A swash-plate-type gearing for adjustment devices includes a housing; an outer part, which has an inner toothing concentric with a joint axis; and an inner part with an outer toothing concentric with an eccentric axis, which runs parallel to the joint axis, offset by an off-centre distance. The gearing also includes an engagement region, in which the outer toothing is engaged with the inner toothing and which is located on a straight line intersecting the joint axis and eccentric axis, in each case at a right angle, with the eccentric axis lying on this straight line between the joint axis and engagement region; and a free space located 180° opposite the engagement region and on the straight line, in which free space the outer toothing is disengaged from and at a distance from the inner toothing. A locking part is provided having a locking region located in the free space.

A gear drive, such as for an actuator, is a right-angle drive where toothed outer ridge of a face gear is coupled to teeth of a motor output shaft, and a set of planetary gears are engaged with a central sun gear of the face gear. The sun gear and planetary gears are aligned with the motor output shaft. For instance the motor output shaft may be substantially in the same plane with the sun gear and the planetary gears. From another standpoint the axis of the motor output shaft may intersect the sun gear, as well as intersecting a volume that the planetary gears sweep through as the planetary gears engage the sun gear.

A dual motor electric drive axle apparatus is disclosed that is enclosed within a single housing. First and second motors are disposed in the housing. First and second rotor shafts, and first and second chain drives including first and second driving sprockets are connected to the first rotor shaft. A first chain, and a first driven sprocket are connected to the first and second driving shafts by first and second chain respectively. First and second planetary gear sets having first and second input shafts are connected to the first and second driven sprockets. First and second output shafts are connected to first and second constant velocity joints that are located outside the housing. First and second axles are connected to the first and second constant velocity joints and are adapted to rotate first and second wheels respectively.

A torque load binder for changing tension in a chain or strap securing a load to a vehicle or support surface. The load binder includes a housing with an internal gear mechanism and a connector mechanism operatively engaged with the gear mechanism and extending outwardly from the housing. A high speed first driveshaft and a lower speed second driveshaft on the load binder are selectively individually actuated to effect movement between first and second end linkages of the connector mechanism. The first driveshaft effects movement between the first and second end linkages at a first speed and the second driveshaft effects movement between the end linkages at a lower second speed. Rotation of either of the first or second driveshafts actuates the connector mechanism, changing the distance between the first and second end linkages, and thereby changing the tension in the tie-down.

A drivetrain for coupling a motor to a mixer shaft within a mixer includes a sun gear connectable to a rotor of the motor. The drivetrain also includes a plurality of stepped planetary gears. Each of the stepped planetary gears includes a first tooth section and a second tooth section. A first ring gear is mounted such that the first ring gear is fixed. The first ring gear and the sun gear are meshed with the stepped planetary gears at the first tooth section. A second ring gear is meshed with the stepped planetary gears at the second tooth section. The sun gear, the stepped planetary gears, the first ring gear, and the second ring gear collectively form a single stage planetary gear set of the drivetrain.

A gear backlash control mechanism includes a base, a worm gear pivoted to the base, a driving member, a biasing member, a driving worm set having a first shaft, a first worm and a first linkage structure jacketing the first shaft, and a driven worm set having a second shaft, a second worm axially slidable on the second shaft, and a second linkage structure fixed to the second shaft and linked to the first linkage structure. The driving member rotates the worm gear via the first shaft and the first worm and rotates the second worm via the first and second linkage structures and the second shaft. When the worm gear rotates, the first worm abuts against a first tooth surface of each tooth of the worm gear sequentially, and the biasing member pushes the second worm to abut against a second tooth surface of each tooth sequentially.

A driving module including a driving source configured to generate power, a gear train including a decelerating gear set configured to receive driving power from the driving source and a ring gear attached to one side thereof, and a rotary joint including at least one planetary gear configured to rotate using power received from an output end of the decelerating gear set and to revolve along the ring gear is disclosed.

Disclosed is a four-way reversing valve, including a valve body, a motor transmission structure, and a reversing valve disc; the valve body includes a valve seat, an insulation sleeve welded to upper end surface of the valve seat, a D pipe, an S pipe, a C pipe, and an E pipe connected to lower end surface of the valve seat; the motor transmission structure includes motor worm gear and shaft transmission assembly and a planetary gearbox kit; the motor worm gear and shaft transmission assembly is sleeved onto upper external wall of the insulation sleeve through shaft hole of an external drive sprocket, and a non-through blind-hole is formed in a valve seat center; a central shaft is embedded into the blind-hole, and the central shaft connects the reversing valve disc and the planetary gearbox kit; the reversing valve disc and the planetary gearbox kit are inside the insulation sleeve.

A drive axle for a work machine for driving wheels that are coupled to the drive axle. The drive axle includes a spur gear stage with an input shaft. A differential gear unit couples to the spur gear stage and to the wheels via wheel drive shafts. The drive axle further includes a reduction gear unit with an output element couples to the input shaft of the spur gear stage—and an input element which couples to an output shaft of an electric drive machine.

An apparatus for use in turning steerable vehicle wheels includes a steering column having a pinion connected with a vehicle steering wheel such that rotation of the steering wheel results in rotation of the pinion. An electrically powered steering unit includes an electric motor having a first output shaft rotatable about an axis. A first planetary gear stage has a first gear reduction ratio and is driven by the first output shaft. A second planetary gear stage is driven by the first planetary gear stage and the pinion and has a second gear reduction ratio different from the first gear reduction ratio. A second output shaft is driven by the second planetary gear stage and coupled to the steerable wheels such that rotation of the second output shaft affects steering of the vehicle wheels.
