Drehkupplung mit Lenkern.

摘要

This invention relates to rotary couplings (4,11) for transmitting torque between rotatable drive (61,12) and driven means (3,13). The couplings (4,11) include links (5,25) which each including an axially stiff body (25c) connected at respective ends to the drive and driven means by respective elastomeric bearings (35,36), which allow pivoting of the body about respective axes which are parallel. At least one of the bearings (35,36) also allows further pivotal movement of the body (25c) about a third axis which is orthogonal to one of the other axes. This elastomeric bearing (35) is so formed as to accommodate the link motion necessary to effect a substantially constant velocity connection between the rotatable members (4,11;3,13).
