master are convex 801 contact of wheel, therefore, when compound cam mechanism 8 rotates, surface scrolls of the idler wheel 1407 along main cam 801, outer ball 1406 Along 803 surface scrolls of cam ring 802 and external cam, to form supported at three point, the reliability and stationarity of movement are improved, in bullet Under spring 1408 and 801 collective effect of main cam, the piston 1402 being connected with guide rod 1403 is done back and forth in fan-shaped cylinder body 1401 Linear motion, so that cooling water is entered cylinder body through water suction check valve 1410, connecting tube 1409, then continuously through water delivery baffle ring 1411 And apopore 1412 is pumped into the cavity between inner housing 12 and outer housing 13, is most discharged into tube body 16 through outlet pipe 15 afterwards, in order to mention The uniformity that high coolant liquid is distributed between inner housing 12 and outer housing 13, servo-actuating device 24 work, drive and pressure The connected push rod 20 of sensor 22 moves up, to change the compression degree of the first spring 21, prevent coolant liquid will be from easily will Seal head 19 and throttle seat 18 are detached from, so that coolant liquid can reach between inner housing 12 and outer housing 13 cavity arbitrarily Side effectively improves the utilization rate of coolant liquid, and then improves heat dissipation effect.A part of coolant liquid that pumping means 14 generates when working Enter in cooling annular groove 25 through coolant liquid feed liquor check valve 2701, coolant liquid inlet pipe 27 and exchanged with the progress heat of cooling fins 26, To cool down to seal head 19 and tube body 16, then, which enters soaking device 29 through coolant liquid outlet pipe 28, by In through tube body 16 enter branch pipe 1601 thermal medium after 2903 water conservancy diversion of flow guiding head, fluid state by turbulence transition be laminar flow, with The cold medium for being set the outflow of fluid hole 2905 on the equal liquid head 2904 of taper, which can be carried out, to be sufficiently mixed, to reduce thermal medium Temperature, effectively improve the comprehensive utilization ratio of cold medium.The apparatus structure is simple, using water-cooling pattern, not only good cooling results, And it is not necessary that pump and its control system, and stable drive, good reliability is in addition separately provided, cooling capacity is with first rotating shaft 2 Revolving speed is increased and is improved, meanwhile, fluid pressure is adjustable, has both been able to satisfy low-load starting and has required, also can coolant liquid reached Cavity anywhere, to improve the utilization rate of coolant liquid, and then improves cooling effect between inner housing 12 and outer housing 13.

The utility model is not limited to above-mentioned specific embodiment, and those skilled in the art visualize from above-mentioned Hair, without creative labor, the various transformation made are all fallen within the protection scope of the utility model.
