Description
Technical field
The present invention relates to a kind of pluger type hydraulic pump, especially a kind of inclined shaft pump of gear drivig cylinder motion.
Background technology
Several frequently seen hydraulic pump, such as gear pump, vane pump, screw pump and plunger pump.Gear pump is adapted to high-pressure low-flow
Occasion, but flow pulsation is larger, and variable can not be realized, discharge capacity is non-adjustable, is a kind of constant displacement pump；Vane pump is to working speed
Restricted and specific contact pressure is big, sensitive to fluid Nature comparison；Screw pump quality is small, small volume, allows to use high rotating speed, tool
There is higher volumetric efficiency, but it is substantially a kind of external toothing formula cycloid gear pump, and tooth form is complicated, processing difficulties, is a kind of
Constant displacement pump；Plunger pump is easy to process, and fit precision is high, it is easy to accomplish variable, while it is applied to low discharge occasion, quality and volume
It is relatively small.
Pluger type hydraulic pump is divided into inclined disc type and two kinds of structures of clino-axis type again, can be with the characteristics of two kinds of structures of Comprehensive Correlation
Know, bent axis type axial piston pump can reduce piston shoes swash plate this friction pair by contrast, and this is to low-viscosity media lubrication circumstances
Favourable.Bent axis type axial piston pump can realize bigger inclination angle, and then cause cylinder body and diameter of plunger needed for same displacement parameter
It is smaller, volume is reduced, reduces quality.The most common type of drive of bent axis type axial piston pump is to stir cylinder body by plunger connecting rod to rotate,
Plunger connecting rod needs to bear larger bending moment of torsion.In order to improve plunger stress, using center hinge type of drive, but center hinge
Very big moment of torsion will be born, being limited to its structure can not be too big, so center hinge will bear larger twisting resistance, meanwhile, it is this
The structure of pump is more complicated, introduces new kinematic pair, reduces the reliability of whole pump.Each side factor is considered, using gear
The mode of drivig cylinder motion is the most reasonable.But the inclined shaft pump size of existing gear drivig cylinder motion mode is larger, makes
It is not high with the life-span.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, there is provided a kind of inclined shaft of gear drivig cylinder motion
Pump.
The technical solution adopted for the present invention to solve the technical problems is：A kind of inclined shaft pump of gear drivig cylinder motion,
The inclined shaft pump, which has, is bolted the fixed preceding pump housing and the rear pump housing,
Main shaft disk is installed in the front pump body, sleeve, barrel forward end and main shaft are arranged with the main shaft of the main shaft disk
Between be provided with deep-groove ball ceramic bearing, be provided with ceramic bearing between sleeve rear end and main shaft, sleeve rear end and the preceding pump housing it
Between be provided with plain thrust bearing, the front end of the preceding pump housing is provided with drive end bearing bracket；
Cylinder body is provided with the pump housing after described, mandrel is installed in the cylinder body, is circumferentially offered on cylinder body some flat
In being provided with plunger and plunger pair in the plunger hole of mandrel, plunger hole, plunger is connected with connecting rod, connected on the front end face of cylinder body row
There is the bevel gear being engaged with main shaft back-end disk epicone gear, valve plate, valve plate and cylinder body are provided with the rear end face of cylinder body
Between be provided with floating liner plate, the rear end of valve plate is provided with rear end cap.
The beneficial effects of the invention are as follows：Inclined shaft pump of the present invention uses combination bearing, reduces the size of pump, improves use
In the life-span, there is certain pollution-resistant.
