Изобретение относитс к обработке металлов давлением, конкретно к конструкци м гидромоторов дл привода БИНТОВЫХ прессов.The invention relates to the processing of metals by pressure, specifically to the design of hydraulic motors for driving BINT presses.

Известен гидромотор дл привода винтового пресса, содержащий силовой блок, выполненный в виде установленного на станине пресса статора , во внутренней полости которого размещены закрепленный на винте ротор с подвод щими каналами, соеданенными с напорной и сливной гидролини ми, а также вытеснители 1.A hydraulic motor for driving a screw press is known, which contains a power unit made in the form of a stator mounted on a press frame, in the internal cavity of which a rotor mounted on a screw with supply channels connected to pressure and drain hydrolines and displacers 1 are placed.

Вращение винта осуществл етс при помощи такого гидромотора, соединенного гидравлически с насосной силовой установкой, а реверс винта - за счет изменени направлени вращени ротора.The rotation of the screw is carried out with the help of such a hydraulic motor connected hydraulically to the pumping power plant, and the reverse of the screw due to a change in the direction of rotation of the rotor.

Однако при больших ускорени х и частых реверсах в крайних мертвых точках детали и узлы гидромотора быстро изнашиваютс . Кроме того, имеет место повышенный расход мощности .However, with large accelerations and frequent reversals at the dead spots, the parts and components of the hydraulic motor wear out quickly. In addition, there is an increased power consumption.

Целью изобретени вл етс снижение мощности привода и повышение срока службы гидромотора .The aim of the invention is to reduce drive power and increase the life of the motor.

В предложенном гидромоторе цель достигаетс за счет того, что он снабжен дополнительным блоком, содержащим статор с размешенным в его полости ротором с подвод щими каналами, а также вытеснител ми, при этом статор дополнительного блока установлен на станине пресса соосно со статором силового блока, а его ротор закреплен на винте. На роторах силового и дополнительного блоков выполнены профильные пазы, плоскости которых параллельны его оси, а вытеснители выполнень в виде поворотных лопаток и шарнирно закреплены в статорах силового и дополнительного блоков с возможностью взаимодействи с плоскост ми профильных пазов роторов, при этом образуютс замкнутые полости, соединенные подвод щими каналами ротора с напорной и сливной шдролинн ми.In the proposed motor, the goal is achieved due to the fact that it is equipped with an additional unit containing a stator with a rotor placed in its cavity with supply channels and also displacers, while the stator of the additional unit is mounted on the press frame coaxially with the stator of the power unit, and the rotor is fixed on the screw. On the rotors of the power and additional blocks, profile grooves are made, the planes of which are parallel to its axes, and the displacers are made in the form of rotating blades and hinged in the stators of the power and additional blocks with the ability to interact with the planes of the profile grooves of the rotors, thus forming closed cavities, connected in rotor channels with pressure and drainage pipes.

Claims

The hydromotor contains a power I and an additional 2 blocks, the stators of the hocks are mounted in the base 3 of the screw press. In each block are placed the rotor 4 mounted on the screw 5, as well as displacing the b, made in the form of rotating blades pivotally mounted in the stator. In the rotor 4, profiled grooves 7 are made, with the help of which the rotor is divided into separate sectors. The inclined planes of the 8 grooves during operation interact with the displacers 6 In each sector of the rotor there are feed channels 9. The power unit 1 is designed to rotate the screw in one direction, and with the help of the additional unit 2 it rotates the screw in the other direction, for the displacers 6 and the inclined planes of the core slots 7 of the rotor in the additional block are turned in the opposite direction relative to the axis of the rotor motor. The rotor is rotated from a pressure source 10 connected through distribution devices 11 and 12, pipelines 13 and 14, and supply channels 9 with closed hydraulic cavities 15. When the displacers come off from the inclined plane 8, the cavity between this and the next blades connects With plum. The motor operates as follows. When the screw is rotated in one direction, the pressure source 10 is connected through the distributor to the closed hydraulic cavities 15 of the power unit 1. Pressure is applied to the inclined plane 8, the resultant force of which creates a moment relative to the axis of rotation of the screw. As a result, the screw 5 begins to rotate, thereby making a working stroke. At the same time, when the extrusion end of the body 6 slides along the plane of the sector, an additional moment is created due to the fluid pressure on the blade area. In order to rotate the screw in the; frost side (for perfect reversal), an additional block 2 is connected to the pressure source, which operates similarly to block 1 but creates a torque in the opposite direction.
