Embodiment
Present embodiment pushes and reverses the composite elastic coupling, comprises input disc 1, output disc 2, extruding block rubber 3 and reverses transmitting assemblies;
Said input disc 1 is provided with the curve bath 1a that extends along its circumferencial direction; Said curve bath 1a is four and evenly arranges along input disc 1 circumferencial direction; Said extruding block rubber 3 is arranged among the curve bath 1a, and said output disc 1 is provided with the projection 2a that stretches among the curve bath 1a and can move along curve bath; The extruding kind of drive is: thus input disc 1 rotates and drives extruding block rubber 3 and rotate, extruding block rubber 3 turn to output disc 2 on projection 2a when contact, extruding block rubber 3 just promotes projection 2a rotation, thereby power is passed to output disc 2 from input disc 1;
The said transmitting assemblies that reverses comprises first driver blade 5 that reverses rubber sleeve 4, is fixedly connected with input disc 1 and second driver blade 6 that is fixedly connected with output disc 2, and the two ends of reversing rubber sleeve 4 are fixedly connected with second driver blade 6 with first driver blade 5 respectively; Reversing the transmitting assemblies kind of drive is: power is successively through input disc, first driver blade 5, be passed to output disc 2 after reversing the rubber sleeve 4 and second driver blade 6.
In different mode of executions, the quantity of curve bath 1a can be adjusted, but its quantity is at least two.
This extruding and reverse the composite elastic coupling, input disc 1 can be connected with power input shaft through bolt, and output disc 2 is provided with splined hole, and itself and output shaft pass through spline fitted; Certainly in different mode of executions, this extruding with reverse the composite elastic coupling and also can be connected with input shaft, output shaft through other Placements.
This extruding and reverse the composite elastic coupling; With the extruding block rubber power is passed to output disc from input disc through reversing transmitting assemblies; Owing to reverse the torsional deflection of rubber sleeve 4; Make this extruding and reverse the angular displacement error that the composite elastic coupling can compensate drive line; Simultaneously all have the buffer shock-absorbing function with extruding block rubber 3 owing to reverse rubber sleeve 4, so this extruding and reverse that the composite elastic coupling has that rotational noise is low, vibration is little and advantages such as coupling long service life.
