Embodiment
Clearer for technical problem, technological scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figures 1 to 4, the utility model embodiment's compensation cladding type rotary shaft mainly comprises support 1, public axle 2, female axle 3, fixing frame 4, can be provided with oil storage tank in public axle 2 and female axle 3 contact position, and coating lubricant fat improves contact friction.
Have an attachment hole 101 and at least one mounting hole 102 on the support 1.By attachment hole 101, the linkage section 2104 of support 1 and axostylus axostyle 21 is fastenedly connected and is integral; By mounting hole 102, support 1 is fixedlyed connected with first object (as notebook computer upper cover).
Lamellar body 22 is the thin slice body structure of cross section for the fan ring, and the thickness of lamellar body 22 is not less than the height of positioning pawl 2101 projectioies.Lamellar body 22 comprises outer surface 2201, internal surface 2202, bi-side 2203, first end face 2204 and second end face 2205.Outer surface 2201 will with the axle sleeve 31 inner peripheries 3102 tight contact matching of female axle 3, frictional rotation relatively between the two; Internal surface 2202 closely contacts with mast 2102 surfaces 2106 of axostylus axostyle 21; Bi-side 2203 closely contact with the positioning pawl 2101 of axostylus axostyle 21, realize the synchronous rotation of lamellar body 22 and axostylus axostyle 21; First end face 2204 contacts with the positioning table 2105 of axostylus axostyle 21, and the mast 2102 of axostylus axostyle 21 does not exceed second end face 2205, realizes the axially locating of lamellar body 22 and axostylus axostyle 21 jointly, guarantees that both can slide relative when rotating shaft is worked.
