Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
Shown in Fig. 1-9; one-way belt roller of automobile generator is made up of belt wheel hub 1 and the one-way clutch mechanism be located in it; one-way clutch mechanism comprises positive camber core wheel 2; two bearings 3; axle sleeve 4; eight rollers 5; article eight, flat spring 6; two bearing gasket sheets 7 and the two bobbins protection pad sheet 8 of accepting insurance; the outer wall of positive camber core wheel 2 is formed uniformly eight projectioies 12; the bi-side of projection 12 are respectively plane 10 and arc surface 11; with the right angle type transition, arc surface 11 and positive camber core are taken turns between 2 excircle with the transition of eccentric circle cambered surface between the excircle of plane 10 and positive camber core wheel 2.A fixedly connected flat spring 6 on each plane 10, the other end of flat spring 6 links to each other with roller 5 on being in the eccentric circle cambered surface.The central through bore of positive camber core wheel 2 is fixedlyed connected with generator shaft, and eight projection 12 outer ends of positive camber core wheel 2 are suit axle sleeve 4 rotationally, and the inwall of axle sleeve 4 outer walls and belt wheel hub 1 forces together.The two ends of the positive camber core wheel 2 roller pad 7 of packing into, roller pad 7 outsides reinstall bearing 3, and the outer side surface of bearing 3 is equipped with bearing protection pad 8.The outer wall of the inner ring of bearing 3 and positive camber core wheel 2 forces together, and the inwall of outer ring and belt wheel hub 1 forces together.
As shown in Figure 1, the outer side surface of positive camber core wheel 2 and bearing 3 is equipped with protective cover 9, and protective cover 9 can prevent the service behaviour of under the operating conditions dirt and the unidirectional mechanism of influence that dabbles, and guarantees unidirectional mechanism stable operation.Protective cover 9 snaps in after one-way belt roller is contained on the generator shaft, and belt wheel hub appearance is coated with one deck resin layer.
The present invention is installed in two kinds of fastening forms on the automobile generating arbor, employing internal tooth form shown in Figure 2 is fastening, and employing hexagonal shown in Figure 3 is fastening.
Working principle of the present invention is summarized as follows: during starting, utilize the tension force of flat spring 6 roller 5 to be pushed up the peak of the eccentric circle cambered surface 11 of positive camber core wheel 2, roller 5 contacts the inwall of axle sleeve 4, make the rotation in the same way synchronously of generator shaft, positive camber core wheel 2 and axle sleeve 4 and belt wheel hub 1, thereby belt wheel hub 1 can not be rotated in the opposite direction; When the rotating speed of belt wheel hub 1 slows down, generator shaft inertia rotating speed surpasses the rotating speed of belt wheel hub 1, at this moment, positive camber core wheel 2 can be carried back roller 5, flat spring 6 tension force are reclaimed, and roller 5 is got back to the minimum point of eccentric circle cambered surface 11, and the inwall of roller 5 and axle sleeve 4 is separated, thereby generator shaft can have inertia ground to rotate, and is not subjected to the influence of belt wheel hub 1; Otherwise, the influence that the rotation of belt wheel hub 1 is not rotated by generator shaft yet.
One-way belt roller is provided with axle sleeve 4, bearing 3 is equipped with in both sides, the two ends external diameter precision-fit of the internal diameter of bearing 3 and positive camber core wheel 2, the internal diameter precision-fit of bearing 3 external diameters and belt wheel hub 1, be used to support radial load, it is excessive to prevent that the positive camber core from taking turns 2 axial clearances, has both guaranteed the fastening of axle sleeve 4, again convenient for maintaining.For one-way belt roller being installed on the prolonged section of generator shaft, there is a hole at positive camber core 2 centers of taking turns, therefore one section screw thread is arranged on this hole, and it is used to guarantee tightening torque, does not need extra fastener positive camber core wheel 2 can be linked to each other with generator shaft is fastening.
