Purpose of the present invention is achieved through the following technical solutions:
A kind of heavy transmission safety elastic coupling is characterized in that: comprise that correspondence has the input coupling sleeve of large and small axial center hole, output tie-plate and is locked in the output flange of exporting on the tie-plate; The output tie-plate is sheathed in the input coupling sleeve rotationally, and output tie-plate center hole week is along being provided with the axial bulge loop that is engaged in the input coupling sleeve center hole; The input coupling sleeve end face relative with the output tie-plate is provided with annular groove, output tie-plate cover cap annular groove forms a sealing ring cavity, being evenly equipped with the staggered even number parting bead radially that is fixed on input coupling sleeve, the output tie-plate in the ring cavity, installing flexible snubber block between the adjacent parting bead respectively.
Have spacing between the center hole bulge loop of the center bore inner wall of described input coupling sleeve and output tie-plate, be set with bearing in this spacing.
Described elastic shock attenuation piece adopts urethane rubber (UR) to make, and its pretension is clipped between the two adjacent parting beads; The inside and outside sidewall middle part correspondence of elastic shock attenuation piece is provided with concave-arc part.
The utlity model has following beneficial effect:
Between the adjacent parting bead of the elastic shock attenuation piece pre-tightening apparatus of this heavy transmission safety elastic coupling in the sealing ring cavity+; pass through the transmission of elastic shock attenuation piece between input coupling sleeve, the output tie-plate; relax and impact and absorbing vibration; it is compared with existing elastic coupling flexible coupling; have good buffering and damping performance, non-slip, improve safety coefficient and working stability greatly; prolong the working life of coupling, effectively protect the safety of motor, gearbox simultaneously.
