Title:
HIGH CAPACITY SCREW DRIVE ARRANGEMENT
Document Type and Number:
WIPO Patent Application WO2004012900
Kind Code:
A3
Abstract:
A drive arrangement for a hemming press uses a ballscrew drive arrangement (12) with a longitudinal axis. A first gimbal (20) connected to the externally threaded screw shaft connects the externally threaded screw shaft to a stationary member (15). The platen (16) is movable with respect to the stationary member. A second gimbal (21) connected to the internally threaded nut connects the internally threaded nut to the platen. The gimbals accommodate transaxial displacement of the screw drive arrangement. A motor applies torque to the ballscrew drive arrangement. Transaxial loading of the screw drive arrangement is accommodated by the first and/or second gimbals. Severe forces resulting from crashes are accommodated by force limiting arrangements and resilient devices.
