ABSTRACT:
An elastic axially and angularly yieldable torque transmitting coupling which can be installed between a driving unit and a driven unit has a flange receiving torque from the driving unit and a hub which serves to transmit torque to the driven unit. The hub has an annulus of spherical external teeth in mesh with an annulus of internal teeth on a sleeve-like plastic member of the flange. The flange further includes a plastic supporting member which receives torque from the driving unit and an elastomeric connector which is located between and is vulcanized to the two members. The flange and the hub define a chamber which is surrounded by the elastomeric connector and is ventilated to prevent overheating of the connector. The ventilating system includes a circular array of air-admitting openings in the sleeve-like member radially inwardly of the connector, and a circular array of air-evacuating openings which are provided in the connecting member radially outwardly of the air-admitting openings. The air-admitting openings are in direct communication with the chamber, and the chamber communicates with the air-evacuating openings through first channels in the supporting member and second channels in a washer-like centering element for the supporting member.
