Description
Technical field
The invention belongs to the mechanical transmissioning technology field, specifically, relate in particular to and a kind ofly can realize bidirectional output unidirectional clutch mechanism.
Background technique
Existing overrunning clutch mechanism, one of them important parts are the spline cam one-way element with spline, because one-way element is merely able to the direction rotation by, locking on another direction.When power output (interior ring or outer shroud) the rotating ratio power source (outer shroud or interior ring) of clutch is fast, clutch is in the state of freeing, based on this, thereby realize the overdrive clutch function of overrunning clutch mechanism, because present one-way element is mainly the spline cam type free wheel device, the patent No. is ZL03233130.4, name is called " change gear device with cam type overpass characteristic " and the patent No. is ZL201010539253.8, name is called the clutch of " single-direction and dual-direction clutch mechanism ", it comprises gear, heart section at gear is equipped with the spline cam, this spline cam be evenly distributed in the smooth curved surface that multistage has the lifting characteristic, end face at cam is provided with Ka Tai, between spline cam and gear internal diameter, has retainer, roller is equipped with in dividing equally of retainer in the breach, and each roller and spline cam one section have the lifting characteristic smooth curved surface corresponding; The elastic mechanism that can make retainer roller be pressed to spline cam lift direction is installed between described retainer and the spline cam, and this elastic mechanism is stage clip, this kind structure mainly has the following disadvantages: the first, having in the situation of one-way element, power can only unidirectionally be exported, band moving axis single direction rotation; The second, this kind structure processed complex especially to the processing of retainer, needs to process in the plane the mounting point of groove stage clip in the retainer, the installation step of spline cam etc., so difficulty of processing is large, cost is high, is difficult to volume production.Three, the Ka Tai of the single-direction and dual-direction clutch mechanism in past is provided in a side of on the end face of cam, and cam be kink on axle, so this one-way element can only one-way only operation, unidirectional disengagement or two-way disengagement can not realize two-way working, unidirectional disengagement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of novelty simple in structure, can reliably realizes the overdrive clutch function, and the bidirectional output unidirectional clutch mechanism of long service life.
Technological scheme of the present invention is as follows: the bidirectional output unidirectional clutch mechanism of design, its main points are: comprise gear, in this gear heart section the spline cam is installed, described spline cam is solidly set on the transmission shaft with spline, between this spline cam and gear inwall, retainer is installed, on the excircle of described spline cam, evenly be provided with respectively one group of cam curved surface and projection, described cam curved surface is the smooth curved surface with lift characteristics, and each cam curved surface is that same rotation direction is distributed on the excircle of described spline cam, be respectively equipped with the roller installation gap corresponding with described cam curved surface and stage clip installation gap radially on the described retainer, in described roller installation gap, roller be installed all; In the radially stage clip installation gap of described retainer radially stage clip is installed, this radially stage clip one end be against on the projection sidewall of spline cam, the other end is against on the radially stage clip installation gap sidewall of retainer, this radially stage clip can make described retainer described roller be pushed to the lift direction of described cam curved surface; Be provided with Ka Tai at described gear one end face, be installed with spline housing sour jujube platform mechanism through spline on the described transmission shaft in this card platform outside, spline housing sour jujube platform and described gear card decometer in the described spline housing sour jujube platform mechanism connect.
The present invention adopts above structure, under the effect of stage clip radially, and described retainer and spline cam reverse rotation, thus make retainer push roller the lift direction of cam curved surface to, make the inwall of spline cam, roller and gear clamp state in aggregates.When gear transmission passes to the spline cam and the spline cam is turned clockwise, under the effect of its cam curved surface, roller is outwards pushed, make roller be close to the gear inwall and clamp the rotation of spline protruded wheel, the simultaneously clockwise single direction rotation work of spline cam driven transmission shaft of driving.When transmission shaft rotational speed during greater than the gear rotational speed, the roller of gear inwall is by the low spot direction of spline cam band to cam curved surface, at this moment is between gear, roller, the spline cam three to separate to surmount sliding state.Function based on above structure, when the needs transmission shaft rotates to counter clockwise direction, surmount the effect of sliding because of one-way element, at this moment, when gear transmission rotates to counter clockwise direction, can not be effectively with transmission of power to transmission shaft, when needs are delivered to transmission shaft on to counter clockwise direction gear transmission, only need described spline housing sour jujube platform mechanism is moved to the gear direction, so that spline housing sour jujube platform and described gear card decometer in the described spline housing sour jujube platform mechanism connect, can realize the bi-directional of power.
Preferred as one of described spline housing sour jujube platform mechanism structure: described spline housing sour jujube platform mechanism is by spline housing, spline housing sour jujube platform, axially stage clip and electromagnetic coil consist of, left end at described spline housing is provided with spline housing sour jujube platform, described spline housing through spline package on described transmission shaft, the described axial stage clip of described transmission shaft suit at this spline housing left end, described axial stage clip one end is against on the described spline housing left end, and the other end is against on the described gear-bearing or on the gear face.Described electromagnetic coil is enclosed within on the spline housing outward.Adopt above structure under the effect of axial stage clip, this axial stage clip promotes spline housing and moves right, so that spline housing sour jujube platform separates with the Ka Tai of described gear face.When needs gear driven transmission shaft rotates to counter clockwise direction, only need the energising of the electromagnetic coil in the said structure, thereby under the effect of electromagnetic force, spline housing is moved to the left, so that the spline housing sour jujube platform on the spline housing and the card decometer on the described gear connect, can realize the bi-directional of power.
One group of cam curved surface and two projections on the described spline cam are evenly distributed on the excircle of this spline cam, and described two projections are oppositely arranged, adopt above structure can make retainer and spline cam reverse rotation among the present invention more reliable, simultaneously, when the inwall of spline cam, roller and gear clamped state in aggregates, the power of its combination was more balanced and steady.
Hoop evenly is fixed with four described spline housing sour jujube platforms on the described spline housing left end end face, and hoop evenly is fixed with four described Ka Tai on the described gear right-hand member end face, so can realize the reliable clamping of gear and spline housing sour jujube platform mechanism.
