Abstract
A motor winch, which is suitable as a sheet or halyard winch (11) for sailing yachts, etc., has an integrated electric or hydraulic drive. The motor (52) is integrated into the winch in such a way that it is located within the winch body and in particular within the winch drum (16). The motor brings about rotation of the winch drum through a multistage gear located in the winch foot (22), optionally assisted by an epicyclic gear (54). A manual operation with a winch crank is made possible by a winch crank nut (32) in the winch head (29). The manual driving shaft is past the somewhat eccentrically positioned motor. A reverse rotation or veering function can be provided in which following the disconnection of the drum locking mechanism, the motor is rotated back in braking manner with a controlled speed.
Claims19
A winch for ropes, having:
- a winch drum (14) rotatable at least in a hauling direction (31);
- a winch foot for fitting the winch to a base part (13);
- a winch gear (84);
- and
- a motor (52) located at least partly in a motor area (47) surrounded by the winch drum (14) and driving the winch drum (14) by means of the gear (84),
- wherein the motor area (47) is provided in a substantially tubular supporting body (44) on which the winch drum (14) is mounted rotatable around a drum rotation axis (28) by means of bearings (46), the motor (52) having a motor axis and being mounted on the supporting body (44) with the motor axis (53) parallel to the rotation axis (28) of the winch drum (14).
