Drive unit for e.g. dynamometer, has flywheel pivoted by bearing device with respect to stator, where bearing device includes rotatable rolling bodies that are arranged spaced from each other by bearing ring in circumferential direction

摘要

The unit has a stator (2), and a flywheel (4) that is pivoted by a bearing device (8) with respect to the stator, where the flywheel is arranged radially within the stator. The bearing device surrounds the flywheel and includes rotatable rolling bodies (10), where the stator has a bearing surface (12) that is arranged in an area of its inner surface and the flywheel has another bearing surface (14) that is arranged in an area of its peripheral surface for the rolling bodies. The rolling bodies are arranged spaced from each other by a bearing ring (20, 22) in a circumferential direction.
