摘要： A winch has four drive trains of progressively increasing mechanical advantage between its drive shaft (3) and drum (8). If a selector (40) is engaged, rotation of the shaft in successively opposite senses will cause automatically engagement of the first third and fourth trains in sequence. If the selector (40) is not engaged and an override control (80,81,82) is appropriately set, the sequence second, third, fourth trains is followed. But the override may be locked so that only second and third trains are engaged alternately.
摘要翻译：绞车有四个传动系，其驱动轴（3）和滚筒（8）之间的机械优势逐渐增加。如果选择器（40）接合，则轴以相反的方向旋转将导致第一和第四列的顺序自动啮合。如果选择器（40）未接合并且适当地设定了超控控制（80,81,82），则遵循序列第二，第三和第四列。但是可以锁定超驰，以便只有第二和第三列车交替进行。

摘要： A device for transmitting torque between a shaft (1) and an outer annular element (2), in which device the transmission ratio between the shaft and the annular element is determined by the load on the ring. The device comprises at least one eccentric device (5) arranged for rotation with the shaft, and at least one rocker arm (7) which can be activated by the eccentric device and which is provided with an engaging means (11). The engaging means are arranged to be brought into driving contact with the annular ring (2) encircling the shaft (1), by movement of the said at least one rocker arm. The eccentric device (5) is so designed that its effective length varies in dependence on the load required to activate the rocker arm (7). The device can be used to advantage in winches, for example sheet winches on sailing boats.

摘要： A manually powered multi-speed winch has an automatic drive disengagement upon drive reversal which is provided by an axially movable member in one drive train which in a first axial position is engageable for drive transmission through a pawl and ratchet unidirectional drive means. The drive means in its drive-transmitting condition prevents movement of the member away from that first position. Upon drive reversal the unidirectional drive means is ineffective either to transmit drive or to maintain the member in its first position and it moves axially to a second position in which the drive means are disengaged. The member is biased towards that second axial position but is manually movable to the first by a control button accessible at the outside of the winch. The button may be lockable to override the automatic disengagement.

摘要： A deck winch provides three separate speed ratios for its drum when its main shaft is turned. With an external control lever in a neutral position a high speed ratio is attained by rotation of the main shaft in a first direction, resulting in a low drum speed. A medium speed ratio is attained by rotation of the main shaft in a second, opposite direction. With the control lever in its active or low gear ratio position, rotation of the main shaft in the first direction moves the drum at its highest speed relative to the main shaft. When the control lever is in this active position and the main shaft is rotated in the second direction, the control lever is automatically shifted to its neutral position and the medium speed ratio is established. The control lever is connected internally to engage and disengage an idler gear that mechanically interconnects the main shaft with one or several driving gears for the drum. At any time the position of the control lever and the direction of main shaft rotation may be selected to provide any of the three speed ratios.
摘要翻译：甲板绞车在其主轴转动时为其鼓提供三个独立的速比。通过外部控制杆处于中立位置，通过主轴在第一方向上的旋转实现高速比，从而导致较低的转鼓速度。通过主轴在第二相反方向的旋转来获得中速比。在控制杆处于其主动或低档位置的情况下，主轴在第一方向上的旋转以相对于主轴的最高速度移动鼓。当控制杆处于该活动位置并且主轴沿第二方向旋转时，控制杆自动地移动到其中立位置并建立中速比。控制杆在内部连接以接合和脱离将主轴与用于滚筒的一个或多个驱动齿轮机械地相互连接的空转齿轮。在任何时候，可以选择控制杆的位置和主轴旋转的方向以提供三个速度比中的任何一个。

摘要： A multispeed winch having a drum about which a rope or the like may be wound and a drive shaft extending through the drum which is rotatable by a winch handle. Gear trains located within the drum provide two gear ratios between the shaft and the drum. The desired gear ratio is dependent on the direction in which the handle is turned to rotate the shaft. A third, direct drive ratio is achieved by an arrangement which directly connects the winch handle to the drum.

摘要： A drive transmission having a drive shaft and means for rotating the shaft. Spaced dogs are rotated by the shaft and these dogs are biased in a direction substantially inwardly of the axis of rotation of the shaft. The amount of force required to rotate the shaft can be varied. In one embodiment, this may be accomplished by a cam member rotated by the shaft engaging rollers on the dogs, which rollers have tapered surfaces engaging varying irregular surfaces on the cam member. In another embodiment, this may be accomplished by having the cam member rotated directly by the shaft engaging spaced balls mounted in a race housing, the balls being movable in a direction parallel to and at right angles to the axis of rotation of the shaft.

摘要： The invention provides a marine winch driven by a central operating spindle coupled at its lower end to drive reduction gearing in turn coupled to an outer casing of the winch to rotate said casing at one of two alternative output ratios selectable on rotating the operating spindle in opposite directions. The operating spindle has a separate upper portion movable vertically relative to a lower portion and in splined driving engagement therewith. When the upper part of the operating spindle is lowered it is coupled directly to drive the outer casing so as to provide a third, 1:1, output ratio. Unidirectional stepless clutch means are provided in the drive lines to enable the three output ratios to be acheived and also to enable the outer casing to over run.
