Abstract: For some powered drum winches, e.g. in sailing boats, it is desirable that the drum can be driven with two different speeds. Basically, this is no technical problem, but it has been difficult to achieve both a high efficiency and a simple construction. It has been proposed that with the use of a plural shaft gear an advantageous result is obtainable in making the gear drive the drum with two different speeds based on a reversible driving motor being driven in one or the opposite direction. This control principle is also used in the present connection in which, however, it is disclosed how the relevant gear can be designed in a compact and inexpensive manner about only a single gear shaft.

The drop box has an input that is angled relative to its output by means of a constant velocity (CV) universal joint. More specifically, a first rotary member is coupled for driven rotation about the rotary axis of the transmission output shaft while a second rotary member is supported for rotation about a second rotary axis that is angled relative to the first rotary axis.

The reversing mechanism is comprised by a right angled bevel gearing with two bevel gears (7, 8), which are freely rotatably mounted on an intermediate shaft (4) and engaged with a bevel gear (6) on the input shaft.
