Title:
PROPELLER BRAKE
Document Type and Number:
Japanese Patent JPS58174733
Kind Code:
A
Abstract:
A propeller brake for an engine having a propeller shaft includes a housing (10) and a brake shaft (18) rotatably mounted in the housing (10). The brake shaft (18) is coupled to the propeller shaft to rotate therewith. Also included is a clutch (64, 74) and a lock device (38). The clutch (64, 74) is mounted in the housing (10) and has a spaced plurality of frictional plates (64) for frictionally resisting rotation of the brake shaft (18). This clutch (64, 74) is reciprocatable between an operative and an inoperative position. The lock device (38) is mounted in the housing (10) and can reciprocate between an unlocked and locked position. This lock device (38) can, in its locked position, inhibit rotation of the brake shaft (18). The foregoing equipment can stop a propeller shaft by first frictionally coupling the clutch (64, 74) to the propeller shaft, allowing the coupled portion of the clutch (64, 74) to rotate therewith. The clutch (64, 74) may then be actuated to transmit a resisting torque to stop the propeller shaft. Thereafter, the propeller shaft may be positively and mechanically locked with a locking device (38) to prevent further rotation. A method of braking propellers is also disclosed.
