Abstract
A center drive support for supporting a crankshaft during machining in a machining device comprises a rotatably drivable support member and a drive unit. The rotatably drivable support member has a carrier with at least two clamping elements with clamping ends. The clamping elements are displaceable between a clamping position and a release position for the crankshaft. The clamping elements clamp the crankshaft between their clamping ends. The drive unit is connected to the clamping elements for applying a required clamping force in the clamping position during rotation of the support member. The drive unit includes a clamping motor and a drive shaft connected to the clamping motor. It further includes a gear unit connected between the drive shaft and the carrier. The gear unit, during machining of the crankshaft in the clamping position, follows the rotation of the support member against the toque of the clamping motor.
