Abstract (en)
[origin: WO03099492A1] Disclosed is a chuck (11) that can be provided with three clamping jaws (13) which are guided in a non-torsional manner within inclined guiding members running at an angle from the longitudinal central axis. Said clamping jaws (13) are fixed to guiding means (19a) that are guided within the inclined guiding members (16, 17). The guiding means (19a) are configured as hollow cylinders and are provided with a connecting bar (22a), one end (23a) of which is connected to the hollow cylinder (19a) while the other end (24a) thereof is connected to a chuck piston (29), both ends (23a, 24a) being fixed in a rigid manner. The connecting bar (22a) is deformable or bendable in a radial direction such that said connecting bar (22a) can transmit power in a compensating manner from the chuck piston (29) to the guiding means (19a) and the clamping jaws (13) also during a relative movement thereof in a radial direction.
