Abstract
The said hydraulic pump includes casing, main shaft fixed at incllination angle to casing, pin and plunger. It features its plunger connected via cardan to main shaft, two symmetrical cylinders at the two ends of plunger and main shaft with through shaft structure. Owing to its double-acting structure, the plunger serves two working cavities simultaneously, so that working efficiency and thus the displacement are raised by one time. The present invention has the merits of high working pressure, large output flow, high efficiency, etc.
Description
The present invention relates to the power source oil hydraulic pump in a kind of Hydraulic Power Transmission System.
In the existing plunger pump technique, generally each plunger is an active chamber service, and efficient is low, and the axial force of main shaft is big, and complex structure expands.
The purpose of this invention is to provide a kind of plunger that universal joint connects that has, is the double-acting clino-axis type axial plunger pump of two cylinder body services simultaneously.
Purpose of the present invention can realize by following technical proposal;
The present invention includes shell.Become inclination angle fixing main shaft, pin and plunger with shell, it is characterized in that: described plunger is connected on the main shaft by universal joint.Respectively there is a cylinder body of symmetry mutually at the two ends of described plunger.Described main shaft is the shaft type structure.
The present invention compared with prior art has following advantage:
1. structure of the present invention has adopted double-acting form.Making each plunger is two active chamber services simultaneously.Its working efficiency is doubled, and correspondingly discharge capacity also doubles.
2. the present invention has the working pressure height, is suitable for the rotating speed height, and the pressure oil output flow is big, and pressure oil flow pulsation is little, and noise is low, and power-mass ratio reaches volumetric efficiency and the high advantage of mechanical efficiency greatly.
3. the present invention is simple in structure, and volume is little.
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cross section view of A-A of the present invention.
Wherein: 1. pin; 2. direction saves; 3. plunger; 4. shell; 5. cylinder body; 6. oil distribution casing; 7. bearing; 8. main shaft; 9. bearing support.
Embodiment: the present invention includes shell 4.With fixing main shaft 8, pin 1 and the plunger 3 in 4 one-tenth inclination angles of shell.Described plunger 3 is connected on the main shaft 8 by universal joint 2.Respectively there is a cylinder body 5 of symmetry mutually at the two ends of described plunger 3.The other end of cylinder body 5 is then respectively by two secondary oil distribution casings 6 are housed.Described main shaft 8 is the shaft type structure.Two countershaft bearings, 9, two countershaft bearings 9 were interior by two supplementary bearings 7 are housed before and after be equipped with at shell 4 two ends, and pin 1 is housed on the main shaft 3.When main shaft 8 rotations, by the plunger 3 that is connected in main shaft 8, pin 1 just forces plunger 3 to make axially back and forth fore and aft motion in the hole of cylinder body 5 with universal joint 2, constantly back and forth change the size of cylinder body 5 hole content cavity volumes, constantly reach oil suction and press oily purpose, thereby satisfy the basic demand of hydraulic pump works.
Claims (3)
1. double-acting clino-axis type axial plunger pump, comprise shell 4, with fixing main shaft 8, pin 1 and the plunger 3 in 4 one-tenth inclination angles of shell, it is characterized in that: described plunger 3 centers are connected on the main shaft 8 by universal joint 2.
2. a kind of double-acting clino-axis type axial plunger pump according to claim 1 is characterized in that: respectively there is a cylinder body 5 of symmetry mutually at the two ends of described plunger 3.
3. the described a kind of double-acting clino-axis type axial plunger pump of root a tree name claim 1 is characterized in that: described main shaft 8 is the shaft type structure.
