In an actuator, which can be used, for example, for an electromotive parking brake, and the housing of which is equipped with a gear mechanism, axial and radial bracings of a worm member take place using a bearing bracket, the limbs of which, on both sides, engage the worm member from behind and reach radially beyond its shaft. As seizing protection against a wedging between the worm member and the worm wheel, the bearing bracket can be slightly displaced in the housing. For this purpose, by virtue of the restoring forces exerted by the spring elements, which are then tensioned, the bearing bracket together with the worm member is pushed axially and the worm wheel 20 is turned.

A power transmission device configured to transmit a power inputted thereto from a motor to a wheel is disclosed. The power transmission device includes a first support member, a first gear, a second support member attached to the first support member, a second gear, and an adjustment mechanism. The first gear is supported by the first support member, and configured to rotate about a first axis. The second gear is supported by the second support member, meshed with the first gear, and configured to rotate about a second axis. The second axis is approachable to and separable from the first axis. The adjustment mechanism is configured to adjust a distance between the first axis and the second axis.

Exemplary embodiments are directed to a bell housing with an adjustable register plate for providing adjustable engine crankshaft-transmission alignment. The bell housing includes a body adapted for attachment to an engine block. The adjustable register plate includes a register bore for accommodating the transmission. The register plate can be secured to the bell housing by inserting register plate fasteners through register plate fastener holes into the corresponding register plate attachment holes of the bell housing. The alignment of the register plate relative to the bell housing, and thereby alignment of the transmission with the crankshaft, can be adjusted by loosening the fasteners and moving the register plate laterally, about the register plate fasteners, relative to the bell housing, and then tightening the fasteners to locate the register plate in the desired position.

A planetary gear device for a turbomachine includes a planetary carrier and planetary wheel arranged in an axial direction between two planetary carrier areas connected to a support appliance, with the planetary wheel rotatably mounted on the support appliance. On outer sides facing away from the planetary wheel, the planetary carrier areas include cone surfaces that enclose connection areas with the support appliance, with diameters decreasing with increasing axial distance from the planetary wheel. Cone surfaces of a tensioning appliance radially enclose and are respectively adjusted thereto and act together such that a force that respectively results from an axial tensioning force of the tensioning appliance applied on the cone surfaces of the planetary carrier areas is applied at the connection areas between the support appliance and the planetary carrier areas. The tensioning appliance cone surfaces operatively connect via a coupling element.

An axle system (150) for a vehicle comprises: a differential unit (10) including a first housing (24) and a second housing (20) which rotationally receives at least part of said first housing; at least one drive shaft (11) having one end configured to be connected to a wheel of the vehicle and one end connected to the differential unit (10) and rotationally received in the first housing (24), the drive shaft (11) including at least one joint (110) connecting two portions (114a, 114d) of the drive shaft (11) to transmit rotary motion between said portions; a first bearing (30) secured around the drive shaft (11), placed between the drive shaft and the first housing (24), having an outer diameter (D30) smaller than the radial dimension (D) of the joint (110); a second bearing (40) placed between the first housing (24) and the second housing (20); at least one tightening member (50) to axially lock the first bearing outer ring (32) relative to the first housing (24). The tightening member comprises at least one manoeuvring portion (51) which is arranged in an offset relation relative to the joint (110), when looking axially towards the differential unit (10), so that the tightening member manoeuvring portion (51) is visible and accessible, at least during a tightening phase of an axle system mounting process.

A drive unit is described for driving a transmission unit of an actuator, as well as an actuator that includes a drive unit and a transmission unit. The drive unit includes an alignment element, which is engageable with a mating element of the transmission unit to be driven. The mating element is part of a transmission pin of the transmission unit.

A boom assembly including a boom defining a longitudinal direction pulley rotatably mounted on a pivot pin, the pivot pin having a first end with a first outer surface and a second end with a second outer surface, a pulley frame having a first part for receiving the first outer surface, a second part for receiving the second outer surface, a first hole for receiving a first adjustment rod and a second hole for receiving a second adjustment rod, the boom including a first receiving portion for receiving the first adjustment rod and a second receiving portion for receiving the second adjustment rod, the boom assembly being configured such that adjustment of the first and second adjustment rods causes movement of the pulley in the longitudinal direction.

An actuator including a drive unit for driving a gear unit of an actuator, the drive unit having an alignment element, which engages with a counter element of the gear unit to be driven, and a fixation arrangement/element is provided between the alignment element and the counter element, which allows the alignment element to be fixed in position in the counter element.

A housing for a plastic gearbox and associated plastic gearbox and a robot. The housing includes a body including an inner engaging portion circumferentially arranged on an inner surface of the body, the inner engaging portion adapted to be engaged with a transmission assembly of the plastic gearbox; and an adjusting mechanism arranged around the body and operable to squeeze the body inwardly to reduce an inner diameter of the body. By using the adjusting mechanism to squeeze the body of the housing inwardly, the fit error between the inner engaging portion and the transmission assembly can be compensated in an efficient way. Furthermore, the adjusting mechanism is a part of the housing and thus the body of the housing which is made of plastic does not need to be too thick, which makes injection molding easier and manufacturing precision improved.

Methods, apparatus, systems, and articles of manufacture are disclosed. An example apparatus includes a tubular or cylindrical body including a shaft, a shoulder, and a neck, the shaft coupled to the shoulder, the shoulder coupled to the neck, the shoulder having a greater diameter than respective diameters of the shaft and the neck. The example apparatus includes a plug coupled to the shoulder at a first plug edge and coupled to a first fastener at a second plug edge, the first fastener including a hole. The example apparatus includes a second fastener coupled to the first fastener, the second fastener extending through the tubular body, the plug, and the first fastener.
