Working Principle of Hydraulic Windlass

Working Principle of Hydraulic Windlass
The hydraulic anchor winch is installed on the main deck of the bow and stern of the ship, and is used for anchoring and mooring of the ship. Hydraulic windlass is mainly a windlass driven by a diesel engine. Usually, the anchor machine and mooring rope machine form an interconnected unit, which is installed at the bow of the ship and used for lifting, anchoring, and mooring. Working principle of hydraulic windlass:
The diesel engine decelerates through two stages of worm gear and gear, driving the winch shaft to rotate. On the winch shaft, a pair of sprockets are looped and a pair of toothed clutches are installed with sliding keys. The handle can slide the clutch axially, allowing it to fit or separate from the sprocket. When lifting the anchor, fit the clutch with the sprocket, loosen the band brake mechanism, and the winch shaft can drive the sprocket to rotate; When anchoring, separate the clutch and sprocket, loosen the band brake mechanism, and then use the self weight of the anchor to release. Release the clutch and use the brake band to brake the sprocket. The winch shaft only drives the winch drum to rotate, which can be used for twisting the cable.

When the ship's anchor windlass is lifted, the clutch is embedded with the sprocket, and the belt brake mechanism is relaxed. The winch shaft can drive the sprocket to rotate; When anchoring, separate the clutch and sprocket, loosen the band brake mechanism, and then use the self weight of the anchor to release. Release the clutch and use the brake band to brake the sprocket. The winch shaft only drives the winch drum to rotate, which can be used for twisting the cable. The sprocket shaft of the electric windlass is installed perpendicular to the deck, and the motor and reducer can be arranged below the deck. This ship's anchor winch not only reduces the floor area but also helps to protect the motor.
