Abstract
Description
[0001] The utility model relates to hydraulic rotary motors.
[0002] The proposed hydraulic rotary motor can be used effectively in industry, the energy sector and agriculture.
[0003] A hydraulic motor known from the prior art (patent RU 2295062 F04C 2 / 44, F03C 2 / 30) comprises a housing, a rotor, control slides or control valves pivotally attached to the rotor, a slide deflector fixed to the housing, as well as two inlet channels and two outlet channels.
[0004] One disadvantage of such a hydraulic motor is that the lack of a seal between the valves and the housing creates a gap that inevitably widens during operation, leading to increased leakage and significant energy losses. The inefficient release of unused energy from the two outlet channels during rotor rotation indicates the low efficiency of the hydraulic motor. Friction during rotation and valve deflection also results in energy losses. These energy losses further reduce the efficiency of the hydraulic motor, which has a complex design.
[0005] The closest possible example of the hydraulic rotary motor proposed herein is a pneumatic rotary motor known from patent SU 1583643 (F01C 1 / 344). This pneumatic rotary motor has a housing, a cylindrical rotor with projections and a shaft arranged concentrically inside the housing, two working chambers, a valve and a separating plate with springs in the lower region, as well as inlet and outlet channels.
[0006] Disadvantages of such a pneumatic rotary motor, which serves as a prototype, include its low efficiency and the complexity of its design. The gap between the inner part of the pneumatic rotary motor housing and the rotor projections causes leakage and energy loss. The friction of the protruding rotor against the separating plate with each rotation of the shaft-rotor pair wears down the rotor projections and increases the gap between the housing and the rotor projections, leading to increased leakage and greater energy loss. To open the inlet port for each cycle, the rotor must overcome the resistance of two springs located in the lower part of the separating plate and the valve, resulting in energy loss. When the rotor projections contact the outlet port, the energy concentrated in the working chamber is released unused to the outside. Such a pneumatic rotary motor has a complex construction.The aforementioned disadvantages lead to a low efficiency of the pneumatic rotary motor.
[0007] The purpose of the utility model is to provide a hydraulic rotary motor with a simple design and high efficiency.
[0008] This task is solved by the proposed hydraulic rotary motor.
[0009] The causal relationship with the totality of features of the present utility model lies in the fact that, when the valve of the pressure vessel is opened, the fluid pressure is transmitted through the fluid into the four chambers of the hydraulic rotary motor, which are in the form of straight prisms with a triangular cross-section. A large pressure force acts on the bottom surfaces of the radially arranged chambers, which are in the form of straight prisms with a triangular cross-section, thereby generating a strong torque and producing mechanical energy. According to the law of conservation of energy in closed systems, this process continues until the energy supply is stopped and the pressure in the chambers decreases. This results in the high efficiency of the hydraulic rotary motor while maintaining a simple design.
[0010] Inside the rotor of the proposed hydraulic rotary motor, prismatic chambers of equal size are formed by sealing both rotor ends with flanged sleeves. These chambers, which are connected to the power source, have the same length as the rotor and are arranged parallel to its central axis. An annular channel is open along the circumference of the rotor's upper surface, with sealing rings on its sides. This annular channel connects to the power source via an opening in the housing. The prismatic chambers connect to the annular channel via openings in their upper sections. The bottom surfaces of the prismatic chambers are arranged radially at equal angular intervals from one another.
[0011] The proposed hydraulic rotary motor has a simple design and high efficiency. It can be used efficiently in industry, energy, and agriculture. The hydraulic rotary motor possesses positive characteristics that significantly distinguish it from known motors. Its practical application makes it eligible for utility model protection.
