Description
Technical field
The present invention relates to a kind of multi-freedom degree big torque clutch, have more biased in particular for working as speed reducer and working machine or electrical axis, and the coupler structure of transmitting large torque belonging to mechanical field.
Background technique
Current coupling major function is divided into two classes, and a class is energy transmitting large torque, but the coupling making up axis error of centralization that can only be less, such as crown gear coupling etc.; Another kind of is to make up larger axis line error, but the moment of torsion being generally used for transmission is less, such as cross universal coupling, when transmit comparatively high pulling torque time, the size of coupling and weight are often all very large.At the axis of some workplace working machine and speed reducer and decentraction, and be engraved in change during distance between two axis, such as, be engraved in change during action roller shaft distance between centers of tracks in roll mill speed reducer output shaft line and working machine, it is very necessary at this moment developing a kind of coupling that can meet this operating mode.
Summary of the invention
The object of the invention is to: exist for current coupling or transmitting large torque, but can only be less make up axis error of centralization, maybe can make up larger axis line error, but the moment of torsion being generally used for transmission is less, problem, a kind of new multi-freedom degree big torque clutch structure is provided.
The object of the present invention is achieved like this: a kind of multi-freedom degree big torque clutch, comprise prime mover half-coupling and load half-coupling, they are all provided with the coupling hole be located by connecting with corresponding shaft, it is characterized in that: coupling also comprises a buoyant beam, eight flexural pivots and four connecting rods, and connecting rod two ends are provided with hinged mounting hole; Described prime mover half-coupling and load half-coupling are equipped with a pair symmetrical wing arm, and a pair symmetrical wing arm lays respectively on the elongation line of coupling hole diameter, and the end of a pair wing arm is provided with a flexural pivot; Buoyant beam two ends are equipped with two flexural pivots; After prime mover half-coupling is fixedly connected with the axle of load with prime mover by coupling hole respectively with load half-coupling, buoyant beam is held between prime mover half-coupling and load half-coupling, and two flexural pivots of buoyant beam are docked with the flexural pivot of prime mover half-coupling and load half-coupling respectively by two connecting rods.
In the present invention, described flexural pivot comprises the dunnage at joint shaft bearing, bearing pin and bearing pin two ends, wherein the dunnage at bearing pin two ends is all solidified as a whole with corresponding wing arm end or corresponding buoyant beam end, the dunnage at bearing pin two ends is equipped with corresponding bearing pin mounting hole, joint shaft bearing is supported between two dunnages by bearing pin and bearing pin mounting hole.
In the present invention, be equipped with limiting board outside the bearing pin mounting hole of the dunnage at bearing pin two ends, limiting board is fixedly connected with corresponding dunnage by equally distributed bolt.
In the present invention, in prime mover half-coupling and load half-coupling, the dunnage of the bearing pin outboard end be in is corresponding wing arm, and the dunnage being in bearing pin medial extremity is solidified as a whole by the support on wing arm and wing arm; Be equipped with joint shaft bearing mounting groove at the end face at buoyant beam two ends, the dunnage at bearing pin two ends is the cell wall of joint shaft bearing mounting groove; Each flexural pivot force bearing point after being connected with connecting rod is all tending towards on same plane with buoyant beam.
In the present invention, the hole wall of corresponding joint shaft bearing both sides of the hinged mounting hole of connecting rod is respectively equipped with the positioning boss of joint shaft bearing and is furnished with the restraining groove of snap ring.
In the present invention, prime mover half-coupling and the coupling hole of load half-coupling are with the Placement of corresponding shaft or be connected for key or connect for interference, or are the non-geometry of the circle docking of hole axle coupling.
In the present invention, the non-geometry of the circle docking of hole axle coupling refers to, when the cross section of axle is square, or semicircle, or during triangle, the geometrical shape of coupling hole and their Corresponding matchings.
The invention has the advantages that: because between the load that the present invention relates to and prime mover, the connecting link of coupling is the movable connection method that connecting rod and flexural pivot build, the axle of figure-8 structure to load and prime mover that connecting rod and flexural pivot build does not have position-limiting action, therefore, not needing to adjust the distance between shafts between alignment between the two and diaxon when assembling, in using, can meet particular job condition that axis does not depart from and both distance between shafts change of prime mover and load yet.Because the dunnage of flexural pivot by joint shaft bearing, bearing pin and bearing pin two ends forms, by each connecting rod and joint shaft bearing, the both wings arm to load half-coupling directly draws prime mover half-coupling both wings arm, larger moment of torsion can be transmitted, the present invention is compared with transmitting the coupling of same torque, compact structure, installation and maintenance is all very convenient, and volume and weight is obviously less.
