Abstract
The utility model provides a special shaped structure pivot includes bearing and runner, there is a round hole in runner center department, the round hole department at the runner is installed to the bearing, the rim surface of runner is " W " form recess, " W " form recess surface hot melt has copper base powder metallurgy layer. Technical scheme's beneficial effect lies in: designed a pivot that is exclusively used in rope or cable wire conversion atress orientation, through there being copper base powder metallurgy layer at rim surface hot melt, the effectual frictional force that has strengthened between rope or cable wire and the pivot is applicable to the drawknot of great effort.
Description
Technical field
The utility model relates to precision optical machinery field, particularly relates to a kind of polymorphic structure rotating shaft.
Background technique
Bearing (Bearing) be that link product zero main part must be used, for not only having born moment of flexure in rotation work but also having born the axle of moment of torsion.
During some Machine Design, need to use the rotating shaft with large frictional force, particularly rope or rope driven rotating shaft, existing rotating shaft surface is all comparatively smooth, cannot meet some special requirement transmissions.In addition, existing turning shaft structure is more common, does not also have special design proposal for the rotating shaft by rope or cable wire conversion Impact direction.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind of rotating shaft of polymorphic structure, and described rotating shaft has that structure is simple, frictional force is large, low cost of manufacture, and meets mechanical field particular design needs.
A kind of polymorphic structure rotating shaft described in the utility model comprises bearing and runner, and there is a circular hole at described roller centre place, and described bearing is arranged on the circular hole place of runner; The rim surface of described runner is " W " shape groove, and described " W " shape groove surfaces hot melt has copper-base powder metallurgy layer.
Further, described circular hole is also provided with a groove, described bearing surface is provided with a projective structure matched with circular hole groove size.
The beneficial effect of technological scheme described in the utility model is: have devised a kind of rotating shaft being exclusively used in rope or cable wire conversion Impact direction, by having copper-base powder metallurgy layer at rim surface hot melt, effectively increase rope or the frictional force between cable wire and rotating shaft, be applicable to the drawknot compared with noticeable effort.
Accompanying drawing explanation
A kind of polymorphic structure rotating shaft of Fig. 1 overall structure schematic diagram;
The axle centre structure schematic diagram of a kind of polymorphic structure rotating shaft of Fig. 2.
In figure: 1 bearing, 2 runners, 3 " W " shape groove, 4 copper-base powder metallurgy layers, 5 grooves, 6 circular holes, 7 wheel rims.
Embodiment
As depicted in figs. 1 and 2, a kind of polymorphic structure rotating shaft of the present invention comprises bearing 1 and runner 2, and there is a circular hole 6 center of described runner 2, and described bearing 1 is arranged on circular hole 6 place of runner 2; Wheel rim 7 surface of described runner 2 is " W " shape groove 3, and the surperficial hot melt of described " W " shape groove 3 has copper-base powder metallurgy layer 4.Described circular hole 6 is also provided with a groove 5, described bearing 1 surface is provided with a projective structure matched with circular hole groove 5 size.
Claims (2)
1. a polymorphic structure rotating shaft, is characterized in that, described rotating shaft comprises bearing and runner, and there is a circular hole at described roller centre place, and described bearing is arranged on the circular hole place of runner; The rim surface of described runner is " W " shape groove, and described " W " shape groove surfaces hot melt has copper-base powder metallurgy layer.
2. a kind of polymorphic structure rotating shaft as claimed in claim 1, is characterized in that, described circular hole is also provided with a groove, and described bearing surface is provided with a projective structure matched with circular hole groove size.
