Description
Technical field
The utility model relates to the AC generator for vehicle decoupler, particularly a kind of being installed on the AC generator for vehicle transmission shaft allows the speed of belt pulley because engine speed fluctuations is former thereby with respect to the AC generator for vehicle surpassed distance decoupler of alternator transmission shaft fluctuation.
Background technique
The main effect of AC generator for vehicle surpassed distance decoupler is: 1, reduce the fluctuation of front end train tension force, improve each part life of front end train; 2, reduce the fluctuation of speed of front end train, reduce the noise of front end train; 3, avoid reverse impact, effectively protect generator; 4, reduce the energy consumption that the generator counter-rotating causes, energy saving.It can filter vibration at high speed, also can filter low speed vibration.As Chinese patent CN101111692A, a kind of torque limited decoupler that discloses, its structure comprises: hub, support, torsion spring, belt wheel, clutch spring, torque limiter and thrust washer, and the ring-type thrust washer is provided with against the end of support, and against the inner race of bearing unit.The periphery of thrust washer is circular, and this periphery has step complementally to cooperate with projection.Thrust washer has radially one or more or circumferential serrations, with engage hub and thrust washer is mechanically sealed to hub, thereby prevents to take place between the two relative movement.The thrust washer of this separator cooperates with the projection of support with the step of support by the thrust washer periphery, and there is the unsettled technical problem of dynamic balancing in the course of the work in separator.
The model utility content
The technical problems to be solved in the utility model is: solve existing AC generator for vehicle unsettled technical problem of dynamic balancing in the separator working procedure, the utility model provides a kind of AC generator for vehicle surpassed distance decoupler, and decoupler operates steadily in the working procedure.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of AC generator for vehicle surpassed distance decoupler, has belt pulley, mandrel and be sleeved on the inner headed face of belt pulley and the periphery of mandrel between unidirectional mechanism, mandrel has flange part and axis body portion, unidirectional mechanism has retainer and the thrust washer in the axis body portion that is sleeved on mandrel, retainer does not have axial displacement with respect to mandrel but can relatively rotate, thrust washer does not have axial displacement with respect to mandrel and relatively rotates, the retainer end face has two positioning grooves of circumference uniform distribution, the thrust washer end face has two positioning convex of circumference uniform distribution, and two positioning convex on the thrust washer lay respectively in the corresponding positioning groove.
Further, for reaching simple in structure, simultaneously thrust washer is kept reliably and mandrel between do not have and relatively rotate, retainer does not have axial displacement with respect to mandrel, described mandrel is provided with the spacing convex shoulder of the groove of restriction axially movable spacing block set of retainer or circumference uniform distribution, projection that matches with groove or the retainer groove that matches with spacing block set, arranged on the retainer inner headed face, thrust washer projection that matches with groove or the thrust washer groove that matches with spacing block set, arranged on the thrust washer inner headed face, be equipped with between the axis body portion of mandrel and belt pulley internal surface to have concurrently and prevent that thrust washer from moving axially the ball bearing of effect.
Further, have at least the width of the width of a groove and other grooves different in each groove on the described mandrel, the width of the width of each projection on the retainer and each the thrust washer projection on the thrust washer is suitable with the width of its corresponding groove respectively.Because the locating bump on the thrust washer is positioned at the positioning groove on the retainer, thrust washer does not have with respect to mandrel and relatively rotates, have at least the width of the width of a groove and other grooves different in each groove on the mandrel, therefore in the course of the work, the position that can guarantee the groove that groove width corresponding on projection and the mandrel on the retainer is identical remains staggers and can not rotate to coincidence, thereby can guarantee that retainer can not produce axial displacement on mandrel.
Further, have at least the width of the width of a spacing block set and other spacing block sets different in each spacing block set on the described mandrel, the width of the width of each the retainer groove on the retainer and each the thrust washer groove on the thrust washer width of the spacing block set corresponding with it respectively is suitable.Because the positioning convex on the thrust washer is positioned at the positioning groove on the retainer, thrust washer does not have with respect to mandrel and relatively rotates, have at least the width of the width of a spacing block set and other spacing block sets different in each spacing block set on the mandrel, therefore in the course of the work, the position that can guarantee the spacing block set of same widths corresponding on retainer groove and the mandrel on the retainer remains staggers and can not rotate to coincidence, thereby can guarantee that retainer can not produce axial displacement on mandrel.
The beneficial effects of the utility model are that AC generator for vehicle surpassed distance decoupler working procedure of the present utility model operates steadily, and has solved the unsettled technical barrier of dynamic balancing in the existing AC generator for vehicle surpassed distance decoupler working procedure.