[0012] The subject matter of the utility model is explained in the accompanying drawings. They show: Fig. 1 a longitudinal section of the hydraulic rotary motor. Fig. 2. The cylindrical rotor in a sectional view:
[0013] Inside housing 1 of the hydraulic rotary motor ( Fig. 1) A cylindrical rotor 3 is mounted on the shaft 2, which can rotate concentrically. Inside the rotor 3 are four open prismatic channels 4 (see Fig. 2) of the same size, extending in a straight line and having a triangular cross-section, the same length as the rotor, and arranged parallel to its central axis. The chambers, in the form of straight prisms 6 with a triangular cross-section, are formed by closing both ends of the rotor 3 with flanged sleeves 5. A seal (not shown) is provided between the rotor 3 and the flanged sleeves 5. The flanged sleeves 5 are connected to the shaft 2 via conical pins 7. A channel 9 with a U-shaped cross-section is recessed in the central area of the top surface of the rotor 3, with sealing rings 8 on its sides to prevent leakage. The annular channel 9 is connected to a power source (not shown) via a horizontal opening 10 in the housing 1. The inlet valve 12 is connected to the annular channel 9 via a vertically extending opening 11 provided in the housing 1.The chambers, in the form of rectilinear prisms 6 with triangular cross-sections, are connected to the annular channel 9 via openings 13 that open perpendicularly to their base surfaces in their upper parts. The base surfaces of the chambers, in the form of rectilinear prisms 6 with triangular cross-sections, are arranged radially at 90-degree intervals from one another. The ball bearings 15, mounted on the shaft 2, are arranged within socket-shaped flange covers 14, which are attached to the sides of the housing 1. The openings of the flange cover 14 with flange sockets are closed with flange caps 16. The hydraulic rotary motor is equipped with a liquid cooling system (not shown).
[0014] The hydraulic rotary motor works as follows:
[0015] The hydraulic rotary motor ( Fig. 1) is filled with a liquid. When the valve of a reservoir or collection container is opened, the liquid pressure generated in the reservoir or collection container is admitted through the horizontal opening 10 in the housing 1 and through the openings 13 in the central part of the annular channel 9 with a U-shaped cross-section into the four chambers in the form of straight prisms 6 with a triangular cross-section, which are formed inside the cylindrical rotor 3. A large pressure force acts on the bottom surfaces of the radially arranged chambers in the form of straight prisms 6 with a triangular cross-section, thereby generating a strong torque and producing mechanical energy. The hydraulic rotary motor ( Fig. 1) is able to transfer the generated mechanical energy to machines and mechanisms. The constant application of the pressure force to the undersides of the radially arranged chambers in the form of straight prisms 6 with a triangular cross-section results in the high efficiency of the hydraulic rotary motor ( Fig. 1) This process continues until the energy supply is interrupted and the pressure inside the chambers drops. Sealing rings 8, located in one of the annular channels 9 with a U-shaped cross-section, prevent fluid from escaping. When the energy supply is interrupted, the pressure in the hydraulic rotary motor is controlled or regulated via the valve 12, which is connected to the vertically extending opening 11 in the housing 1 ( Fig. 1) The liquid cooling system makes it possible to maintain an optimal temperature in the hydraulic rotary motor.
[0016] The causal relationship with the totality of features of the present utility model lies in the fact that, when the reservoir or collection container valve is opened, the fluid pressure is transmitted through the fluid into the four chambers of the hydraulic rotary motor, which are shaped like straight prisms with a triangular cross-section. This exerts a large pressure force on the bottom surfaces of the radially arranged chambers, generating a strong torque and thus mechanical energy. According to the law of conservation of energy in closed systems, this process continues until the energy supply ceases and the pressure inside the chambers decreases. This results in the high efficiency of the hydraulic rotary motor while maintaining a simple design.
[0017] The proposed hydraulic rotary motor has a simple design and high efficiency. It can be used effectively in industry, energy, and agriculture. The hydraulic rotary motor possesses positive characteristics that significantly distinguish it from conventional motors. Its practical applicability allows it to be considered a utility model.
[0018] In summary, this utility model relates to hydraulic rotary motors. The purpose of the utility model is to provide a hydraulic rotary motor with a simple design and high efficiency. This purpose is achieved by the proposed hydraulic rotary motor. Inside the cylindrical rotor are chambers in the form of straight prisms with a triangular cross-section and of the same size, which have the same length as the rotor, are arranged parallel to its central axis, and are connected to a power source. The chambers, in the form of straight prisms with a triangular cross-section, are created by closing both ends of the rotor with flanged sleeves. On the upper surface of the rotor, an annular channel with a U-shaped cross-section is open along the circumference, and sealing rings are provided on its sides.The central part of the annular channel with a rectangular cross-section is connected to the power source via an opening in the housing. The chambers, in the form of rectilinear prisms with a triangular cross-section, are connected to the central part of the annular channel with a U-shaped cross-section via openings in their upper sections that run perpendicular to their base surfaces. The base surfaces of the chambers, also in the form of rectilinear prisms with a triangular cross-section, are arranged radially at 90-degree intervals. The proposed hydraulic rotary motor is practically applicable, making it eligible for utility model protection.
