Abstract: An orbital transmission comprising an input element connected to a first power source, a control element connected to a second power source and an output element connected to the control element whereby rotational power is transmitted by an orbiting gear in the output element. The orbital transmission functions based on the relationship of the speed of the orbit of the orbiting gear and the speed of rotation of the input shaft. When the orbiting gear makes one complete orbit in the same time that the input shaft makes one revolution, then the transmission is in neutral and no rotation will be imparted to the output shaft. When the orbiting gear makes less orbits in a unit of time than the input shaft makes revolutions in the same unit of time, the transmission will impart rotation in a first direction to the output shaft which may be forward.

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.

Abstract: When drawbacks which prevent driving of a portion to be driven arise, an excessive load is not applied to components in a drive system so that damage of the components can be prevented. Thrust force, i.e., force in the direction along an axis of rotation (in the direction of arrow B) is applied to a movable worm gear due to the excessive load. When the thrust force becomes larger than urging force of a compression coil spring, the movable worm gear moves axially in the direction of arrow B against the urging force of the compression coil spring. A pin is disengaged from a groove by the axial movement of the worm gear so that the torque of the rotating shaft is not transmitted to the worm gear. As a result, the drive force is not transmitted to the drive system of the downstream side of the movable worm gear. Accordingly, damage such as breakage of teeth of gears due to the excessive load applied to each gear can be prevented.

Abstract: A multicolor image forming apparatus creates a series of different color toner images on a rotatable image member. The toner images are transferred in registration to a receiving sheet carried by a transfer drum. The transfer drum is driven by the image member during transfer but is driven by an independent overridable drive between images. The independent overridable drive includes a worm gear which engages a gear fixed to the transfer drum to rotate the transfer drum. The worm gear is mounted on a rotatable shaft which is driven by a stepper motor. The shaft rotates the worm gear but the worm gear can slide on the shaft or otherwise move axially. A shoulder limits axial movement providing positive drive for the transfer drum. When the image member contacts the receiving sheet and begins to drive the transfer drum it overrides the worm gear and the worm gear separates or floats away from the limiting shoulder.
