A drive transmitter includes an internally toothed gear, a first support shaft to rotatably support the internally toothed gear without using a bearing, a drive source to apply a driving force to the internally toothed gear, a rotary body to which the driving force is transmitted via the internally toothed gear, and a grease retainer disposed on the first support shaft and to retain grease on at least one of a portion of the first support shaft facing the internally toothed gear and a portion of the internally toothed gear facing the first support shaft. An image forming apparatus includes the drive transmitter.

A drive transmission unit is described that includes a drive source, and a rotatable drive transmitting member to transmit a driving force from the drive source. The drive transmitting member includes a bottom part intersecting an axis of the drive transmitting member, a circular transmitting part extending from the bottom part in an axial direction of the drive transmitting member and including an internal toothed surface on an inner circumferential surface of the transmitting part to mesh with a first member, and a first projecting part and a second projecting part projecting in opposite directions from the bottom part along the axial direction of the drive transmitting member and having different diameters.

A transmission turbo machine integrates drive units and/or driven units into a machine train via a transmission. The integrated transmission substantially comprises a central large wheel with a shaft and a plurality of pinions with pinion shafts. The large wheel is operatively connected to the pinions, and the ends of the pinion shafts are operatively connected to a drive unit and/or driven unit. The shaft of the large wheel is operatively connected to a drive unit and/or driven unit. The invention is characterized in that the drive unit and/or driven unit is an axial expander which is mounted in a cantilevering manner in one or more stages.

An electric device is provided. The device includes an electric machine having a rotatable first shaft extending from an end of the machine. The device also includes a gearbox operably connected to the electric machine. The gearbox includes a first gear rotatably supported in the gearbox and a first gear connectable to the first shaft. The first gear is adapted to mesh with the second gear. The electric machine and the gearbox are adapted to drive a pump.

A method for producing an adjustment fitting, particularly for a vehicle seat is provided, whereby an outer wheel is associated with a first fitting part, the wheel having inner toothing, and having an inner wheel that can be associated with a second fitting part, the wheel having outer toothing, wherein the inner wheel having the outer toothing is inserted into the outer wheel having the inner toothing eccentrically to a rotational axis in the manner of a wobble mechanism, wherein partial eccentric elements are inserted rotatably with respect to each other in an eccentric receiving chamber formed between the rotational axis and the inner wheel so as to produce variable eccentricity, wherein a transmission element having an engagement element for actuating the partial eccentric element is inserted such that the engagement elements interacts with a catch of the partial eccentric element. In spite of the production tolerances of the components, overall higher quality and higher operational safety of the produced adjustment fitting are to be achieved. For this purpose, the geometry of the partial eccentric element is measured, and the geometry of the transmission element is individually adapted according to the data of the measurement before inserting the transmission element.

An assembly adapted to replace an automobile differential's spider gears, locking the axles together. The present invention comprises a pair of outer drive flange members that are adapted to engage with a pair of wedge locking members within the carrier of an automobile differential, replacing the differential's stock planetary or spider gears. The present assembly locks the rotation of the rear axles together, applying power equally to both wheels and enhancing the performance of the automobile during competitive drag racing events, without requiring expensive custom installation from a specialist.
