Abstract
The invention relates to a drive device using circular flexible component to transmit rotational motion, especially a one-way belt pulley of automobile power generator, comprising belt pulley hub and one-way mechanism arranged in the belt pulley hub, where the one-way mechanism comprises outside surface core wheel whose surface has a flat surface and an eccentric circular arc surface, flat spring mounted on the flat surface, roller mounted on the eccentric circular arc surface, shield ring mounted outside the roller, and snap spring mounted outside the shield ring. And it has advantages of relatively simple structure, lower cost, etc.
Description
Affiliated technical field
The present invention relates to transmission device, especially single-way belt pulley of automobile generator with the endless flexible element conveying rotary motion.
Background technique
Single-way belt pulley of automobile generator is by some high-grade automobile extensive uses in the world.This product biggest advantage is, in belt conveyer work, can reduce vibrations and fluctuating, particularly when rotating speed changed, the noise when reducing by the work of belt connection annex increased the mean speed of generator in the engine idle stage, prolong belt life, reduce the vibrations that belt system produces, reduce current fluctuation, prolong the life-span of dynamo governor.The generator mass inertia is removed from the crank rolling velocity nonuniformity of internal-combustion engine.Therefore, in the uneven operation process of crank, have only boost phase just can drive generator shaft.The difference of one-way belt sheave and ordinary straps wheel is, uses one-way belt sheave to rotate to a direction, and moment of torsion is passed to the another one direction.
And existing single-way belt pulley of automobile generator structure more complicated, cost can not be applied on the automobile usually widely than higher.
Summary of the invention
In order to overcome the above-mentioned disadvantage of existing one-way belt sheave, the invention provides a kind of relatively simple for structure, the single-way belt pulley of automobile generator that cost is lower.
The technical solution adopted for the present invention to solve the technical problems is: a kind of single-way belt pulley of automobile generator, form by belt wheel hub and dress unidirectional mechanism within it.Unidirectional mechanism comprises that there is the positive camber core wheel of a plane surface and an eccentric circle cambered surface on the surface, is contained in the flat spring on the plane surface, is contained in the roller on the eccentric circle cambered surface, is contained in the outer back-up ring of roller, is contained in the outer jump ring of back-up ring.
The invention has the beneficial effects as follows to have advantages such as relatively simple for structure, that cost is lower.
Description of drawings
Below in conjunction with drawings and Examples, the invention will be further described.

Among the figure: 1, belt wheel hub, 2, positive camber core wheel, 3, jump ring, 4, bumping post, 5, roller, 6, flat spring, 7, protective cover.
Embodiment
Shown in accompanying drawing 1～6, single-way belt pulley of automobile generator is made up of belt wheel hub 1 and dress unidirectional mechanism within it.Unidirectional mechanism comprises that there is the positive camber core wheel 2 of a plane surface and an eccentric circle cambered surface on the surface, is contained in the flat spring 6 on the plane surface, is contained in the roller 5 on the eccentric circle cambered surface, is contained in the back-up ring 4 outside the roller 5, is contained in the jump ring 3 outside the back-up ring 4.Flat spring 6 has 12, and roller 5 has 12, is evenly distributed in respectively on the plane surface and eccentric circle cambered surface of positive camber core wheel 2.Back-up ring 4 and jump ring 3 respectively have 2, are contained in the right and left respectively.
As shown in Figure 1, protective cover 7 is equipped with in the outside of positive camber core wheel 2 and jump ring 3.Protective cover 7 can prevent the dirt under operating conditions and dabble, and keeps the function of unidirectional mechanism.Protective cover 7 snaps in after one-way belt sheave is contained on the generator shaft.The one-way belt sheave appearance that can see is coated with one deck resin layer.
After the present invention is installed on the automobile generating arbor, two kinds of fastening forms are arranged.Fig. 2 is to use hexagon nut, and Fig. 3 is to use gear.
Working principle of the present invention is summarized as follows: utilize the tension force of flat spring 6, roller 5 is pushed up the peak that the positive camber core is taken turns 2 eccentric circle cambered surfaces.Belt wheel hub 1 can not be moved to this respect.When belt wheel hub 1 rotating speed slows down, when generator shaft inertia rotating speed surpasses the rotating speed of belt wheel hub 1, positive camber core wheel 2 can be carried back roller 5, flat spring 6 tension force are reclaimed, roller 5 can be got back to the minimum point of eccentric circle cambered surface, make roller 5 and belt wheel hub 1 separately, generator shaft can have inertia ground to rotate.The external diameter of positive camber core wheel 2 and the internal diameter precision-fit of belt wheel hub 1 are used to support radial load.For one-way belt sheave being installed to the prolonged section of generator shaft, there is a hole at positive camber core 2 centers of taking turns, and one section screw thread is arranged on this hole, and it is used to guarantee tightening torque, therefore do not need other fastener.Because the axial force that belt produces is absorbed by positive camber core wheel 2 and assembly, therefore axially the maximal clearance has guaranteed that the belt track can freely adjust.There are two back-up rings 4 on the one-way belt sheave both sides, and it is excessive to prevent that the positive camber core from taking turns 2 axial clearances.Jump ring 3 is equipped with in the outside of back-up ring 4, can guarantee that back-up ring 4 is fastening, can make easy to maintenance again.
Claims (2)
