Hydraulic power machine

Abstract

The invention discloses a hydraulic power machine. The hydraulic power machine comprises a rotating shaft on a machine base (6), and a hydraulic pump (1), a liquid distributing pipe (2) and a liquid distributor (3) which are connected with one another in turn, wherein the machine base (6) is provided with a basic shaft (18) in movable fit with more than two hydraulic cylinders (5); the bottom parts of inner cavities of the hydraulic cylinders (5) are provided with one-way valves (21) which are connected with a liquid feed pipe (4) and a liquid return pipe (9) respectively; the liquid feed pipe (4) is connected with the liquid distributor (3); a center shaft parts of the hydraulic cylinders (5) are sleeved and sealed and are in movable fit with a piston rod (17); the rotating shaft is a crank shaft (7) which is in movable fit with the piston rod (17) and is coaxially connected with a liquid distributor shaft core (11); and the liquid distributor (3) comprises a liquid distributor jacket (10) of which the inner wall is provided with an annular liquid distributing groove (13) and a half-annular liquid distributing groove (12), and also comprises the liquid distributor shaft core (11) which is in movable fit connection with the liquid distributor and is internally provided with a liquid storage cavity (16), a liquid inlet hole (14) and a liquid outlet hole (15). The hydraulic power machine can convert hydraulic energy into mechanical energy.

Description

technical field [0001] The invention relates to a power machine, especially a hydraulic power machine. Background technique [0002] The hydraulic power machine, also known as the hydraulic motor, is a working device that converts hydraulic energy into mechanical energy. It outputs mechanical energy through rotational motion to obtain the rotational speed and torque on the output shaft. At present, there are various forms of hydraulic motors used by people, such as gear type, vane type, plunger type and so on. These hydraulic motors all have shortcomings. First, the structure is relatively complex, and the manufacturing precision is high and difficult, resulting in high production costs; secondly, the maintenance and repair during use are also difficult, and the use cost is difficult to reduce; Again, due to the different requirements of the users, the requirements for the speed and torque of the hydraulic motor are also different. For this reason, there are hydraulic motor...

Problems solved by technology

These hydraulic motors all have shortcomings. First, the structure is relatively complex, and the manufacturing precision is high and difficult, resulting in high production costs; secondly, the maintenance and repair during use are also difficult, and the use cost is difficult to reduce; Again, due to the different requirements of the users, the requirements for the speed and torque of the hydraulic motor are also different. For this reason, there are hydraulic motors of various forms and specifications on the market. Up to now, there is no one The hydraulic motor can take into account both the speed and the torque in a wide range, so that it has strong applicability; finally, because the hydraulic motor will produce components that do not directly perform work and excessive power conversion friction during the hydraulic movement, reducing the effectiveness of hydraulic pressure
