Shaft coupling for transmission of rotating motion between shafts of motor and angle measuring device, has coupler and connecting unit, whose groove supporting areas are elastic to clamp balls between areas in tolerance free manner

摘要

The coupling has two connecting units (1, 2) for connecting with respective shafts. Each ball (5.1, 5.2) is rollably supported in axial running grooves (7.7, 7.8) of groove supporting areas (3.3, 3.4) of a coupler (3) in one side and in axial running grooves (7.3, 7.4) of groove supporting areas (3.7, 3.8) of the connecting unit (2) in another side, for a rotary rigid connection between the coupler and the connecting unit (2). The groove supporting areas are elastically designed in a radial springy manner to clamp the balls between the groove supporting areas in a tolerance free manner.
