Description
Technical field：
The utility model is related to hydraulic pump to manufacture field, more particularly to a kind of hydraulic pump split axle sleeve.
Background technology：
Hydraulic pump provides a kind of Hydraulic Elements of fluid under pressure for hydraulic drive, is one kind of pump.Its function is dynamic
The mechanical energy of power machine (such as motor and internal combustion engine) is converted into the pressure energy of liquid.Influence the service life factor of hydraulic pump very
It is many, except pump itself design, manufacture factor are outer and some used with pump related elements (such as shaft coupling, oil filter) selection,
Operation during trial run and run etc. also has relation.
There is certain defect in the axle sleeve of hydraulic pump, off-load ability is weak, oil return ability, rubbing surface sealing property after installing
The shortcomings of difference, after causing axle sleeve to assemble, the performance of pump is had a strong impact on, shorten the service life of pump.
Utility model content：
In order to make up prior art problem, the purpose of this utility model is to provide a kind of hydraulic pump split axle sleeve, structure
Reasonable in design, it is possible to increase the off-load ability of pump, oil return performance, the sealing property of rubbing surface extends the service life of pump.
The technical solution of the utility model is as follows
Hydraulic pump split axle sleeve, including cylinder, it is characterised in that sliding bearing, cylinder ring are installed in the cylinder
Docking platform is cut with wall, compensating groove, compensating groove lower end and docking platform face are symmetrically arranged with described cylinder left side
Concordantly, one of compensating groove top is provided with oil-recovery tank, and oil-recovery tank is obliquely installed and upper end and cylinder bore UNICOM, and lower end extends
To cylinder edge and with compensating groove UNICOM；
Described cylinder right side is provided with the sealing ring mounting groove coaxial with cylinder bore, and sealing ring mounting groove is c-type,
Sealing ring mounting groove upper end open is to cylinder edge, lower ending opening to docking platform lower surface.
Described hydraulic pump split axle sleeve, it is characterised in that described compensating groove is the gap slot of wedge shape, and compensating groove is certainly
Cylinder bore is opened up with docking platform end face midpoint to docking platform end, and off-load groove depth is from platform end to cylinder
Endoporus gradually becomes shallower as with docking platform end face midpoint.
Described hydraulic pump split axle sleeve, it is characterised in that described sealing ring mounting groove upper end open is located at cylinder
The left upper of right side.
Described hydraulic pump split axle sleeve, it is characterised in that described sliding bearing is fit into from cylinder left side
Endoporus, sliding bearing left side is concordant with cylinder left side, and the positioning step of endoporus, sliding bearing are withstood in sliding bearing right side
Right side is concordant with oil-recovery tank bottom land.
The utility model has the advantages that：
The utility model reasonable in design, it is possible to increase the off-load ability of pump, oil return performance, the sealing of rubbing surface
Can, extend the service life of pump.
Brief description of the drawings：
Fig. 1 is sectional view of the present utility model.
Fig. 2 is left view of the present utility model.
Fig. 3 is right view of the present utility model.
Specific embodiment：
Referring to accompanying drawing：
Sliding bearing 2 is installed in hydraulic pump split axle sleeve, including cylinder 1, cylinder 1, it is right to be cut with the ring wall of cylinder 1
Platform 3 is connect, compensating groove 4 is symmetrically arranged with the left side of cylinder 1, the lower end of compensating groove 4 is concordant with the face of docking platform 3, one of them
Compensating groove top is provided with oil-recovery tank 5, and oil-recovery tank 5 is obliquely installed and upper end and the endoporus UNICOM of cylinder 1, and lower end extends to the side of cylinder 1
Edge and with the UNICOM of compensating groove 4；
The right side of cylinder 1 is provided with the sealing ring mounting groove 6 coaxial with cylinder bore, and sealing ring mounting groove 6 is c-type, close
The upper end open of seal mounting groove 6 is to the edge of cylinder 1, lower ending opening to the lower surface of docking platform 3；
Compensating groove 4 is the gap slot of wedge shape, and compensating groove 4 is from cylinder bore and docking platform end face midpoint to docking platform
End opens up, and the depth of compensating groove 4 gradually becomes shallower as from platform end to cylinder bore with docking platform end face midpoint.
The upper end open of sealing ring mounting groove 6 is located at the left upper of the right side of cylinder 1.
Sliding bearing 2 is fit into endoporus from the left side of cylinder 1, and the left side of sliding bearing 2 is concordant with cylinder left side, sliding
The positioning step 7 of endoporus is withstood in the right side of dynamic bearing 2, and sliding bearing right side is concordant with the bottom land of oil-recovery tank 5.
The utility model is located in gear pump case, between front and rear cover, is used in pairs, plays support driving gear and quilt
The effect of moving gear；Meanwhile, also act as the parting seal effect to two oil pockets of hydraulic oil and low pressure oil；Ensure height pumping cavity
Hydraulic oil it is completely separable, it is impossible to string oil.
