Patent DE-4409603-A1 (DE)
Title: Device for clamping a tool or a workpiece
Inventor: LINDSTROEM STEFAN
IPC: B23B31/117
Filed: 1994-03-21
Abstract: The device has a chuck in the form of a hydraulic clamping sleeve (8) which comprises a thin inner sleeve (11), a rigid outer sleeve (10) and a plastic or hydraulic pressure medium (13), the latter being enclosed between the two sleeves. The thin inner sleeve (11) serves both to centre and clamp in place a rotating tool (16) or a workpiece when the hydraulic pressure medium (13) is pressurised. The chuck is connected to a mounting taper (5) or to the machine spindle (1) by welding or brazing. It has in its periphery a bore which forms an access opening to any pressure device (15) for pressurising the hydraulic pressure medium (13) for the clamping sleeve. Furthermore, the chuck is provided with a protective ring (17) all round its periphery. The protective ring (17) can be rotated and can be locked in at least two positions, in which case it covers the bore for the pressure device (15) in the one position and opens an access to the pressure device (15) in the other position. Furthermore, the chuck (8) can have at least one bore for fine balancing, this bore being made in the material of the chuck and likewise being covered by the protective ring (17). <IMAGE>

Abstract: Lorsque dans les machines électriques synchrones, la partie centrale (5) du moyeu (4) du rotor à jante empilée (3) est fixée des deux côtés par des moyens de fixation (11) à la collerette (16, 17) de l'arbre creux, ces moyens sont fortement sollicités par la dilatation de la jante feuilletée (9). Une nouvelle forme du moyeu peut l'éviter. La partie centrale (5) du moyeu (4) est pourvue d'une tubulure (13) disposée axialement qui porte les collerettes (16, 17) supportant les moyens de fixation (11) à l'arbre creux (1, 2). Les sollicitations dues à la dilatation seront reportées sur la tubulure (13) par la flexion de celle-ci, déchargeant ainsi les moyens de fixation. Une telle machine convient en particulier pour un générateur hydro-électrique à arbre vertical creux.
