Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the main body of face contact type free wheel device of the present invention is driving shaft 1, be with interior ring member on this driving shaft 1, ring member is provided with outer shroud 2 outward in it, outer shroud 2 two ends are respectively equipped with end cap 3, ring member comprises left retainer 41 in described, right retainer 42, described left retainer 41, evenly establish several special-shaped voussoirs 5 between the right retainer 42 and around described driving shaft 1, present embodiment adopts four special-shaped voussoirs 5, described special-shaped voussoir 5 is the outer arced surface sector unit, the outer arced surface of this sector unit contacts with the aperture surface cooperation of described outer shroud 2, the center of each special-shaped voussoir 5 is all by eccentric wheel and eccentric shaft 51 and left retainer 41, right retainer 42 connects, one end of described eccentric shaft 51 stretches out left retainer 41 and at the fixedly connected tooth sector 6 of eccentric shaft 51 these ends, tooth sector 6 and special-shaped voussoir 5 corresponding cooperations, so present embodiment tooth sector 6 also evenly distributes four around driving shaft 1, fixedly connected driving gear 7 on driving shaft 1, this driving gear 7 is meshed with tooth sector 6, at described left retainer 41, set position bolt 43 between the right retainer 42, head one end of this holding down bolt 43 is positioned at a side of tooth sector 6.Be provided with certain distance between left retainer 41 of the present invention, the right retainer 42 and by holding down bolt 43 the two joined together, this distance is enough to make special-shaped voussoir 5 to move radially.
Special-shaped voussoir 5 of the present invention is the outer arced surface sector unit, and the fan-shaped cambered surface of this abnormity voussoir 5 contacts with outer shroud 2 cooperations.Launching special-shaped voussoir 5 is to have endoporus and engage sleeves to be contained on the eccentric wheel, and the two ends of eccentric shaft 51 penetrate in the hole of left retainer 41, right retainer 42, and can rotate.Driving shaft 1 and driving gear 7 rotate, and are transmitted in tooth sector 6, make tooth sector 6 compress special-shaped voussoir 5 in outer shroud 2 inwalls, thus driving shaft 1 and interior ring member and outer shroud 2 unitary rotation.The present invention just can realize the effect of free wheel device like this, and not easy to wear, bearing capacity is high, wedging is reliable, it is almost nil to open resistance.
The endoporus running in bearings of two end caps 3 of the present invention, and be sleeved on the driving shaft 1, be used for support outer shroud 2 in outer shroud 2 two ends, limit and retrain the radial position of outer shroud 2 and interior ring member and driving shaft 1, and the driving gear 7 on the interior ring member of sealing and the driving shaft 1.
Hence one can see that, when the counterclockwise reversed turning of driving shaft 1, tooth sector 6 rotates the disengaging that contacts that makes special-shaped voussoir 5 and outer shroud 2, namely so-called unlatching or title are separated wedge or are claimed and separate, and outer shroud 2 can continue the clockwise direction rotation, be that what is called surmounts, when outer shroud 2 rotating speeds rotate greater than driving shaft 1, also do and surmount state.
Ring member and driving shaft 1 can relatively rotate in need to prove, but amount of exercise is very little.
Another kind of technological scheme of the present invention, as Fig. 4, shown in Figure 5, the main body of face contact type free wheel device is driven shaft 11, be with interior ring member on this driven shaft 11, ring member is provided with outer shroud 2 outward in it, outer shroud 2 one ends are established left end cap 31, the other end is established right end cap 32, fixedly connected driving gear 7 on the described left end cap 31, ring member comprises left retainer 41 in described, right retainer 42, described left retainer 41, evenly establish several special-shaped voussoirs 5 between the right retainer 42 and around described driven shaft 11, present embodiment adopts four special-shaped voussoirs 5, described special-shaped voussoir 5 is the sector unit of intrados, fixedly connected circular wheel 8 on described driven shaft 11, the intrados of described sector unit contacts with described circular wheel 8 cooperations, described each special-shaped voussoir 5 center are all by eccentric wheel and eccentric shaft 51 and left retainer 41, right retainer 42 connects, one end of described eccentric shaft 51 stretches out left retainer 41 and is provided with tooth sector 6 at eccentric shaft 51 these ends, described tooth sector 6 is meshed with driving gear 7, at described left retainer 41, set position bolt 43 between the right retainer 42, one end of these holding down bolt 43 heads is positioned at tooth sector 6 one sides, left retainer 41 of the present invention, keep certain distance between the right retainer 42 and by holding down bolt 43 the two is joined together, this distance is enough to make special-shaped voussoir 5 to move radially.
This kind mode of execution is that the cambered surface of the special-shaped voussoir 5 on the described interior ring member of change is interior radially cambered surface.In the fixing circular wheel 8 of driven shaft 11, fixedly circular wheel 8 contacts with special-shaped voussoir 5 cambered surfaces cooperation in the middle of left retainer 41, right retainer 42, driving gear 7 fixing on the left end cap 31 meshes with tooth sector 6, when outer shroud 2 and left end cap 31 active rotation, driving gear 7 rotates, and driving gear 7 transmission tooth sector 6, special-shaped voussoir 5 compress circular wheel 8 and driven shaft 11 to the internal diameter direction displacement, namely so-called sealed, outer shroud 2 driving links and interior ring member, driven shaft 11 unitary rotation.When outer shroud 2 initiatively turns round or driven shaft 11 rotating speeds during greater than outer shroud 2 driving links, driven shaft 11 is for surmounting state.
In the technological scheme of the present invention, in order to make driving link keep suitably small gap at the surface of contact of revolution or the driven member time abnormity voussoir 5 that surmounts state and driven member, holding down bolt 43 can adopt the T-slot bolt, the head of this bolt is close to a side of tooth sector 6, play the spline positioning action, also can play a part to slow down and impact and the reduction vibration at shape rubber spring of the tight cover of T-slot bolt head.
