Winch

A winch ( winch English: "Morning Glory " ) is a common, especially in the shipping winch used to transfer large tensile forces. In ships it is a part of the cargo-handling gear, fishing it is used for the machine in the nets.

Winches while sailing

When sailing winches serve the operation of sheets, halyards and other Tauwerksleinen. A previously more common name is wind.

A line is to the other winch to a winch not wound in the difference, but only down to a few turns around a drum which can be rotated with a crank handle. The winch drum consists of a roughened or corrugated metal cylinder that can be rotated in one direction only. In the other direction of rotation pawls prevent that the rope unwinds again. The loose leash end must be kept taut to increase the friction between the winch and rope. In Selftailern ( self tailing winches ) a conically profiled and sculpted to increase the friction idler pulley takes the lead and hinders slipping the leash. The cone also allows ropes of different diameters can be performed using a winch.

To increase the torque winches often have a built-in gear, the stocky several revolutions of the crank in a smaller number of drum rotations. In Zweigangwinschen the transmission has two translation stages. Depending on the direction of rotation of the crank different rotational speeds and torques can be achieved thereby. On larger yachts winches are driven by an electric motor or hydraulic.

Most winches are right-handed, so the line wrap in a clockwise direction.

Pole or halyard winches are mounted on the mast of a sailing boat or ship, where they serve the operation of the traps. Simple, mostly crank and gearless winches dinghies are called Knarrpoller. ( Coffee ) grinder (English, actually " ( coffee ) mills " ) are large, mounted on a column winches on racing yachts, which are usually operated by two crew members. Large Winches for hawsers on traditional sailing ships and commercial shipping are spills. With a windlass (or Capstan) anchor chains can be reversed.
