Problems solved by technology

[0002] Whether the axial piston pump (motor) is straight-shaft or bent-shaft, there is a certain pressing force between the sliding shoe and the variable head, the cylinder and the distribution plate to ensure the sealing, and there is high-speed rotation. Restricted by "PV", it is difficult to design a large-displacement plunger pump (motor). Secondly, because the leakage between the cylinder body and the valve plate accounts for more than 70% of the total leakage, and it is easy to be strained by polluted particles, so This type of oil motor has poor low-speed performance, so low-speed high-torque motors generally do not use this structural mode

Embodiment Construction

[0013] See Figure 1 and Figure 2.

[0014] Swing plate slide valve flow distribution axial plunger pump, including front cover 2, housing 16, drive shaft 1, swing plate 4, plunger 6, flow distribution shaft 8, housing 16 is equipped with cylinder 9, cylinder 9 is installed with a distribution shaft 8, and the transmission shaft 1 rotates in the front cover 2. The transmission shaft 1 is movably connected with the swing plate 4 through a ball joint. The left end of the housing 16 is equipped with a swing seat 3. There is a spherical fit between them, and there is an oil drain port 10 on the housing 16. When the transmission shaft 1 rotates, the oscillating disc 4 swings in the oscillating seat 3, and the oscillating disc 4 and the plunger 6 are also flexibly connected by a ball hinge. 6 is located in the plunger hole 15 in the cylinder body 9. There is one undercut groove 12 on the plunger 6, and there are three left, middle and right undercut grooves 11, 13, 14 on the ring wal...

Abstract

The present invention discloses a wobble-disk type slide valve flow-distributing axial plunger pump (motor). It mainly includes the following several portions: front cover, shell body, cylinder body, driving shaft, wobble disk, plunger and flow-distributing shaft. Said invention also provides the concrete structure of the above-mentioned every portion and the connection mode of all the above-mentioned portions. Besides, said invention also provides the working principle of said plunger pump and its concrete operation method.

Description

technical field [0001] The invention belongs to an axial plunger pump (motor), in particular to an axial plunger pump (motor) with a wobble plate slide valve flow distribution. Background technique [0002] Whether the axial piston pump (motor) is straight-shaft or bent-shaft, there is a certain pressing force between the sliding shoe and the variable head, the cylinder and the distribution plate to ensure the sealing, and there is high-speed rotation. Restricted by "PV", it is difficult to design a large-displacement plunger pump (motor). Secondly, because the leakage between the cylinder body and the valve plate accounts for more than 70% of the total leakage, and it is easy to be strained by polluted particles, so This type of oil motor has poor low-speed performance, so low-speed high-torque motors generally do not adopt this structural mode. Contents of the invention [0003] The object of the present invention is to provide a wobble plate slide valve flow distributi...
