Abstract
The utility model discloses a separate preloaded axial plunger pump comprising a pump body, a pump case, a cylinder, a ramming piston, a slip boot, a drive axle, a port plate and a variable head. The preloaded device of the slip boot and the variable head and the preloaded device of the port plate are two separately installed preloaded devices. The utility model has a simple structure and reliable operation.
Description
Technical field:
The utility model relates to a kind of plunger pump.
Background technique:
Existing axial piston pump, the pre-tightening apparatus of piston shoes and variable head and the pre-tightening apparatus of cylinder body and thrust plate are same pre-tightening apparatus, and structure is not compact, and pretightening force is unreasonable, and functional reliability is undesirable.On other structural types, also there is more unreasonable part.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the independent pretension axial piston pump of reliable operation.
Technical solution of the present utility model is:
A kind of independent pretension axial piston pump, comprise the pump housing, pump case, cylinder body, plunger, piston shoes, transmission shaft, thrust plate, variable head, it is characterized in that: the pre-tightening apparatus of piston shoes and variable head and the pre-tightening apparatus of cylinder body and thrust plate are two independent pre-tightening apparatus that are provided with.
The pre-tightening apparatus of piston shoes and variable head is the butterfly spring locking device.The pre-tightening apparatus of cylinder body and thrust plate is the butterfly spring locking device.The pre-tightening apparatus of piston shoes and variable head comprises the bearing pin that is contained on the variable head, and dress is pressed in the gland on the backhaul dish on the bearing pin, and the backhaul dish is pressed on the piston shoes, dress butterfly spring hold-down mechanism on the gland.The pre-tightening apparatus of cylinder body and thrust plate comprises the bearing pin that is contained on the transmission shaft, suit butterfly spring hold-down mechanism on the bearing pin.Piston shoes comprise the base steel material bodies, are combined with the alloyed copper material layer on the rubbing surface of base steel material bodies.Cylinder body and cylinder sleeve are incorporate form.Be provided with regulating clam in the pump housing runner, be the double flow channel form.Adopt involute splines to be connected between transmission shaft and the cylinder body.Cylinder body block bearing between cylinder body and the pump case adopts needle bearing.
The utility model is rational in infrastructure, and the pre-tightening apparatus of piston shoes and variable head and the pre-tightening apparatus of cylinder body and thrust plate are two independent pre-tightening apparatus that are provided with, and make pretightening force separately more reasonable, and it is more reliable to work; The pre-tightening apparatus of cylinder body and thrust plate adopts the butterfly spring locking device, makes structure compact more, more effectively prevents toppling and alternating stress that the cylinder body power of toppling causes the cylinder body block bearing to be subjected to of cylinder body, thereby the mechanicalness noise of bearing is descended.The pre-tightening apparatus of piston shoes and variable head adopts the butterfly spring locking device, can make pretightening force more reasonable, throw off when more effectively preventing work, suction capacity is improved, and oil pump is sucked under the situation of air, it is good that piston shoes and variable head are fitted, and prevents to pull plunger piston slippery boots, thereby make the oil pump safety and reliability.Adopt the integrated design of cylinder body, cylinder sleeve, intensity is improved greatly, make the cylinder hole not produce interference stress again, make the motion in plunger case hole more reliable.Be provided with regulating clam in the pump housing runner, be the double flow channel form, dispensing window intensity is improved, prevent distortion, after the shunting, oil stream is more reasonable on the other hand, reduces the hydraulic pressure noise.Adopt involute splines to be connected between transmission shaft and the cylinder body, compare traditional rectangular spline, the involute splines transmission is steady more, intensity is high.Cylinder body block bearing between cylinder body and the pump case adopts needle bearing, has both reduced overall volume, makes mechanicalness noise that more decline is arranged again.Piston shoes adopt the form that is combined with the alloyed copper material layer on the rubbing surface of base steel material bodies, have both improved the pull-off strength of plunger piston slippery boots ball strand, guarantee that again the planar friction pair is more reasonable.
