Embodiment
As shown in Figures 1 to 8,
A valve plate-type oil hydraulic motor, is comprised of shell 1, rotor 2 and stator 3.1 two housings of its housing form by screw 13 is fastening, form one for holding the cavity of stator and rotor.
There is an eccentric cavity stator 3 inside, use steady pin 4 fixing between stator 3 and shell 1.Rotor 2 is arranged in the cavity of shell, and forms an airtight irregular hydraulic pressure cavity 5 with stator 3 inwalls, wherein passes in and out oilhole (61,62) and communicates with oil duct (51,52), and nearby arrange and delay nip territory (71,72).Rotor portion is comprised of master unit (Fig. 4) and accessory (Fig. 5) parts, and by socket head screw 9, is tightened to one between the two, and with outer casing inner wall between by bearing 8, coordinate, make to relatively rotate.On master unit 21, there is an output shaft 22 and a crosswise valve block groove 23, and be provided with the projection 24 of thick use surely in valve block groove one side, in accessory 25, be provided with the valve block groove 23 ' and the fitting surface 26 that are oppositely arranged with master unit, after coordinating, use socket head screw to carry out fastening, in valve block groove 23, have and hold the passage that valve block 11 slides, and between valve block facing each other, use knock-out spring 10 to carry out pretension, the outer end of such two valve blocks that are oppositely arranged 11 keeps close contact with inwall all the time, no matter how rotor rotates, valve block and stator inner wall are all the time in best fit state.In valve block 11 outer ends with inwall contacting point, be provided with a C shape groove, and in this C shape groove, roller 12 be installed, form substantial rolling friction, make it friction and greatly reduce.Note there is point of intersection between two pairs of above-mentioned valve blocks, thus at the transition portion of infall setting, should there is three dimensional intersection effect, can be with reference to the pattern in figure 6 and Fig. 7.
During specific works, the high pressure oil providing for oil hydraulic motor by high-pressure service pump, flow into turnover oilhole 61, then by oil duct 51 Inner, through slow nip territory 71, enter in hydraulic pressure cavity 5, high pressure oil promotes valve block again, thereby rotor 2 is turned clockwise, and generation torque rotor driven and output shaft acting produce mechanical energy.High pressure oil is pulled to slow nip territory 72 at hydraulic pressure cavity Inner, enters oil duct 52, then from turnover oilhole 62, flows out, and completes a revolution.Otherwise high pressure oil flows into turnover oilhole 62, drive rotor 2 is rotated counterclockwise work, and last high pressure oil flows out and finishes the work from turnover oilhole 61, and formation rotates backward.
The rotating speed of this rotor is decided by the uninterrupted of input hydraulic pressure motor, can under lower hydraulic driving, export higher rotating speed.The system energy clockwise and anticlockwise of this motor, coordinates and stronger sealing for guaranteeing that valve block and inner casing inwall hold out against, between valve block, be provided with knock-out spring, and at valve block two ends, roller be installed, larger minimizing friction, thereby improved sensitivity and working efficiency.This motor stator and shell are fixed by steady pin, the oil duct and the slow joint area of pressing that on shell, have two turnover oilholes and stator, on rotor, there is valve block groove, valve block rotation with rotor in valve block groove is slided, between valve block, be provided with knock-out spring, can make valve block in hydraulic pressure cavity, hold out against to coordinate with inner casing inwall all the time and finish the work.The friction that bearing reduces them is installed between rotor and shell, in shell and outer housing cover, seal ring is housed, make rotor in the hydraulic pressure cavity of a sealing, and rotation that can reciprocation cycle, thereby transmit mechanical energy after acting, finish the work.
Except the technical characteristics described in specification, be the known technology of those skilled in the art.
