Description

(54) PLASTIC HYDRAULIC MACHINE.

one

The invention relates to mechanical engineering and can be used in hydraulic drives of machines for industrial use.

Lamellar hydraulic machines are known, comprising a housing, a rotor, blades, plates, a shaped stator ring, and distribution discs. These hydraulic machines for raising the feed (torque) are usually repetitive and are unregulated 4 and l}.

Also known is a plate-type hydraulic machine containing a stationary body with krieaks and suction pipes and pressure cavities, plates installed in body slots parallel to the axis of rotation of the rotor, a rotor with end profiles of the surfaces and working chambers formed by a shaped end surface of the rotor, and surfaces plates and housing 2,

A disadvantage of the known plate hydraulic machine is the lack of feed adjustment (torque ms leite).

The purpose of the invention is to create a plate hydraulic machines of multiple

action with adjustable feed (torque).

The goal is achieved by the fact that the cover is installed in the housing with the possibility of angular movement and is provided with radial openings connecting the pressure and suction chambers through an annular groove made in the housing. .

FIG. 1 shows a general view of the plasticine hydraulic machine) in FIG. 2, section A-A in FIG. 1 on the working hook “with the rotary cover in the extreme position; in fig. Figure 3 shows a ratchet profile of the end of the rotor and the housing with plates, control valves and openings placed in it.

The plate-type hydraulic machine includes a housing 1, a rotor: with: profiled end surface, a crest 3 installed in the housing with possible angular displacement on bearings 4, plates 5 placed in slots 6 of the housing with axial movement in them under the action of spring 7. On the inner cylindrical the surfaces of the housing are radial holes 8, connected by axial drillings 9 with a common annular suction cavity 10 connected through an inlet 11 in Flange 12, with a suction pipe. In addition, on the inner cylindrical surface of the housing 1 are located radial holes 13, connected by axial hornings 14 with a pipe 15 of the discharge pipeline, and annular grooves 16. In the cap there are radial holes 17 18 that communicate through the channels 16 19 and 20 and all syvyak ::. In the pump mode, plate hydraulic machines operate as follows. When the rotor 2 rotates from the drive motor, the plates 5, located in the slots 6 of the housing 1 and constantly, pressed by the springs 7 to the profiled end surface of the rotor, make a periodic change in the volume of the chamber cavities 19 and 20 injection and suction. In this case, the working fluid from the injection chamber through the radial hole 13, the axial drills 14 and the nozzle 15 is displaced into the discharge pipeline, at the same time the working fluid enters the suction chamber through the radial holes 8 by axial drilling 9 and the end cavity 10 from the suction nozzle 11 in the flange 12. The maximum pump flow corresponds to the sum of the fluid supply from all working pressure chambers and is determined by the position of the cover 3, at which the holes 17 are the most distant from the plates. In this case, after overlapping the profile of the end profiled surface of the rotor of the openings 17, the entire injection chamber is displaced into the discharge cavity 19. When the feed is reduced, the cover 3 mounted on the bearing 4 rotates and is set to a position where the opening 17 is less than at maximum feed, distance from plates. In this case, the overlapping of the openings 17 by the projections of the profile of the end surface of the rotor occurs later and only part of the volume of the injection chamber is displaced into the discharge cavity, and the other part of the liquid through the holes 17 and 18 and the annular groove 16 When the plate-type hydraulic machine operates in the hydraulic motor mode, the pressurized fluid is poured into the chamber and the fluid energy is converted into a torque, while the torque value can be adjusted by moving the cover 3.. The ability to control the feed (torque) in plate machines with multiple actions greatly expands their field of application and increases the overall efficiency of the hydraulic drive. The invention of the Plate Hydromachine, comprising a housing with plates installed in its grooves, a lid, a rotor with a profiled end surface forming a lid between the latter and the plates of the injection and suction chambers, in order to regulate the flow (torque) in the housing with the possibility of angular movement and provided with radial holes connecting the injection and suction chambers through an annular groove made in the housing.
