Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of contactless free wheel device, by the improvement of voussoir sectional shape and structure, solve existing eccentric installation and do not turn over that block contactless free wheel device voussoir axle small in ends is easily broken, the problem of clamping stagnation, there is reasonable in design, manufacturing process is simple, large, the eccentric strong adaptability of reliable operation, bearing torque, does not turn over the feature of block, long service life.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of contactless free wheel device, comprise inner ring 2 and outer shroud 1, a pair maintenance circle 3 is provided with between inner ring 2 and outer shroud 1, linked together by pin 8 between a pair maintenance circle 3, described maintenance circle 3 is provided with at least one pair of symmetrical positioning block 4, between the positioning block 4 of symmetry, be provided with voussoir 5, described voussoir 5 is provided with torsion spring 6, make voussoir 5 and inner ring 2, outer shroud 1 close contact.
Described maintenance circle 3 is fixed in inner ring 2 by circlip for shaft 7.
Described voussoir 5 is provided with working surface and lower working surface, the right side recess of upper and lower working surface is provided with protruding locating face one, the left side of upper and lower working surface is provided with locating face two and locating face three, locating face two is near upper working surface, locating face three is near lower working surface, and the radius of described locating face three is greater than the radius of lower working surface.
Described locating face two is the round and smooth setting of evagination with locating face three, and described locating face one is the setting that caves inward, and it is protruding that recess inside is provided with a bit of circular arc.
Described positioning block 4 is provided with the die cavity corresponding with voussoir 5 locating face, and the two ends of described voussoir 5 are inserted into the die cavity of positioning block 4.
The beneficial effects of the utility model:
The utility model provides a kind of and improves voussoir centering mode, reasonable in design, and manufacturing process is simple, large, the eccentric strong adaptability of reliable operation, bearing torque, do not turn over block, non-contact clutch that long service life suitable batch is produced.Its principle is: improved by voussoir 5 cross section, make its have eccentric installation and do not turn over block function prerequisite under, add three sections of locating faces, circle 3 is kept to be provided with the positioning block 4 with locating mould cavity, voussoir 5 two ends are inserted in positioning block 4 die cavity, form three sections of circular arc adjective-centre structures, therefore voussoir 5 is without the need to processing the little axle at two ends, drawing, surface trimming once-through can be adopted, positioning block 4 can adopt precision casting, stick with glue knot with maintenance circle 3, manufacturing efficiency greatly promotes, and is applicable to producing in enormous quantities.
The utility model novel structure, technique is simple, reliable performance, safeguards simple, failure rate is low.The utility model is while performance improves, and by process modification, reduce cost of production, product cost is high.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 3: a kind of contactless free wheel device, comprise inner ring 2 and outer shroud 1, a pair maintenance circle 3 is provided with between inner ring 2 and outer shroud 1, linked together by pin 8 between a pair maintenance circle 3, described maintenance circle 3 is provided with at least one pair of symmetrical positioning block 4, between the positioning block 4 of symmetry, be provided with voussoir 5, described voussoir 5 is supporting is provided with torsion spring 6, makes voussoir 5 and inner ring 2 outer shroud 1 close contact.
Described maintenance circle 3 is fixed in inner ring 2 by circlip for shaft 7.
As shown in Figure 1: described voussoir 5 is provided with working surface and lower working surface, the right side recess of upper and lower working surface is provided with protruding locating face one, the left side of upper and lower working surface is provided with locating face two and locating face three, locating face two is near upper working surface, locating face three does face on lower, and the radius of described locating face three is greater than the radius of lower working surface.
Described locating face two is the round and smooth setting of evagination with locating face three, and described locating face one is the setting that caves inward, and it is protruding that recess inside is provided with a bit of circular arc.
As shown in Figure 3: described positioning block 4 is provided with the die cavity corresponding with voussoir 5 locating face, the two ends of described voussoir 5 are inserted into the die cavity of positioning block 4.
Working principle of the present utility model is:
As shown in Figure 4: when inner ring 2 along arrow indicate surmount direction rotate time, the utility model is in and surmounts state, when inner ring 2 high speed rotating, the voussoir 4 on it, due to centrifugal action, overcomes the constraint of torsion spring 6 and inner ring 2 outer shroud 1 and departs from and realize non-contact and operate.When inner ring 2 against arrow indicate surmount direction rotate time, more wedge is tighter in inner ring 2, outer shroud 1 gap for voussoir 5, and the utility model is in torsion pass state.
As shown in Figure 4: when inner ring 2 produces bias with outer shroud 1 owing to installing, voussoir 5 of the present utility model around the center of rotation determined by three locating faces by self pose adjustment, gap change between inner ring 2 outer shroud 1 that the eccentric E of automatic adaptation causes, normal realization surmounts and torsion pass function.
When the utility model torsion pass also produces overload, voussoir 5 is around center of rotation, height point towards upper working surface rotates, when rotation reaches the intersection point of lower working surface and locating face three, because lower locating face three radius is greater than lower working surface, loading angle between voussoir 5 and inner ring 2 becomes suddenly large, stops voussoir 5 to continue to rotate along center of rotation, realizes not turning over block function.
The maximum feature of the utility model is: adapt to eccentric installation, do not turn over block, shock-resistant, safeguard simple, and by improving voussoir 5 and keeping circle 3 and positioning block 4 processing technology, significantly reduce difficulty of processing, be applicable to very much producing in enormous quantities.
