Description
Technical field
The utility model relates to field of aerospace technology, particularly a kind of long lifetime gear Sliding bearing for pump with spring-compensating.
Background technique
Sliding bearing is the bearing worked under sliding friction, sliding bearing stable working, reliable, noiseless, under liquid lubrication condition, the undeveloped life of the lubricated oil content of slidingsurface directly contacts, can also greatly reduce frictional loss and surface abrasion, sliding bearing can be applied in long lifetime gear pump.
Due to the sliding friction between gear and sliding bearing, thus add the leakage of gear pump gear end face, reduce gear pump mechanical efficiency; In addition, during high gear pump work, oil-feed efficiency is lower, also there will be Oil-blocking Phenomenon in Gear Oil Pump, thus causes noise of gear pump and decrease gear life.
Model utility content
The technical problems to be solved in the utility model visitor takes existing defect, a kind of long lifetime gear Sliding bearing for pump with spring-compensating is provided, can be applied in long lifetime gear pump, for gear rotary support is provided, pressure between gear face sealing compensation and off-load wheel tooth, effectively can solve the problem in background technique.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of long lifetime gear Sliding bearing for pump with spring-compensating of the utility model, the straight pin comprising sliding bearing body and be arranged on sliding bearing body junction plane and counterbalance spring, sliding bearing body front described in it is provided with entrance compensating groove and outlet compensating groove, described entrance compensating groove is provided with guiding gutter to bearing centre, be provided with pod apertures in described outlet compensating groove and lead to the sliding bearing body back side, the described sliding bearing body back side is provided with accentric support, and described accentric support is provided with O shape ring recess.
As a kind of optimal technical scheme of the present utility model, described sliding bearing body is symmetrical about center line.
As a kind of optimal technical scheme of the present utility model, outer avris non-uniform Distribution 10 the described counterbalance springs of described accentric support.
As a kind of optimal technical scheme of the present utility model, described sliding bearing body A face and described sliding bearing body B face are provided with molybdenum disulfide.
As a kind of optimal technical scheme of the present utility model, be provided with pod apertures in outlet compensating groove and lead to the symmetrical bearing back side, the gear pump outlet on gear pump body is communicated with the sliding bearing body back side by pod apertures.
The beneficial effect that the utility model reaches is:
The long lifetime gear Sliding bearing for pump of this band spring-compensating, comprise sliding bearing body, straight pin, counterbalance spring, entrance compensating groove, outlet compensating groove and accentric support, because sliding bearing body front is provided with entrance compensating groove and outlet compensating groove, gear pump inlet width can be increased, oil-feed efficiency during raising high gear pump work, eliminate the peculiar entrap phenomenon of gear pump, reduce noise of gear pump, improve gear life, reduce noise, because sliding bearing A face and B face are provided with molybdenum disulfide, the sliding friction in gear and sliding bearing A face and B face can be reduced, reduce gear pump gear face leakage, improve gear pump mechanical efficiency, because the sliding bearing body back side is provided with accentric support, can the radial stress that produces in movement process of active balance gear.
