NEW CONCEPT 3
轮机英语25
The majority of automatic mooring winches(自动绞缆机)
are spur geared to improve the
backward efficiency of the gear train(传动机构) for rendering(放缆), the gearing and
Worm geared automatic mooring winches are uncommon as the multi-start (多头螺纹) feature required to improve gear efficiency reduces the main advantage of the worm gear i.e., the high gear ratio.
There is some variation in detail design of cable lifters and in their drives.
Due to the low speed of rotation required of the cable lifter whilst heaving anchor(起锚), (3~5 r/min) a high gear reduction is needed when the windlass is driven by a high speed electric or hydraulic motor.
Mooring winches Mooring winches provide the facility for tensioning the wire up to the stalling capacity(堵转力矩) of the winch, usually 1.5 times full load, thereafter the load is held by the prime mover brake or barrel brake when the power is shut off.
