Description

Изобретение огаоситс к области машиностроени и может быть использовано во всех отрасп х. народного хоз йства в системах смазки и гищюприводах машин.The invention relates to the field of mechanical engineering and can be used in all fields. national economy in the lubrication systems and the gist drives of machines.

Известен роторный гидродвигатель, содержаний Профилированный ротор, шиберы, расположенные в пазах корпуса, всасывающие и нагнетательные полости {1 .Known rotary hydraulic motor, contents. Profiled rotor, gate valves located in the housing grooves, suction and discharge cavities {1.

Недостатком указанного гидродвигател вл етс то, что в процессе работы поверхность ротора изнашиваетс и зазор между рртором н корпусом увеличиваетс настолько,что жидкость из полости нагнетени проходит в полость всасывани , вследствие чего давление, создаваемое насосом, падает, а вышедший из стро гидродвигатель требует частых ремонтов.The disadvantage of this hydraulic motor is that during operation the surface of the rotor wears out and the gap between the rotor and the housing increases so that fluid from the discharge cavity passes into the suction cavity, as a result of which the pressure created by the pump drops and the outdated hydraulic engine requires frequent repairs .

Цель изобретени - повышение надежности гидродвигател .The purpose of the invention is to increase the reliability of the hydraulic engine.

Это достигаетс тем, что в роторе выполнены сквозные отверсти , заполнезшые гидропласгом , и соединенна с последним осева проточка с поджимным винтом дл взаимодействи с гидропластом. Такое вьшолнение уст ройства позвол ет передавать давление, создаБаемое поджимным винтом, на тонкие стен- ки ротора дл отжима их и выбора зазора между ротором и корпусом.This is achieved by the fact that the rotor has through holes, filled with a hydroplasm, and an axial groove connected to the latter with a gland screw for interacting with the hydroplast. Such an implementation of the device allows the pressure generated by the gland screw to be transferred to the thin walls of the rotor to squeeze them and select a gap between the rotor and the housing.

На фиг. 1 изображен гидродвигатель, продольный разрез; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a hydraulic motor, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

Гидродвигатель содержит корпус 1, виутри которого вращаетс в подшипниках 2 профилированный ротор 3. Шиберы 4 радиально перемещаютс в пазах 5 корпуса 1 насоса, раздеto л рабочую полость на полость Б всасываН1Ш и полость В нагнетени . Пружины 6 поджимают шиберы 4 к ротору 3, а регулировочные винты 7 регулируют усилие поджати их.The hydraulic motor includes a housing 1, the rotor of which rotates in bearings 2 a profiled rotor 3. Gates 4 radially move in the slots 5 of the pump housing 1, divide the working cavity into the cavity B of the suction side and the pressure cavity B. The spring 6 presses the gates 4 to the rotor 3, and the adjusting screws 7 regulate the force to press them.

В роторе 3 выпол1{ены сквозные отверсти 8, заполне1шые гидропластом 9, и соединённа с последним осева проточка 10 с поджим-1 ным винтом 11, который осуществл ет давление In the rotor 3, there are: through holes 8, filled with hydroplast 9, and axial bore 10 connected to the last one with a one-second screw 11, which exerts pressure

Claims

20 through the hydroplast 9 and the thin walls of the rotor 3. In the covers 12 of the housing 1, rubber sealing rings 13 are placed. The flanges 14 are fastened with screws 15 to the rotor 3 with two hydraulic filled pipes, closing the hole with the reservoir. . The technological holes formed during the drilling of the connecting holes are closed with plugs 16. When the rotor 3 rotates clockwise, the cavity between one of its protrusions and the gate 4 increases, in which a vacuum is created and where the liquid rushes. Then, a certain volume of fluid is cut off with two protrusions of the rotor 3 and is transferred circumferentially to the second gate 4, as a result of which the volume of the injection cavity B decreases. The fluid is injected into the system under pressure. In the motor mode, the fluid is pressurized into the strips B, exerting pressure on the surface of the rotor 3 and driving it into rotation. The speed of rotation of the rotor 3 is controlled by changing the gap between the profiled torus 3 and the cylindrical body 1 by rotating the gland screw 11, the force of which is transmitted through the hydraulic layer 9 filling the through holes 8 in the rotor 3, thereby pressing its thin walls. The use of the proposed design makes it possible to use it for a long time without repair, improving reliability in operation and simplifying repair. Claims of a rotor hydraulic motor comprising a profiled rotor, gates located in the housing grooves, suction and discharge cavities, characterized in that, in order to increase the reliability of the hydraulic motor, through holes made with a hydraulic layer are made in the rotor and connected to the last axial groove with a compression screw to interact with hydroplast.
