing ring and its outer seal lip, interior sealing lip and backup ring
Consistent lubricant.
Outer ring endoporus L cylinder groove faces described in technical solution of the invention are that the L of H5 class precision grindings justifies
Cylinder ensures the reliability and precision of cooperation installation.
Outer ring endoporus L cylinder groove faces described in technical solution of the invention are the above grinding of medium accuracy
The cylindrical surfaces L.
Sealing ring described in technical solution of the invention includes stainless steel plate skeleton and its fluorine system rubber on surface
The outer seal lip of adhesive layer and outer middle side part, bottom interior sealing lip, stainless steel plate skeleton use punching press stainless steel plate.
Backup ring described in technical solution of the invention is by the stainless steel plate skeleton equipped with one section of cylindrical surface L
And its fluorine system rubber adhesive layer on surface is constituted, stainless steel plate skeleton uses punching press stainless steel plate.
The present invention has the following effects that：
Coordinate for L cylindrical interferences in the stainless steel plate skeleton installation position of sealing ring through L cylinders groove face in outer ring, is passed through outside inner ring
L coordinates in the stainless steel plate skeleton installation position of backup ring for L cylindrical interferences through cylinder groove face, ensure that reliable peace
Fill intensity, it is often more important that the stainless steel plate skeleton of sealing ring installation position has identical heat with bearing outer ring in the case of a high temperature
Expansion character makes sealing ring ensure reliable matching relationship and intensity with bearing outer ring always, avoids original sealing ring mounting portion
Position to lead to since the thermal expansion with bearing outer ring material is inconsistent to occur loosenings when rubber, gap, lubricating grease are revealed.
The present invention has the characteristics that the normal working performance under -20 DEG C ~ 200 DEG C hot conditions.Present invention is mainly used for big
Torque heavy duty passenger car, the pull type clutch bearing waterproof at engineering truck clutch position, sediment prevention, high temperature resistant sealing structure.
