Friction loss and surface abrasion, sliding bearing can be applied in long-life gear pump.
Due to the sliding friction between gear and sliding bearing, so as to increased the leakage of gear pump gear end face, drop
Low gear pump mechanical efficiency；In addition, oil-feed is less efficient during high gear pump work, gear pump is there is also
Pocketed oil phenomenon, so as to causing noise of gear pump and reducing gear life.
Content of the invention
The technical problem to be solved in the present invention visitor is to take existing defect, provides a kind of long-life with spring-compensating
Gear Sliding bearing for pump, can apply in long-life gear pump, be that gear provides rotation support, gear end
Face sealing compensation and off-load gear between cog pressure, can be with the problem in effectively solving background technology.
In order to solve above-mentioned technical problem, the invention provides following technical scheme：
A kind of long-life gear Sliding bearing for pump with spring-compensating of the present invention, including sliding bearing body and peace
The straight pin being mounted on sliding bearing body faying face and counterbalance spring, its described sliding bearing body front set
Have entrance compensating groove and outlet compensating groove, the entrance compensating groove is provided with guiding gutter to bearing centre, described go out
Pod apertures are provided with mouth compensating groove and lead to the sliding bearing body back side, the sliding bearing body back side is provided with bias
Support, the accentric support is provided with O-ring groove.
Used as a preferred technical solution of the present invention, the sliding bearing body is symmetrical with regard to center line.
As a preferred technical solution of the present invention, outer 10 institutes of avris non-uniform Distribution of the accentric support
State counterbalance spring.
As a preferred technical solution of the present invention, the sliding bearing body A face and the sliding bearing sheet
Body B face is provided with molybdenum bisuphide.
As a preferred technical solution of the present invention, pod apertures are provided with outlet compensating groove and lead to the symmetrical bearing back of the body
Face, the gear pump outlet on gear pump body connect the sliding bearing body back side by pod apertures.
The beneficial effect reached by the present invention is：
The long-life gear Sliding bearing for pump with spring-compensating, including sliding bearing body, straight pin, benefit
Spring, entrance compensating groove, outlet compensating groove and accentric support is repaid, as sliding bearing body front is provided with entrance
Compensating groove and outlet compensating groove, by increasing capacitance it is possible to increase gear pump inlet width, oil-feed effect when improving high gear pump work
Rate, eliminates the peculiar pocketed oil phenomenon of gear pump, reduces noise of gear pump, improve gear life, reduce noise, by
Molybdenum bisuphide is provided with sliding bearing A face and B face, gear can be reduced with sliding bearing A face and the cunning in B face
Dynamic friction, reduces gear pump gear face leakage, improves gear pump mechanical efficiency, as sliding bearing body is carried on the back
Face is provided with accentric support, being capable of the radial stress that produces in motion process of active balance gear.
