Изобретение относитс к гидромашиностроению , в частности к аксиально-порглневым гадромашинам с регулируемой величиной объемной подачи.This invention relates to a hydraulic engineering industry, in particular to axial-hydraulic hydrodynamic hydrodynamic machines with an adjustable feed rate.

Известна сдвоенна аксиально-поршнева гидромашина, содержаша корпус с крышкой и размешенными в нем с возможностью поворота двум люльками блоков цилиндров, св занными между собой пластиной, устройство дл регулировани объемной подачи гидромашин , включаюшее регул тор мощноста в виде ступенчатого плунжера, св зашюго с подпружиненным направл юшим стержнем, имеюшим хвостовик и головку, причем последн при помоши штьф и ролика св зана с пластиной 1.A double axial piston hydraulic machine is known, containing a housing with a lid and two cradles of cylinder blocks, which can be rotated there, can be rotated by a plate, a device for controlling the volumetric flow of hydraulic machines, including a stepped plunger power regulator, connected with a spring-loaded direction You have a rod with a shank and a head, the latter with the help of the pin and the roller connected with the plate 1.

В известной гидромашине отсутствует средства , поЗвол юшие осуществл ть дистанцион- ное или ручное управление величиной объемной подачи гидромашины, что сушественно ограничивает область ее применени .In the known hydraulic machine, there are no means to allow remote or manual control of the volume of the supply of the hydraulic machine, which essentially limits its scope.

Целью изобретени вл етс расширение функшюнапьных возможностей гидромашины.The aim of the invention is to expand the functional capabilities of the hydraulic machine.

Эта цель достигаетс тем, что гидромашина снабжена зубчатым колесом, втулкой и охватываюшим ее барабанным кулачком с винтовым пазом, и закрепленным на крышке подпружиненным гидроцилиндром с зубчатой рейкой, при этом зубчатое колесо установлено в корпусе гидроцилиндра, св зано с хвостовиком стержн и входнт в зацепление с рейкой гидроцилиндра, втулка и кулачок при помоши штыр закреплены на го10 ловке направл юшего стержн , а ролик закреплен в пластине дл взаимодействи с винтовым пазом кулачка.This goal is achieved by the fact that the hydraulic machine is equipped with a gear wheel, a bushing and a drum cam surrounding it with a screw groove, and a spring-loaded hydraulic cylinder with a gear rack mounted on the lid, while the gear wheel is installed in the hydraulic cylinder body, connected to the stem of the rod and engages With the help of the cylinder ram, the bushing and the cam, with the help of the pin, are fixed to the end of the guide rod, and the roller is fixed in the plate for engagement with the screw groove of the cam.

Дл осушествлени ручного управлени For manual operation

IS гидромашиной в корпусе гидроцилиндра установлен снабженный руко ткой вал с шестерней , вход шей в зацепление с зубчатым колесом.An IS hydromachine in the cylinder case is fitted with a shaft equipped with a gear and a gear wheel, and the inlet of the neck is engaged with the gear wheel.

Claims

FIG. 1 shows a hydraulic machine, 20 times cut across the adjustment unit; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 3. The dual axial-piston hydraulic machine comprises a housing 1 with two cradles 3 interconnected by a plate 2, cradles 3 carrying cylinder blocks that can be rotated therein. The plate 2 is fixed on the axis of the roller 4, which enters the screw groove 5 of the drum cam 6 mounted on the sleeve 7 and fixed to the head of the guide rod 8 using shtyr 9. The hydraulic compartment is equipped with a power regulator that includes a stepped plunger 10 installed in the sleeve 11. The plunger 10 through the washer 12 is connected to the spring-loaded springs 13 by the guide rod 8. The shank of the guide rod 8 is provided with splines 14 (keyway) between it and the lid 15 is positioned to form a splined (keyed) connection gear wheel 16, s the kill of which engages with the teeth of the rail 17 fixed on the lid 15 of the hydraulic cylinder 19 spring-loaded 18, having the plunger 20, contacting the rail with the rack 17. The gear-gear shaft 22 equipped with the handle 21 is fitted with the handle 21 The gear fluid from the pump sections is supplied to the power controller through the holes 23 and 24. The pressure for remote control of the hydraulic machine. Connect the hydraulic cylinder 19 through the hole 25. The hydraulic machine works as follows. Under the action of the springs 13, the guide rod 8, through the cam 6, acts on the roller 4 and moves the cradle 3 to the extreme position corresponding to the largest working volume of the pump sections. With an increase in pressure developed by the hydromachine, the plunger 10 acts on the washer 12 and, compressing the spring 13, moves the cradle 3 in the direction of the reduced displacement of the pump sections. If necessary, remote control of the hydraulic machine, the working fluid under pressure through the opening 25 is supplied to the hydraulic cylinder 19, the plunger 20 of which acts on the rail 17. Moving the rail 17 causes the gear wheel and the guide rod 8 connected with it to rotate, the cam 6 of which acts like a screw groove 5 on the roller 4 and moves the cradle 3 to the desired position. If manual operation is necessary, the handle 21 of the gear shaft 22 is interacting. As a result of the interaction of the gear 22 with the wheel 16, the rod 8 and the cam 6 are rotated with a screw groove 5 and the cradles 3 to the required position. Thus, the hydroshaped machine has a power controller and means for remote and manual control, which significantly expands its field of application. Claim 1. A dual axial piston hydraulic machine comprising a housing with a lid and accommodated therein that can be rotated by two cradles of cylinder blocks interconnected by a plate, a device for controlling the volumetric supply of hydraulic chambers, including a power regulator in the form of a stepped plunger connected with a spring-loaded guide rod having a shank and a head, the latter being connected with a plate by means of a pin and a roller, characterized in that, in order to expand the functional possibilities The hydraulic machine is equipped with a gear wheel and a sleeve and a drum cam surrounding it with a screw shaft, and a spring-loaded hydraulic cylinder with a gear rack mounted on the lid, while the gear wheel is installed in the hydraulic cylinder housing, which is connected to the shank of the rod and engages with the cylinder rod, sleeve and the cam is fastened to the head of the guide rod with a pin, and the roller is fixed in the plate to interact with the screw groove of the cam.

2. The hydraulic machine according to claim 1, characterized in that the shaft of the hydraulic cylinder is equipped with a shaft equipped with a handle with a gear that engages with a gear wheel.
