The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.

Shown in Fig. 1 ~ 5, the present invention is a kind of frame roller that can circumferentially regulate, comprise cover 2 in the roller, cover 2 is outside equipped with roller leather sheath 1 in the roller, in the cover 2 bearing 3 is installed in the roller, bearing 3 is sleeved in the rotating shaft 9, and an end of bearing 3 is provided with dust cap 8, and the other end of bearing 3 is fixing by rivet 4.Improvements of the present invention are to be provided with elastic ring 6 between bearing 3 and rotating shaft 9.

The mounting structure of elastic ring 6 can have multiple, below is specific embodiment:

Embodiment 1 has peripheral inner slot as shown in Figure 2 on the inner ring of bearing 3, the outer wall of elastic ring 6 is a tight fit in the inside groove, and the inwall of elastic ring 6 is a tight fit in the rotating shaft 9.Rotating shaft 9 and bearing 3 other parts are matched in clearance, thereby make rotating shaft 9 under the effect of elastic ring 6, in the interstice coverage of itself and bearing 3, realize regulatory function at circumferencial direction.Embodiment 1 need modify bearing 3 structures, adopts special bearing, generally is of little use.

Embodiment 2 as shown in Figure 3, Figure 4, tight fit has rotating shaft lining 5 in the inner ring of bearing 3, rotating shaft lining 5 matched in clearance are in rotating shaft 9, by jump ring 7 axial location.Have peripheral inner slot on the inwall of rotating shaft lining 5, the outer wall of elastic ring 6 is a tight fit in the inside groove, and the inwall of elastic ring 6 is a tight fit in the rotating shaft 9.Rotating shaft 9 and rotating shaft lining 5 other parts are matched in clearance, thereby make rotating shaft 9 under the effect of elastic ring 6, in the interstice coverage of itself and rotating shaft lining 5, realize regulatory function at circumferencial direction.Embodiment 2 can adopt plain bearing.

Embodiment 3 is combined with rotating shaft lining 5 at the inner ring internal clearance of bearing 3 as shown in Figure 5, and rotating shaft lining 5 is a tight fit in the rotating shaft 9,, by jump ring 7 axial location.Have circumferential water jacket on the outer wall of rotating shaft lining 5, the inwall of elastic ring 6 is a tight fit in the water jacket, and the outer wall of elastic ring 6 is a tight fit in the inner ring of bearing 3.Rotating shaft lining 5 and bearing 3 other parts matched in clearance, thus make rotating shaft 9 and rotating shaft lining 5 under the effect of elastic ring 6, in the interstice coverage of itself and bearing 3, realize regulatory function at circumferencial direction.

Embodiment 4 as shown in Figure 6, tight fit has bearing inner sleeve 10 in the inner ring of bearing 3, rotating shaft 9 tightens and is combined with rotating shaft lining 5, by jump ring 7 axial location.Rotating shaft lining 5 matched in clearance have peripheral inner slot on the inwall of bearing inner sleeve 10 in bearing inner sleeve 10, the outer wall of elastic ring 6 is a tight fit in the inside groove, and the inwall of elastic ring 6 is a tight fit on the rotating shaft lining 5.Thereby make rotating shaft 9 and rotating shaft lining 5 under the effect of elastic ring 6, in the interstice coverage of itself and bearing inner sleeve 10, realize regulatory function at circumferencial direction.

Rotating shaft lining 5 among the present invention can connect by tongue and groove between the two halves in the axial direction in two.This structure is convenient to install.

Rotating shaft lining 5 among the present invention and bearing inner sleeve 10 can adopt metal to make, and also can adopt plastics to make.

The present invention is at roller rotating shaft 9(or rotating shaft lining 5) and bearing 3(or bearing inner sleeve 10) between adopt elastic ring 6, utilize the elasticity of elastic ring 6 to realize circumferential regulatory function, prevent between roller parts and board rotating shaft owing to beating and moving labile state appears in excesssive gap, guarantee frame realization long-time steady operation state, prolong roller service life, reduce the frame maintenance cost.
