Description
Technical field
The utility model is related to a kind of pluger type hydraulic pump, especially a kind of inclined shaft pump of gear drivig cylinder movement.
Background technology
Several frequently seen hydraulic pump, such as gear pump, vane pump, screw pump and plunger pump.Gear pump is suitble to high-pressure low-flow
Occasion, but flow pulsation is larger, and can not achieve variable, and 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, to fluid Nature comparison sensitivity；Screw pump quality is small, small, allows using high rotating speed, tool
There is higher volumetric efficiency, but it is substantially a kind of external toothing formula cycloid gear pump, 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 suitable for small flow occasion, quality and volume
It is relatively small.
The characteristics of pluger type hydraulic pump is divided into as inclined disc type and two kinds of structures of clino-axis type, two kinds of structures of Comprehensive Correlation, can be with
Know, bent axis type axial piston pump can reduce piston shoes swash plate this friction pair in contrast, this is to low-viscosity media lubrication circumstances
Advantageous.Bent axis type axial piston pump can realize the inclination angle of bigger, so that cylinder body and diameter of plunger needed for same displacement parameter
Smaller reduces volume, reduces quality.The most common type of drive of bent axis type axial piston pump is to stir cylinder body rotation by plunger connecting rod,
Plunger connecting rod needs to bear larger bending torque.In order to improve plunger stress, using center hinge type of drive, but center hinge
Very big torque will be born, being limited to its structure cannot 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.Various aspects factor is considered, using gear
The mode of drivig cylinder movement is the most reasonable.But the inclined shaft of existing gear drivig cylinder motion mode pump size is larger, makes
It is not high with the service life.
