Abstract: A clutched actuator for use in a transfer case is disclosed which may be used in conjunction with electronic traction control systems and anti-lock braking systems where the clutched actuator system is required to quickly disengage the four-wheel drive of the vehicle. The clutched actuator is operably coupled to the transfer case of the vehicle drive system through a sector plate. The clutched actuator includes a worm drive motor assembly providing the base driving mechanism, a clutching mechanism, and a gear reduction mechanism for reducing the torque capacity required of the clutch mechanism.

The worm gear is non-backdrivable such that the motor need not provide a holding torque.

Abstract: A new type of apparatus for transmitting rotation utilizing an oscillating input utilizes a self-locking worm (1) and worm gear (3) combination with different types of means for rotating said worm about its axis of rotation relative to said worm gear described. An input to the worm gear (3) is transmitted without relative movement to the thread of the worm (1) to cause the thread and hence the rotor to rotate about an axis of the worm gear. The means preferably rotates the worm thread relative to the worm gear teeth under certain conditions when it is not desired to transmit rotation.

Abstract: An epicyclic drive train arrangement having a plurality of output drive members which may be selectively driven from a single input drive member. A frame equipped with two pawls is operated by a single solenoid and spring combination.

The action prevents rotation of the selected gear while the pawl is engaged. The unselected pawl disengages its mating gear thereby allowing it to freely rotate. Multiple epicyclic drive train arrangements may be configured so as to drive a plurality of sheet feeding apparatuses in an electrophotographic printing machine.

Abstract: An automotive final drive assembly which utilizes a worm gear system for speed reduction between a vehicle's engine and drive wheels. The final drive assembly is capable of reducing the high speed from the engine and delivering it to the vehicle's drive wheels, all within an extremely compact space. Furthermore, the large contact area between the thread of the worm and the teeth of the worm gear provides for a high load capacity with relatively low friction, such that the final drive assembly is efficient and operates at lower temperatures. Finally, the worm gear is a ball worm gear having a spheroidal shape. As a result, the structure of the final drive assembly is simplified and suitably rigid to maintain the threads of the worm in mesh with the teeth of the worm gear.

Preferably, a cylindrical surface on a mounting washer mates with a cooperating cylindrical surface formed in the differential housing to permit slight positional-adjustment movements of the combination gear, such adjustment movements being limited to a plane perpendicular to the axis of the side gear with which the combination gear is associated.
