Abstract
The utility model relates to a double cage over-running clutch, comprising an internal cage(3), an external cage(2), a wave spring (4), a wedge(1), an arc protruding stage for positioning along the direction of axis is arranged on lintels of an inward radial hole of an internal cage and an outward radial hole of an external cage. Internal (3) and external (2) cages are of plastics of engineering. The model can reduce the working quantity of mechanical processing, decrease cost of production and is of small centrifugal force, good vibration absorbing, good toughness, impact resistance, easy assembly and disassembly.
Description
Technical field
The utility model relates to technical field of bearings, specifically, is a kind of novel pair of retainer free wheel device.
Background technique
The reliability height that Wedge type over running clutch had, usability is good, long service life, carrying torque are big, advantages such as boundary dimension compactness are widely used in fields such as aircraft, tank, military trucks, automobile, loader, printing machinery, textile manufacturing machine, mining machinery.
Such as previously disclosed 03102580.3,03237184.5,00240600.4 etc. disclosed pair of retainer voussoir free wheel device, all traditional mono-directional overrun clutch has been done improvement in various degree, generally by flanged inside and outside retainer, inside and outside centering card, wave mode spring and voussoir are formed.The wave mode spring is between inside and outside retainer, and among the fenestra of the uniform and inside and outside retainer wavy spring of voussoir, the installation of two retainer free wheel devicees is with inside and outside centering fastening position.Inside and outside retainer and inside and outside centering card are to adopt the metal material drawing, because the design of part complexity, quantity is many, and the operation that manufacture process relates to is more, the cost of production height, and also the stressed back of inside and outside retainer easily produces permanent deformation.
The model utility content
In order to solve the problem of above-mentioned existence, the utility model provides a kind of novel pair of retainer free wheel device, can reduce production costs.And centrifugal force is little, and slow shaking property is good, and good toughness is shock-resistant, easily assembling, dismounting.
The utility model is to adopt following technological scheme to realize: described novel pair of retainer free wheel device, comprise interior retainer, outer retainer, wavy spring, voussoir, voussoir is packed among interior retainer internal diameter fenestra and wavy spring fenestra and the outer retainer external diameter fenestra, interior retainer internal diameter fenestra lintel is provided with setting circle arc boss vertically, and outer retainer external diameter fenestra lintel is provided with setting circle arc boss vertically.The material of retainer and outer retainer is engineering plastics in being somebody's turn to do, and single injection-molded.
The obtained effect of the utility model is as follows: the utility model volume is little, compact structure, meshing performance are reliable, and its inside and outside retainer adopts engineering plastics material, utilizes the injection moulding one-shot forming technique, reduces mach workload, reduces production costs.And centrifugal force is little, and slow shaking property is good, and good toughness is shock-resistant, easily assembling, dismounting.

Embodiment
As shown in Fig. 1,2,3,4,5,6, retainer 3, outer retainer 2, wavy spring 4, voussoir 1 in novel pair of retainer free wheel device comprises, in the outer retainer 2 wavy spring 4 is housed, retainer 3 in being equipped with in the wavy spring 4, voussoir 1 are enclosed among interior retainer 3 internal diameter fenestras and wavy spring 4 fenestras and the outer retainer 2 external diameter fenestras; Outer retainer 2 external diameter fenestra lintels are provided with setting circle arc boss vertically; Interior retainer 3 internal diameter fenestra lintels are provided with setting circle arc boss vertically; Inside and outside retainer positioning boss has played the radial location effect of installing and using.
Wavy spring 4 is installed between interior retainer 3, the outer retainer 2, several voussoirs 1 are uniformly distributed among the fenestra of interior retainer 3, outer retainer 2, wavy spring 4, rely on the effect of wavy spring 4 that voussoir 1 is in and inside and outside raceway even contact state, boss on outer retainer 2 external diameters makes outer retainer 2 be in interference with outer raceway and contacts, and guarantees the radial location that clutch is good; The boss and the interior raceway of interior retainer 3 internal diameters have certain clearance, retainer 3 in guiding.
Inside and outside retainer 3,2 of the present utility model all adopts the engineering plastics material, utilizes the injection moulding one-shot forming technique, reduces mach workload, reduces production costs.
Voussoir 1 is packed between the outer ring and inner ring of bearing, under the effect of wavy spring 4, voussoir 1 is in and the interior raceway of outer ring and the outer raceway even contact state of inner ring.
When the outer ring is a circle initiatively, inner ring is during by moving-coil, and the outer ring rotates counterclockwise, preceding overcoming the elastic force of wavy spring 4 by the long-diagonal of rhombus voussoir 1, short diagonal after, less than the distance between the Internal and external cycle, the outer ring drives voussoir 1 and slides, and inner ring is in the state of leaving.If the outer ring clockwise rotates, the short diagonal of rhombus voussoir 1 is preceding, long-diagonal after, under the effect of wavy spring 4, outer ring drive voussoir 1 long-diagonal (greater than the distance between the Internal and external cycle) cambered surface is moved forward compress inner ring, this moment, Internal and external cycle was integrated, and then inner ring clockwise rotates.
When inner ring is a circle initiatively, the outer ring be during by moving-coil, principle equally, and inner ring clockwise rotates, and Internal and external cycle is in disengaged position.If inner ring rotates counterclockwise, Internal and external cycle is in closed state, and then the outer ring is driven also and rotates counterclockwise.
Claims (2)
1, a kind of novel pair of retainer free wheel device, comprise interior retainer (3), outer retainer (2), wavy spring (4), voussoir (1), voussoir (1) is packed among interior retainer (3) internal diameter fenestra and wavy spring (4) fenestra and outer retainer (2) the external diameter fenestra, it is characterized in that: retainer (3) internal diameter fenestra lintel is provided with setting circle arc boss vertically in described, and outer retainer (2) external diameter fenestra lintel is provided with setting circle arc boss vertically.
