Problems solved by technology
At present, the plunger pump used in the closed circuit generally changes the output flow by changing the swing angle of the swash plate, which leads to a low flow adjustment speed of the entire drive circuit, which cannot meet the high speed response requirements of some actuators.

Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0016] Such as figure 1 As shown, the present invention includes a housing 1, an end cover 8, a flow distribution plate 6, a plunger cylinder 10, a plunger 11, a swash plate 13, and a rotating shaft 15. The end cover 8 is connected to the housing 1 through bolts 4 to form a The closed chamber of the hydraulic pump is formed; the left and right ends of the rotating shaft 15 are installed in the bearing chambers of the housing 1 and the end cover 8 through the second and first bearings 14 and 9 respectively, and the rotating shaft 15 is connected to the plunger through the second spline J2 The cylinder 10 is connected, and the plunger cylinder 10 forms nine plunger cavities 7 with nine plungers 11. The axis of the rotating shaft 15 intersects the axis of the swash plate 13 at an acute angle α, and the axes of the two are in the same plane, α =0...

The invention discloses a hydraulic pump with an oscillating swash plate and a rotary port plate and belongs to the technical field of hydraulic parts. The hydraulic pump comprises a shell, an end cover, a port plate, a plunger type cylinder, a plunger, a swash plate and a rotating shaft. The hydraulic pump is characterized in that the end cover is connected with the shell by a bolt; the rotating shaft is sequentially sleeved by the port plate, the plunger type cylinder and the swash plate from left to right; an oscillating motor rotor is connected with the port plate by a first spline; the swash plate is fitted with the shell by a revolute pair; each of the left and right sides of the upper end of the swash plate is connected with the shell by a reset spring and a swash plate driving cylinder; and each of a first oil hole and a second oil hole of the end cover communicates with a plunger cavity by a first kidney slot and a second kidney slot of the port plate, the first oil hole of the end cover is located in a third region of the end cover, the second oil hole of the end cover is located in a first region of the end cover, the counterclockwise rotation angle range of the port plate is 0-90 DEG, and the longitudinal sections Z-Z of the first kidney slot and the second kidney slot of the port plate are symmetric when the rotation angle of the port plate is equal to 0. The hydraulic pump has the advantage that the regulation speed of the output flow of the hydraulic pump is higher. Figure 1 serves as an abstract figure.
Description
technical field [0001] The invention belongs to the technical field of hydraulic parts, in particular to a hydraulic pump with a swing swash plate and a rotating flow distribution plate. Background technique [0002] Closed drive loops have great advantages in terms of energy savings. At present, the plunger pump used in the closed circuit generally changes the output flow by changing the swing angle of the swash plate, which leads to a low flow adjustment speed of the entire drive circuit, which cannot meet the high speed response requirements of some actuators. Contents of the invention [0003] The object of the present invention is to provide a hydraulic pump with a swing swash plate and a rotating valve plate, which can effectively overcome the problems in the prior art. The object of the present invention is achieved in this way, it comprises housing, end cap, flow plate, plunger cylinder, plunger, swash plate, rotating shaft, it is characterized in that: end cap is...
