Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Fig. 1 ~ 5, the present embodiment provides a kind of voussoir centrifugal free wheel device, comprise outer shroud 1 and inner ring 2, inner ring 2 is arranged in outer shroud 1, forms raceway between outer shroud 1 and inner ring 2, is provided with wedging assembly in raceway, wedging assembly is outside equipped with extrusion pressing type sealing 3, both sides outside extrusion pressing type sealing 3 are respectively arranged with hole gear 4 and axle bumper 5, and hole gear 4 fixes in outer shroud 1, and axle bumper 5 fixes on the excircle of inner ring 2.Outer shroud 1 and inner ring 2 are hollow cylinder, and structure is simple, and favourable processing, can be processed into the aperture of various sizes as requested, precision easily controls.Extrusion pressing type sealing 3, structure is simple, and convenient disassembly, not only in order to seal, also replace the effect of end cap, the reduction that takes up space, cost is low.
The centrifugal free wheel device of voussoir also comprises stop pin 6, and one end of stop pin 6 fixes on the shelves of hole, is connected by wedging assembly by stop pin 6 with outer shroud 1.
Wedging assembly comprises voussoir 7, roller 8, yoke plate 9, pillar 11 and sunk screw 10, yoke plate 9 is two, be disposed in parallel between outer shroud 1 and inner ring 2, two yoke plates 9 are fixed by pillar 11 and sunk screw 10, voussoir 7 and roller 8 by the little axle of the cylinder at two ends respectively plug-in mounting enter in the corresponding axis hole of two yoke plates 9, and freely can to rotate in two yoke plate 9 axis holes.Roller 8 is for supporting and location.
Voussoir 7 both sides are small arc-shaped radius and the wear-resisting curved working face through cure process of decentraction large eccentricity distance, and two wear-resisting curved working faces contact with the external diameter of inner ring 2, the internal diameter of outer shroud 1 respectively.Voussoir 7 is designed to large eccentricity distance, the circular arc working surface of small arc-shaped radius, and suffered stress is little, the life-span is long, and implements vapor deposition, improves surface hardness and increases wear-resisting property.
As the utility model preferably technological scheme, the quantity of roller 8 is at least 3, is evenly distributed in raceway, and voussoir 7 quantity between adjacent two rollers 8 is at least 1.
As the utility model preferably technological scheme, wedging assembly also comprises the helical spring 12 that head and the tail connect into ring, half tangent plane along voussoir 7 two ends of inner ring 2 outside diameter is placed, swollen outside circumferencial direction, voussoir 7 being kept strokes, for ensureing that voussoir 7 contacts with outer shroud 1, providing initial frictional, and keep being in separated state with inner ring 2, ensure that voussoir 7 is kept strokes.According to different wedging rotating speeds, the parameter of different helical springs 12 can be selected.
Working principle:
Working principle of the present utility model and conventional free wheel device are distinguishing.
Conventional free wheel device decides " being separated (disengagement) " and " combining (wedging) " with inside and outside ring 1 slip, the centrifugal free wheel device of the utility model voussoir is then decide " being separated (disengagement) " and " combining (wedging) " of outer shroud 1 and inner ring 2 with the rotating speed of outer shroud 1 height, when host-initiated just starts, when driving outer shroud 1 to rotate along (inverse) hour hands to be less than a certain slow-speed of revolution, also wedging assembly and roller 8 is driven to rotate together, and inner ring 2 is under the obstruction of load resistance, although exist force of rolling friction still can not with outer shroud 1, roller 8 run-in synchronism.Under the effect of spring expansive force, make voussoir 7 and inner and outer rings 1 raceway be in contactless state, namely " separated state " can be considered that the slow-speed of revolution " surmounts ", inner ring 2 dally not with outer shroud 1 run-in synchronism.Voussoir 7 drives one piece of rotation by outer shroud 1, and therefore, certainly will will produce centrifugal force, and centrifugal force just produces a torque to voussoir 7 supporting point, its direction is contrary with the torque that helical spring 12 is applied to voussoir 7.This torque makes voussoir 7 transfer by separated state the trend of contact with inner ring 2 to, and voussoir 7 centrifugal force increases rapidly with the raising of rotating speed.The centrifugal force produced because of voussoir when main frame just starts 7 is not enough to overcome the torque that helical spring 12 is applied to voussoir 7, makes voussoir 7 and inner ring 2 be in separated state, because voussoir 7 centrifugal force increases along with the raising of outer shroud 1 rotating speed.When rotating speed improve meet or exceed this clutch a certain contact speed range time, centrifugal force torque and being increased to overcomes helical spring 12 when being applied to the torque of voussoir 7, voussoir 7 is forced to deflect like this and after eliminating Separation, in outer shroud 1, raceway drives voussoir 7 to enter and forces wedging state, and a year driving is formed to inner ring 2, clutch is in bonding state, and at this moment outer shroud 1 drives inner ring 2 synchronous operation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
