Detailed description of the invention
Embodiment 1
See Fig. 1-Fig. 8, a kind of fluid-power motor, include housing 1, it is arranged at the drive shaft 2 within housing 1, two are arranged at that housing 1 is internal and symmetry is fixedly connected on the rotary oscillation arm 3 on drive shaft 2 outer wall, it is positioned at the liquid feed device exocoel 4 of drive shaft 2 outer ring, liquid feed device inner chamber 5 between drive shaft 2 and liquid feed device exocoel 4, ring-shaped liquid chamber 6 between liquid feed device exocoel 4 and housing 1, the isolation support arm 7 that three are arranged within ring-shaped liquid chamber 6, it is arranged at the liquid feed device base 8 bottom housing 1, it is arranged at the inlet 9 bottom liquid feed device base 8 and liquid outlet 10；The outer end of two rotary oscillation arms sequentially passes through liquid feed device inner chamber 5 and liquid feed device exocoel 4 and fits with housing 1 inwall；Two inlet openings 41 connected with ring-shaped liquid chamber 6 it are provided with on liquid feed device exocoel 4, it is provided with two liquid outlets 51 connected with ring-shaped liquid chamber 6 on liquid feed device inner chamber 5, and each inlet opening 41 and each liquid outlet 51 lay respectively at the both sides of each rotary oscillation arm；Isolation support arm 7 is adjustable end stop structure, the inner outer wall laminating with liquid feed device exocoel 4, fits with housing 1 inwall in outer end, and the end face of both sides is oblique section, top end face is arc surface, and bottom is provided with spring card slot 71, and return spring 72 is placed in spring card slot 71；Liquid feed device base 8 is made up of the feed flow base internal ring 81 connected with liquid outlet 10 and the feed flow base outer shroud 82 connected with inlet 9.
The operation principle of fluid-power motor:
Seeing Fig. 1, rotary oscillation arm 3 consistently forms an anticlockwise revolving force in ring-shaped liquid chamber 6: the liquid on the left of rotary oscillation arm 3 is flowed outwardly by liquid outlet 51, and the liquid on the right side of rotary oscillation arm 3 is flowed inward into by inlet opening 41；The liquid flowed out on the left of rotary oscillation arm 3 provides a thrust counterclockwise for rotary oscillation arm 3, and the liquid flowed on the right side of rotary oscillation arm 3 provides a suction counterclockwise for rotary oscillation arm 3；Effect backspin switch swing arm 3 at two active forces forms an anticlockwise revolving force, makes rotary oscillation arm 3 rotate counterclockwise.
Seeing Fig. 3-Fig. 5, isolation support arm 7 is adjustable end stop structure, is not the effect by return spring 72 by free state during external force, makes isolation support arm 7 all extend and split ring-shaped liquid chamber 5；When rotary oscillation arm 3 is by isolation support arm 7, isolation support arm 7 pressurized compresses downwards motion, now return spring 72 compress energy storage, when rotary oscillation arm 3 arrives the top of isolation support arm 7, isolation support arm 7 bottoms out, ring-shaped liquid chamber 6 is in complete channel status so that rotary oscillation arm 3 can pass through;When rotary oscillation arm 3 is completely by isolation support arm 7, isolation support arm 7 is released back into entirely isolating cutting state by full-gear again by the compress energy storage of return spring 72.
Based on said structure principle, thus achieve the anticlockwise rotation continuous, smooth in annular housing 6 of the effect backspin switch swing arm 3 at outside hydraulic power.
Seeing that Fig. 9 and Figure 10, rotary oscillation arm 3 are one, isolation support arm 7 is two, and other structures are with embodiment 1, and operation principle is with embodiment 1.
