summary of the invention
The technical problem to be solved in the present invention is to solve above-mentioned deficiency, and provide one to be applicable to rotating band control function actuator vane motor structure, this structure can solve it completely and because circuit winding actuator can only do the limited number of turns, cannot be rotated in place in actual application, after each execution, all need empty acting once to untie the circuit of winding, the control wiring life-span easy to wear is short, the difficult problems such as maintenance cost height, improved greatly the using scope of vane motor, and user does not need to consider how to design the associated components such as control wiring solution again, thereby reduced user and used difficulty and processing cost.
Technical solution of the present invention is, a kind of antiwind rotary hydraulic motor structure is provided, comprise output shaft, front case, stator-rotator pair, rear case, the rear end of described rear case is provided with system oil-feed port, described system oil-feed port is divided into filler opening I and return opening, described system oil-feed port also comprises filler opening II and return opening II, in described rear case and output shaft, be provided with oil input channel and the back oil road of mutual noninterference, described output shaft is provided with the filler opening and the return opening that are communicated with respectively with oil input channel and back oil road.
As preferably, the outer of described output shaft placed respectively along being circumferentially with ring-type oil input channel distributing groove and back oil road oil-return groove, described ring-type oil input channel distributing groove is connected with described output shaft fuel feeding filler opening, and described ring-type back oil road oil-return groove is connected with described output shaft oil return oil outlet.
As preferably, described in-line and back oil road are parallel to each other.
The present invention is owing to directly changing output shaft, housing, all that simple modification optimized, but creationary pilot line and the actuator rotary synchronous problem of having solved, and client is without considering how to design again control wiring associated components, guaranteeing under the prerequisite of geometric accuracy, user is easy to install and use, reduces time and the expense of maintenance system, reduces the loss bringing because safeguarding; And very easily realize the rotation of the unlimited number of turns, improved greatly using scope, the efficiency of vane motor.

Embodiment
Below in conjunction with accompanying drawing 1, the embodiment of a kind of antiwind rotary hydraulic motor structure of the present invention is described in detail below, should be understood that following embodiment is to most preferred embodiment of the present invention, not as limitation of the present invention.
As shown in accompanying drawing 1 to Fig. 5, a kind of antiwind rotary hydraulic motor structure, comprise output shaft 1, front case 3, stator-rotator pair 4, rear case 5, the rear end of described rear case 5 is provided with system oil-feed port 6, described system oil-feed port 6 is divided into filler opening IC and return opening D, it is characterized in that: described system oil-feed port 6 also comprises filler opening IIA and return opening IIB, in described rear case 5 and output shaft 1, be provided with oil input channel A1 and the back oil road B1 of mutual noninterference, described output shaft 1 is provided with the filler opening A2 and the return opening B2 that are communicated with respectively with oil input channel A1 and back oil road B1.
In the present embodiment, the outer of described output shaft 1 placed respectively along being circumferentially with ring-type oil input channel distributing groove and back oil road oil-return groove, described ring-type oil input channel distributing groove is connected with described output shaft fuel feeding filler opening A2, and described ring-type back oil road oil-return groove is connected with described output shaft oil return oil outlet B2.
Wherein, described in-line A1 and back oil road B1 are parallel to each other.
Specific works principle, by revolution motor actuator port C and D, realized, suppose that C hydraulic fluid port enters high pressure oil, D hydraulic fluid port is return opening, now high pressure oil is entered by C hydraulic fluid port, through housing shunting, enters respectively in the C1 and C2 chamber of stator-rotator pair, promoting blade rotates in the counterclockwise direction, thereby drive output shaft to be rotated counterclockwise, along with the rotation of blade, D1 and D2 chamber diminish, unnecessary fluid to D hydraulic fluid port oil sump tank, completes each working stroke through housing, vice versa, realizes turning clockwise of output shaft, output shaft drives driven member rotation, the fixture of driven member is assumed to be oil cylinder and will works, itself is with driven member synchronous rotary, the entering of oil cylinder, return opening are connected with A1 hydraulic fluid port, B1 hydraulic fluid port respectively, and A1/B1 hydraulic fluid port is and on output shaft, processes mutual noninterference oil duct and be communicated with, as shown in Figure 4, A1/B1 hydraulic fluid port is communicated with housing A/B hydraulic fluid port, realizes the fixture fuel feeding of driven member, fuel feeding process can be from the working oil of motor simultaneously or when different, according to work object, determine, according to more complicated synchronous fuel feeding, it is example, motor operations oil as mentioned above, just realize and being rotated counterclockwise, drive driven member to be synchronously rotated counterclockwise, the fixture of driven member also synchronously rotates, now the fixture of driven member is assumed to be oil cylinder, as routine wish work, now oil circuit is that oil cylinder working oil enters motor inside by the A/B hydraulic fluid port on housing, oil duct in output shaft flows out from A1/B1 hydraulic fluid port, enter the active chamber of oil cylinder, promote oil cylinder and produce stroke, the oil of inoperative oil pocket flows out and enters motor inside through B1/A1 hydraulic fluid port, by the oil duct of output shaft and the B/A hydraulic fluid port of housing, flow back to fuel tank, complete a working procedure of oil cylinder, at output shaft, when being connected, heart portion passage has circular groove, can realize the uninterrupted fuel feeding of 360 degree, better realized the highly difficult composite move that rotation limit, similar limit is firmly grasped or unclamped, and no longer occur around pipe and the limited problem of corner because producing around pipe, greatly increase work efficiency
