A dual function gearbox generates two separate output rotational motions from a single input rotational motion. First and second rotatable housings comprise corresponding first and second internal gears, with the internal gears having different pitch diameters. A drive shaft is disposed within the housings, extending though openings within opposite sides of housings, with an eccentric rotor disposed around the drive shaft. The eccentric rotor is in operative contact with a differential gear ring comprising first and second external gear rings having different diameters, with the first and second external gear rings engaging corresponding first and second internal gears. When rotational energy is imparted to one end of the drive shaft, the gearing arrangement imparts a rotational motion to either the first or second rotatable housing, with the housing rotating around the other end of the rotating drive shaft, which can extend outside of the dual function gearbox. Thus, the dual function gearbox generates two output motions: high torque rotation of the rotatable housing; and rotation of the drive shaft which can be used as an input rotation to additional dual function gearboxes.

Dual function gearbox, gearbox system and method

An adapter is provided for a removable information storage device in an information storage and retrieval system or control system. There is a mounting bracket permanently installed in a half-height space and hooked up to the wires already provided for in the system. A separate box-like cartridge component permanently houses the information storage device. The cartridge has electrical connections for connecting the information storage device to a mateable connector mounted on the back face of the cartridge. The mounting bracket likewise has a complementary mateable connector mounted on it so that both connectors will plug together whenever the cartridge is fully inserted into the bracket. This completes the electrical connections and power supply between the information storage device and the system allowing the information storage device to be used as if it were permanently installed in the system. The walls of the cartridge and the bracket engage through a pair of tracks and guideways to align the cartridge as it is inserted in the bracket and to match up the mateable connectors.
