Description

A kind of housing structure
Technical field
The utility model relates to a kind of housing structure.
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 housing structure of stability.
The purpose of this utility model is achieved through the following technical solutions:
A kind of housing structure, 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, and the bottom of described body is provided with the oil groove be communicated with described plunger hole, and 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, and the bottom of described body is provided with counterbore.
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 housing structure 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, and the bottom of described body is provided with the oil groove be communicated with described plunger hole, and 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, and the bottom of described body is provided with counterbore.The housing structure of this structure, its working life is higher and stability is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of housing structure described in the utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
According to drawings and embodiments the utility model is described in further detail below.
As shown in Figures 1 and 2, a kind of housing structure described in the utility model embodiment, comprise columniform body 1, the top of body 1 is equipped with plunger hole 2, and be provided with boss 3 in the middle of the top of body 1, the centre of body 1 is provided with the transmission shaft mounting hole 4 of through body 1, the bottom of body 1 is provided with the oil groove 5 be communicated with plunger hole 2, the top of body 1 is provided with the through hole 6 of inclination near the root place uniform ring of boss 3, and through hole 6 is communicated with transmission shaft mounting hole 4, and the bottom of body 1 is provided with counterbore 7.
Angle between the medial axis of through hole 6 and the medial axis of transmission shaft mounting hole 4 is 7 ~ 8 degree.More specifically, the angle in the present embodiment between the medial axis of through hole 6 and the medial axis of transmission shaft mounting hole 4 is 7.5 degree.The periphery of body 1 is provided with inclination angle 8 near top end.Oil groove 5 is coaxial with the medial axis of transmission shaft mounting hole 4.
The foregoing is only and mode of execution of the present utility model is described; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
