UA47507C2 - Rotor-blades hydraulic motor - Google Patents

Abstract

Rotor-blades hydraulic motor contains a stator 1, in a central hole of which a rotor 2 with four half-cylinder blades 3, disposed as a cross, is inserted. To the rotor 2 cylindrical surface the rolls-lockers 4 are contacted, placed by a diameter opposed in the stator 1 slots. On the rolls-lockers 4 the two half-cylinder notches 5 are made on each, in parallel to the roll axis. The rotor 2 and the rolls-lockers 4 cinematically interconnected among them by a gear 8, they are made of polymer materials, and the rotor has a steel armoring.

Description

Description of the invention

The rotor-blade hydraulic motor belongs to mechanical engineering and can be used to 2 convert the energy of the fluid flow into mechanical energy.

The well-known roller-vane hydraulic pump /Application Mo98073766 dated 14.07.98/, which consists of a stator, in the central hole of which a rotor with four semi-cylindrical blades arranged in a cross pattern is installed, the cylindrical surface of the rotor is contacted by closing rollers placed diametrically opposite in the grooves of the stator, on each closing roller has two diametrically opposite 70 semi-cylindrical recesses parallel to the rotor axis, the rotor and closing rollers are kinematically connected by a gear, the transmission ratio of the gear and the ratio of the diameters of the closing rollers to the diameter of the rotor is 1:2, in the slots of the stator are equipped with cameras located on both sides of the plane that passes through the axis of the rotor and closing rollers, the cameras are connected to the inlet and outlet channels, non-return valves are installed in the channels connected to the cameras, covers are installed from the ends of the stator , which together 72 With the stator are tightened with bolts and nuts.

The disadvantages of such a roller-vane hydraulic pump are the relatively large mass of the rotor and closing rollers.

The basis of the invention "Rotor-blade hydraulic motor" is the task of reducing the weight of the hydraulic motor by making the rotor and locking rollers made of polymer materials and the rotor is forged from steel, which provides a significant reduction in the labor intensity and cost of manufacturing the hydraulic motor.

The rotor-blade hydraulic motor is schematically shown in section in Fig. 1, in Fig. 2 section along A - A in Fig. 1.

The rotor-blade hydraulic motor consists of a stator 1, in the central hole of which a rotor 2 is placed with four semi-cylindrical blades З arranged in a cross pattern, closing rollers 4 placed diametrically oppositely in the grooves of the stator 1, on each closing roller 4, contact the cylindrical surface of the rotor 2 made of two diametrically opposite depressions 5 parallel to the axis of the roller, c rotor 2, blades C and locking rollers 4 are made of polymer materials, shaft b and armature / rotor (3) are made of steel, rotor 2 and locking rollers 4 kinematic connection interconnected by a gear 8, which is placed in the recesses of the cover 9, in the covers 9 and 10 bearings 11 and 12 are installed, on which the necks of the rotor 2 and the necks of the closing rollers 4 rest, the stator 1, the covers 9 and 10 are tightened with bolts 13 and nuts 14, an oil seal 15 is installed in the cover 10, which covers the shaft 6. In the grooves of the stator 1, chambers 16 are made, placed on both sides of the plane that passes through the axes of the rotor 2 and the counter rollers hiccups 4, chambers 16 are connected to channels 17, 3 and 18, in which non-return valves 19, 20, 21, 22, 23 are installed - cavities of the hydraulic motor.

The rotary vane hydraulic motor works as follows. at

When the working fluid is supplied under pressure through the channel 17, the cavities 20 and 22 will be filled and the rotor rotates. 2 clockwise /fig.2/. From cavities 21 and 23, the working fluid will be pushed into the channel 18. From the 3rd channel 17, through the check valves 19, the working fluid is fed into the chambers 16, reducing the load on the necks of the locking rollers 4 and bearings 12. When the working fluid is supplied under pressure through the channel 18 the rotation of the rotor will be counter-clockwise.

The hydraulic motor is a reversible hydraulic machine. When a torque is applied to the shaft 6, the rotor 2 will rotate and work like a hydraulic pump. With p 50 Thus, the hydraulic machine can work as a hydraulic motor and as a hydraulic pump and is reversible.
