Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Damper like a kind of rotating speed adjustable of Fig. 1～shown in Figure 3; Mainly comprise one can fill damping oil axle sleeve 20, one can with the rotating shaft 10 that axle sleeve 20 cooperate through the seal ring sealed rotational and but the disturbance damping oil flows; Rotating shaft 10 ends are provided with a hexagon posts 11; Be embedded a nut 50 in the rotating shaft 10, hexagon posts 11 is provided with the circular hole 12 corresponding with nut 50; Be provided with at least one unidirectional fuel tap sheet 30 of crossing between rotating shaft 10 and the axle sleeve 20; Axle sleeve 20 1 ends are provided with one and can move axially to regulate the Sealing 40 of axle sleeve 20 inner chamber length; Sealing 40 is provided with the hex hole 41 of a hexagon posts 11 phase fits; And Sealing 40 is provided with the step hole 42 that communicates with hex hole 41, can place seal ring on the step hole 42; Sealing 40 is installed seal ring and is filled in the axle sleeve 10; Hexagon posts 11 in hex hole 41 on the Sealing 40 and the rotating shaft 10 is fit mutually; Make radially relative fixed of Sealing 40 and rotating shaft 10; Step hole 42 contrapositions on the circular hole in the rotating shaft 10 12 and the Sealing 40 simultaneously, packing ring of an adjusting screw 60 pads are passed step hole 42, circular hole 12 and are screwed with nut 50 and be connected, and Sealing 40 can be rotated with rotating shaft 10.Fill damping oil between rotating shaft 10, Sealing 40 and the axle sleeve 20.
Above-mentioned hexagon posts only is in order to limit Sealing diametrically, to make it to link with rotating shaft with cooperating of hex hole.Can also be employed in terminal other the non-circular Special-Shaped Column that adopt of rotating shaft 10, on Sealing, establish a special-shaped groove and Special-Shaped Column mutually activity plug together, all can reach similar effects.
Like Fig. 3 and shown in Figure 4, axle sleeve 20 inwalls are provided with one and are used for the hinged unidirectional boss 21 of crossing fuel tap sheet 30, and said Sealing 40 formed oil-gap 22 with the end face of boss 21.When needs regulate gap between Sealing 40 and the rotating shaft 10, when enlarging the storage space of rotating shaft 10 inner chamber damping oils simultaneously, backward rotation adjusting screw 60 makes the spacing increase of adjusting screw 60 terminations and nut; Can be Sealing 40 levels side shifting outside axle sleeve; Gap between increase Sealing 40 and the rotating shaft 10 enlarges the flow gap of damping oil to form oil-gap 22, makes when rotating shaft 10 is worked under damping state; The flow velocity of damping oil is accelerated; The damping force of damping oil countershaft 10 diminishes, and the rotational velocity of rotating shaft 10 accelerates, and then the time of rotating shaft 10 dampings rotation certain amplitude shortens.In the time of need making the damping rotation work of rotating shaft 10 rotating speed slack-off, when rotation time is elongated; Then be rotated in the forward adjusting screw 60; Make the gap smaller between Sealing 40 and the rotating shaft 10, until closing oil-gap 22, the mobile of damping oil slows down; It is big that the damping force of damping oil countershaft 10 becomes, and rotating shaft 10 is rotated slowly.
Above embodiment only supplies to explain the usefulness of the utility model; Non-restriction to the utility model; Those skilled in the art under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or variation; All technological schemes that are equal to also should belong to the utility model protection category, are limited each claim.
