Description
Technical Field
The utility model relates to a bearing processing technology field, in particular to high leakproofness roller bearing of damping.
Background
The bearing is a component for fixing and reducing the load friction coefficient in the mechanical transmission process. It can also be said that the member for reducing the friction coefficient during power transmission and keeping the center position of the shaft fixed when the other members are moved relative to each other on the shaft. The bearing is a lightweight part in modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load of equipment in the transmission process. The bearings can be classified into rolling bearings and sliding bearings according to the frictional properties of the moving elements. The roller bearing in the prior art has no damping function, when the roller bearing rotates under the action of a large load due to the gap of the bearing in the mechanical operation, vibration is generated, gaps are generated between the rolling bodies and the inner ring and between the rolling bodies and the outer ring, the normal operation of machinery is affected, good dustproof performance is not provided, and dust easily enters the roller bearing to cause mechanical failure.
The utility model provides a damping high leakproofness roller bearing solves above-mentioned technical problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome prior art's cross roller bearing when the rotation of axle under great alternating load effect, can produce the vibration, cause the rolling element to produce the clearance with interior outer lane, influence the technical problem of the normal function of machinery, provide a high leakproofness roller bearing of damping in order to solve above-mentioned problem.
For realizing the purpose of the utility model, the utility model adopts the technical scheme that: a roller bearing with vibration damping and high sealing performance is characterized in that: including shaft hole, outer lane, inner circle, rubber outer lane, ball groove, ball keep ware and sealing washer, the inner circle is fixed inside the outer lane, the rubber outer lane is fixed outside the outer lane, the ball groove is located between outer lane and the inner circle, the ball is installed in the ball groove, the ball keeps the ware to link together through the ball, the inside both ends in ball groove are installed to the sealing washer, be equipped with the profile of tooth arch on the outside of outer lane, the rubber outer lane inboard is equipped with the profile of tooth recess, the profile of tooth is protruding to be in the same place with profile of tooth recess phase-match, the outer lane passes through the profile of tooth arch with the rubber outer lane and links together with profile of tooth recess grafting each other, the protruding.
Furthermore, the hardness of the outer ring and the inner ring is HB 225-275.
Compared with the prior art, the utility model has the advantages that: the rubber outer ring is arranged outside the outer ring, the outer ring and the rubber outer ring are connected with each other, a buffer groove is formed in the position of the outer ring and the rubber outer ring, when the machine vibrates, the bearing can effectively buffer and damp vibration, the influence of vibration on the bearing is reduced, gaps are generated between the rolling body and the inner ring and the outer ring, the running precision of the bearing is guaranteed, the rubber outer ring and the sealing ring play a role in sealing the bearing, dust can be effectively prevented from entering the bearing, and the running precision and the service life of the bearing are further guaranteed.
