Eccentric wheel can adopt rigidity eccentric wheel or rubber-like eccentric wheel, the rubber-like eccentric wheel is meant that eccentric wheel is made up of two mutually eccentric circle wheels, between two mutually eccentric circle wheels or in two eccentric mutually circle wheels, be provided with elastic material, being connected that shear plane cooperates wherein arranged between elastic material and the steel part.Eccentric one or both ends can be the circle wheels formed of rounded, arc, curvilinerar figure or be Cylindrical object or cone.
Compare with existing coupling clutch, the present invention has following outstanding advantage.
Since the present invention adopted that centripetal moment adds radially direct power and train of gearings be connected transmission structure combining design philosophy, so engaging and disengaging gear is compact to design, the joint efficiency height.
2. eccentric wheel of the present invention has plurality of optional and selects and make up, can satisfy relative angular displacement (maximum can reach 180 ° of aligning strokes turnovers of circling round) the aligning control function that the various bonding state functional requirements of transmission system and transmission housing and aligning wheel disc constituted and design, make clutch have perfect mechanical property.
3. not only fondational structure is succinct in the present invention, and of many uses, and technical connotation is abundant, and therefore the embodiment and the technical functionality that can make up is more, is convenient to satisfy the designing requirement of more technological use and technical functionality.
Below provide the working principle of the present invention as power clutch, brake coupling, free wheel device, safety clutch and energy storage coupling etc. and eccentric wheel and spring.
1) when as power clutch, its working principle is: when clutch for clutch control is faced left the right side when moving axially, produce relative angular displacement motion change between aligning wheel disc and the transmission housing, the binding site state of the wheel disc core wheel that is positioned at the eccentric wheel left side is aimed at or broken away to the core wheel of having adjusted the eccentric wheel right-hand member thus; Wherein wheel disc and eccentric wheel and aligning wheel disc can be done corresponding turnover campaign in the transmission housing, or the driving mechanism of an integral body of sealed one-tenth, have realized the control and the bonding state transmission of clutch thus.
2) when as brake coupling, its working principle is: be based upon on the basis of the structure of above-mentioned clutch and control and combination principle, when being brake axle (or motionless), can implement braking control to the axle that is braked of the other end with first transmission shaft or second transmission shaft, one end.
3) when as free wheel device, its working principle is: be based upon structure and the control and the combination principle of power clutch, and two driving pins of first transmission shaft (bearing pin) respectively with wheel disc (pin dish) on sliding-groove and the basis that is slidingly matched of groove on; When the core wheel aligning of eccentric wheel right-hand member was positioned at the wheel disc core wheel on the eccentric wheel left side, first transmission shaft can be done the rotation that surmounts of left and right sides transmission direction, the transmission of its principle such as pin axle type constant speed output mechanism with respect to second transmission shaft; Otherwise, because in the design of centripetal moment drive mechanism, wheel disc, eccentric wheel and transmission housing have all departed from the driving axle center line of first transmission shaft and second transmission shaft, and transmission housing and wheel disc (or transmission housing, eccentric wheel and wheel disc) quickreturn characteristics and tangential motion inconsistent, therefore when being live axle with second transmission shaft, driving mechanism because of sealed phenomenon realized that clutch can left and right transmission direction in conjunction with transmission.
When the core wheel of eccentric wheel right-hand member had broken away from the wheel disc core wheel that is positioned at the eccentric wheel left side, first transmission shaft and second transmission shaft of clutch then can be realized fully in conjunction with transmission.Because as the free wheel device technical functionality time, the aligning wheel disc is relative static relation with the transmission housing, so the present invention can also be as the free wheel device of simplified structure.
4) when as safety clutch, its working principle is: be based upon on the basis of the structure of above-mentioned 3 kinds of clutches and control and combination principle, because eccentric wheel has transmission combination force coordination function, and wheel disc can surmount motion with respect to eccentric crop rotation, so the present invention can be used as the fixation type safety clutch of simplified structure, or the safety clutch of adjustable safe torque.When adopting simplified structure, the present invention has the combination function of free wheel device and safety clutch simultaneously.
5) when as the energy storage coupling, its working principle is: because the present invention has the centripetal moment torsion structure transmission design of radially direct shearing force and transmission housing, and eccentric wheel has the elastic strain function, therefore can be used as the energy storage coupling of simplified structure or the technical functionality that above clutch can have concurrently.
6) principle of work and power of eccentric wheel and spring: because the eccentric wheel two ends are connected between wheel disc and the aligning wheel disc, so eccentric wheel has friction, reverses, oblique shear power, become axial force and move and elastically-deformable transmission combination force feature.For example the variable axial power motion of conical eccentric wheel also can be coordinated clutch or the eccentric working state that combines with the spring function cooperation of spring, to satisfy the various bonding state functional requirements of transmission system.
