Embodiment

See also Fig. 1 its implementation process is described: speed stabilization machine, comprise axle 11, outer tube 1, axle 11 is positioned at outer tube 1, and outside the axle 11 1 end protruded tubes, pipe 3 in the other end that joins with axle 11 in the outer tube 1 is provided with, axle 11 is provided with oil sac 8 near an end overcoat of interior pipe 3, and oil sac 8 is the bag shape of an annular, and the opening end of oil sac 8 is arranged on interior pipe 3 and the axle 11, be provided with piston 4 between axle 11 and the interior pipe 3, there is a center hole 2 at the center of axle 11.Jump ring groove 13 is arranged outside the outer tube 1, round copper packing 18 is arranged outside the axle 11.

Be with collar 19 in the oil sac 8, oil sac 8 communicates with interior pipe 3 inner cavities by oil through 25, be connected with piston check valve 20 between axle 11 and interior pipe 3 inner cavities, piston check valve 20 has pagoda spring 23 near the side top of interior pipe 3 inner cavities, the end of pagoda spring 23 withstands jump ring 22, and pagoda spring 23 has piston only 24.Be provided with O shape circle 26 between piston 4 and the interior pipe 3, be provided with spacer 7 and the 2nd O shape circle 21 between axle 11 and the outer tube 1, outer tube 1 inner axis of heart 11 outer protecgulum 10, spring 9, the spring seats 12 of being with successively, spring 9 two ends withstand on respectively between protecgulum 10 and the spring seat 12, be respectively arranged with dust ring 16 and composite bearing 14 between protecgulum 10 and the axle 11, be provided with second jump ring, 17, the three O shapes circle 15 between protecgulum 10 and the outer tube 1.The other end adjustment seat 6 of phase center rollers 11 in the interior pipe 3, adjustment seat 6 axially is provided with through hole, and through hole is outside equipped with filter screen 34, be provided with oil-draining locknut 32 in adjustment seat 6 axial holes corresponding with filter screen 34, adjustment seat 6 sidewalls are provided with valve line 28 and draw-in groove 30, be provided with the 4th O shape circle 29 between adjustment seat 6 and the outer tube 1, in pipe 3 and valve line 28 in alignment be provided with metering orifice 27, outer tube 1 one end oil-draining locknuts 32 are externally connected with regulation cock 33, and regulation cock 33 is horizontally arranged with top screw 31; The material of described piston 4 is a stainless iron, and the wear-resisting guide pin bushing of tetrafluoroethylene is arranged in the piston 4.During work: pneumatic hydraulic promotes axle 11 motions, and check valve 20 is opened or closed, thus 5 compressions of the hydraulic oil in the pipe 3 or expansion in the promotion.Because the effect of oil sac 8 is arranged, hydraulic oil 28 can only move in oil sac, can not leak.Can leakage of oil, so it is abrasion resistance is more, more firm.
