Description
Technical field
The utility model relates to a kind of cylinder body.
Background technique
Axial variable plunger pump is an important device of hydraulic system, it relies on plunger to-and-fro motion in cylinder body, the vibration-direction of plunger is parallel with the central shaft of cylinder body, thus make plunger to-and-fro motion in plunger hole produce volume-variation to realize force feed, oil suction, the advantage such as have that rated pressure is high, compact structure, efficiency are high due to plunger pump and Flow-rate adjustment is convenient, is therefore widely used in hydraulic press, engineering machinery and boats and ships.
Cylinder body is driven to rotate when axial variable plunger pump works by transmission shaft, make to be slidedly assemblied in cylinder body plunger hole inner plunger synchronous rotary, variable piston passes through to drive the Angulation changes of variable head and backhaul swash plate thus the adjustment realizing plunger reciprocates stroke, realize the change of oil suction and fuel delivery, oil distribution casing is installed in the bottom of cylinder body simultaneously, and oil distribution casing is used for the oil duct conversion of plunger turnover oil.Due to the kernel component that cylinder body is plunger pump, therefore working life of cylinder body and stability are directly connected to the quality of plunger pump.
Model utility content
The purpose of this utility model is the problem overcoming above-mentioned prior art, provides a kind of working life higher and the good a kind of cylinder body of stability.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cylinder body, comprise columniform body, the top of described body is equipped with plunger hole, boss is provided with in the middle of the top of described body, the centre of described body is provided with the transmission shaft mounting hole of through described body, the bottom of described body is provided with the oil groove be communicated with described plunger hole, the top of described body is provided with the through hole of inclination near the root place uniform ring of described boss, described through hole is communicated with described transmission shaft mounting hole, the bottom of described body is provided with counterbore, and the periphery of described body is provided with the radial through pore to described plunger hole.
Further, the angle between the medial axis of described through hole and the medial axis of described transmission shaft mounting hole is 7 ~ 8 degree.
Further, the angle between the medial axis of described through hole and the medial axis of described transmission shaft mounting hole is 7.5 degree.
Further, the periphery of described body is provided with inclination angle near top end.
Further, described oil groove is coaxial with the medial axis of described transmission shaft mounting hole.
A kind of cylinder body described in the utility model, comprise columniform body, the top of described body is equipped with plunger hole, boss is provided with in the middle of the top of described body, the centre of described body is provided with the transmission shaft mounting hole of through described body, the bottom of described body is provided with the oil groove be communicated with described plunger hole, the top of described body is provided with the through hole of inclination near the root place uniform ring of described boss, described through hole is communicated with described transmission shaft mounting hole, the bottom of described body is provided with counterbore, the periphery of described body is provided with the radial through pore to described plunger hole.The cylinder body of this structure, its working life is higher and stability is better.
