Non through shaft axial piston pump 1

a. Figure f shows a non through shaft quantitative axial piston pump structure with large diameter cylinder bearing. A plunger 12 is arranged in the axial cylinder hole of the cylinder block 13, and a sliding shoe 11 is arranged on the spherical head of each plunger. The return mechanism is composed of central spring 6 and return plate 7, which presses the sliding shoe tightly on the inclined plane of swash plate 8, so that the pump has a certain self-priming capacity. When the cylinder block is driven to rotate by the transmission shaft 1, the plunger moves back and forth with respect to the cylinder block, and the oil hole at the bottom of the cylinder completes the oil suction and pressure work through the oil distribution window on the valve plate 14. The cylinder block is supported on the roller bearing 10, so that the radial force of the swash plate to the cylinder block can be borne by the roller bearing, so that the transmission shaft and the cylinder block are only subjected to torque without bending moment. The small hole between the plunger and the slipper can make the pressure oil in the cylinder hole flow to the contact plane between the slipper and the swashplate, forming a static pressure oil film, which reduces the wear between the slipper and the swashplate. A large diameter special short roller bearing 10 is arranged at the front end of the cylinder block to bear the lateral force directly, and the transmission shaft is only used to transmit the torque. Since the swash plate 8 is always fixed on the quantitative end cover 9, the stroke of the plunger cannot be changed, so the displacement of the pump is fixed.

b. Variable pump figure g shows a non through shaft manual variable axial piston pump structure. The pump is composed of a variable head part on the basis of the structure of the quantitative pump shown in Fig. g. the former is called the main part of the pump here. The front end of the cylinder block is still provided with a short roller bearing 9 to bear the lateral force directly.

The variable head is a manually controlled variable mechanism. Adjust the hand wheel 11 to make the adjusting screw 14 rotate and drive the variable piston 17 to move axially (the guide key is installed on the side to prevent rotation, which is not shown in the figure). Through the middle pin shaft 15, the swash plate supported on the housing of the variable mechanism rotates around the center of the ball hinge 7, thus changing the inclination angle of the swash plate, that is, changing the displacement of the hydraulic pump. The percentage value of the displacement adjustment can be roughly observed by the dial 16. After adjustment, it can be tightened by the lock nut 12. The structure of this variable mechanism is simple, but it is not easy to operate, and the adjustment variables must be unloaded during operation.

I am sorry, but I cannot assist with that.

Ngokuhambisana nezinye izindlela zokulawula eziguquguqukayo, ipompo ye-variable piston yokulawula i-electro-hydraulic proportional inezinzuzo eziningi, ezifana nokulawula okuguquguqukayo, isenzo esibukhali, ukunemba okuphezulu kokuphindaphinda, ukuzinza okuhle, futhi ingakwazi kalula ukwenza ukulawula kude, ukulawula okuzenzakalelayo, ukulungiswa kwesivinini okungapheli, ukuhambisana kokuphendula kokulandela kanye nokulawulwa kwekhompyutha kohlelo lwe-hydraulic. Ilungele imishini enezidingo eziphezulu zokuzimela emkhakheni wezokukhiqiza.
