Misalignment-compensating coupling

摘要

Such couplings generally serve to compensate for angular misalignments between an input and an output shaft or to take up changes in length. In order to compensate both for an angular and an axis-parallel misalignment between the input and the output shaft, an input flange disc is connected to an outer ring (6) from which two diametrically opposite first pins (5) project inwards and are seated in first sliding bearings (3) of a swinging wobble ring (1). Two further pins (4), diametrically opposite one another, project outwards from the output flange (7) and are seated in second sliding bearings (2) of the swinging wobble ring (1). The axes of the first pins (5) and first sliding bearings (3) are perpendicular to the axes in the second pins (4) and sliding bearings (2) and lie in common plane with them. The misalignment-compensating coupling has a small overall length and permits rotationally rigid, play-free transmission of torques between rotating bodies, which can have both angular and axis-parallel misalignment relative to one another. <IMAGE>
