A motor actuator includes a housing, and a plurality of output mechanisms accommodated in the housing. The housing includes a fastening unit that fastens a first case and a second case. Each of the plurality of output mechanisms includes a motor and a plurality of deceleration gears. The motor is supported by the housing. A final state deceleration gear is rotatably supported by the housing. The fastening unit is arranged in a first fastening unit formation range. The first fastening unit formation range is a range formed by connecting contours of a plurality of motors and contours of a plurality of final state deceleration gears, and is a range that surrounds the plurality of motors and the plurality of final stage deceleration gears.

A transmission unit for a vehicle driven by muscle power. The transmission unit has one through shaft and one output shaft, as well as at least two sub-transmissions and at least one intermediate shaft. In the transmission unit at least one of the intermediate shafts and the output shaft is formed as a hollow shaft which is arranged coaxially to another shaft of the transmission unit.

An apparatus for transmitting power from a drive shaft (24) to a seed meter shaft of a seed metering device includes a transmission (26). A transmission housing (28) has a first housing section (30) and an identical second housing section (30). The first housing section (30) and the second housing section (30) together define a first internal passageway (44) and a second internal passageway (50). The transmission further includes a first transmission element (46) rotatably supported by the first housing section (30) and the second housing section (30) in the first internal passageway (44). The first transmission element (46) connects to one of the drive shaft (24) and the seed meter shaft. The transmission further includes a second transmission element (54) rotatably supported by the first housing section (30) and the second housing section (30) in the second internal passageway (50). The second transmission element (54) engages the first transmission element (46) and connects to the other of the drive shaft (24) and the seed meter shaft.

Modular pumps comprising universal gearboxes and crank units and associated methods.

A gearbox comprises a gearbox housing containing a gear train whose shafts are supported by the housing. The housing is fastened to a mounting plate at exactly three attachment points. This three point attachment reduces distortion of the housing that may cause misalignment of individual meshing gears in the gear train, leading to premature failure of those gears transmitting high torque.

A circular spline is secured to a housing. An output member is positioned relative to the circular spline, an outer race of a bearing is secured to the housing, and an inner race of the bearing is secured to the output member. A flex spline is positioned relative to the circular spline and secured to the output member. A wave generator is positioned relative to the circular spline, and a support member, by which the wave generator is rotatably supported, is secured to the housing.

A driving force transmission mechanism is equipped with a first gear attached to a drive source, a second gear enmeshed with the first gear, and a damper shaft enmeshed mutually with the second gear and with a rack member of an air mixing damper. A first locator part formed on the second gear is inserted in a first locator groove in the first gear, while additionally, a second locator part is inserted with respect to a second locator groove in a damper gear. Further, a first narrow tooth formed on the first gear enmeshes with a meshing groove of the first locator part, whereas a second narrow tooth formed on the damper gear enmeshes with another meshing groove of the second locator part.

A gear box for a reciprocating kneader. A primary rotational gear is attached to a gear box primary shaft and rotates in concert therewith. A secondary rotational gear is engaged with the primary rotation gear and rotates therewith. A secondary shaft is attached to the secondary rotational gear and rotates therewith. A primary oscillation gear is attached to the gear box primary shaft and rotates therewith. A secondary oscillation gear is rotationally engaged with the primary oscillation gear and rotates on the secondary shaft. An eccentric is coupled to the secondary oscillation gear and rotates in concert therewith. A yoke is engaged with the eccentric and oscillates on an axis perpendicular to the secondary shaft in response to the lobe. The gearbox secondary shaft moves along its axis in concert with yoke oscillation. A housing is pivotally attached to the yoke and pivotally attached to a casing at a casing.

A gear drive unit (1), for a seat adjuster or a power-assisted steering system, comprised of a spindle (40), on which a drive gear (42) that drives the spindle (40) is provided, a drive assembly (20), which drives the drive gear (42) by means of a driven element (500) and at least one device (30) on which the drive assembly (20) is at least flanged-mounted, and which operationally couples at least the driven element (500) and the drive gear (42). The invention provides that at least one additional support (100, 100) is provided in which the drive gear (42) is mounted, and this support is fastened to the base part (50) and supports the device (30).
