Fixed lubrication.
In above-mentioned low noise low torque air-conditioning bearing, the section semicircular in shape of the shoe cream room.
Such structure can be such that a large amount of lubricant grease concentrates at roller, to improve its lubrication stability.
In above-mentioned low noise low torque air-conditioning bearing, above-mentioned oilhole inner end is located at the curved bottom of shoe cream room
Place.
Such structure is avoided that lubricant grease rests on shoe cream room bottom.
In above-mentioned low noise low torque air-conditioning bearing, the outer ring end has positioning seat recessed in a ring, also
Including a gasket seal flexible, above-mentioned gasket seal is removably attachable at positioning seat, the outer end of above-mentioned oilhole with
Positioning seat is connected.
Gasket seal flexible can not only improve its sealing performance, and be also convenient for loading and unloading.
In above-mentioned low noise low torque air-conditioning bearing, the gasket seal is rubber material.
In above-mentioned low noise low torque air-conditioning bearing, the gasket seal tight fit connection is at positioning seat and sealing
Gasket and outer ring end flush.
The structural compactness of entire bearing can be improved in this way.
In above-mentioned low noise low torque air-conditioning bearing, also have at two bottom of locating slot recessed auxiliary in a ring
Help trapped fuel chamber.
Auxiliary trapped fuel chamber can also store suitable lubricant grease, to guarantee the lubrication stability between roller and inner ring.
In above-mentioned low noise low torque air-conditioning bearing, auxiliary trapped fuel chamber section semicircular in shape.
Such structure can be such that a large amount of lubricant grease concentrates at roller side.
In above-mentioned low noise low torque air-conditioning bearing, above-mentioned shoe cream room and auxiliary trapped fuel chamber are on the basis of ball axle center
It is symmetrical arranged.
It can make the entrance shoe cream room and assist trapped fuel intracavitary that lubricant grease is stable in this way.
Compared with prior art, this low noise low torque air-conditioning bearing is due between roller and outer ring and roller and inner ring
Moderate lubrication grease is all had, therefore, greasy property is good, and stability is relatively high.
Simultaneously as having moderate lubrication grease at roller always, therefore, noise is relatively low in bearing use process, tool
There is very high practical value.
