A mounting assembly for a coupler mechanism of a motor vehicle has at least a plurality of components which are to be mounted during mounting of the coupler mechanism as the latter is being assembled. A shifting element corresponds to one of the components which is configured to shift a clutch of the coupler mechanism. A first spring element corresponds to one of the components which is received displaceably on the shifting element and which is configured for at least indirect spring force-preloaded support on a housing of the coupler mechanism. The mounting assembly also has a mounting device which is separated from the components in the finally produced state of the coupler mechanism and has a securing element with a first securing element end and a second securing element end. The first securing element end is reversibly coupled releasably to the shifting element and, as a result, secures the first spring element against sliding off the shifting element during mounting.

A jig includes: a first gear part that can be meshed with an input gear disposed in a casing by being inserted into the casing from the outside of the casing; a torque application part that is fixed to the first gear part, is disposed outside the casing in a state in which the first gear part is meshed with the input gear, and is capable of applying a torque about a first axis, which corresponds to an axis of the first gear part, to the first gear part; and a phase indicator provided on the torque application part to indicate the phase of the first gear part about the first axis.

A multipurpose protective cap for a transmission prior to and during assembly with a drive shaft has a base portion having a cylindrical cross-section of a first inner diameter. The base portion comprises a side wall defining the cylindrical cross-section and having an outer edge and an inner edge, and a membrane spanning the cylindrical cross-section of the base portion at the outer edge of the side wall. An insertion portion extends from the base portion opposite the outer edge, the insertion portion having a cylindrical cross-section of a second inner diameter, the second inner diameter smaller than the first inner diameter. A contamination removal portion is formed in an interior surface of the insertion portion and configured to remove debris as the drive shaft passes through the insertion portion. A handle extends from the side wall of the base portion.

An electronic device may comprise: a first housing; a second housing movable relative to the first housing in a first direction or a second direction opposite the first direction; a driving unit including a first gear and a motor for rotating the first gear and provided in the first housing; and a rail unit including a second gear and moves the second housing while the second gear is engaged with the first gear and moved by rotation of the first gear. The rail unit may comprise: a base coupled to the second housing and to which the second gear is slidably connected in the first direction or the second direction; a fastening member connecting one end of the base to the second housing; and a buffer member provided between the second gear and the fastening member to buffer an impact applied to the second gear.

In at least one embodiment, the assembly for a gearbox for a wind turbine includes a housing element, a rotational element, a bearing, a first connection feature for connecting the housing element to a connection element and a second connection feature for connecting the rotational element to the connection element. The rotational element is arranged rotatably with respect to the housing element via the bearing. At least one of the first and the second connection feature is configured to form a movable, form-fitting connection such that, when the housing element and the rotational element are connected to the connection element via the first and the second connection feature, a relative axial movement between the rotational element and the housing element is prevented but a relative rotation between the rotational element and the housing element is enabled.

A roller screw drive, in particular in the form of a planetary roller gear, a roller screw drive or an inverse roller screw drive, including a threaded spindle with an external thread, a plurality of planets, and a spindle nut with an internal profile. Each planet has a profiled central section, which engages in the external thread of the spindle nut, and two equally profiled side sections which are thinner than the central section, which side sections each mesh with a section of the internal profile of the spindle nut. End sections of each planet adjoining the side sections are held in recesses of separate guide discs. Each recess for holding the planet has an assembly holding contour and an operating holding contour separated therefrom.

A geartrain assembly includes a first gear, a second gear, and a third gear. A linkage connects the first gear and the second gear, and defines an assembly location of the third gear to connect the third gear to the first and second gears in a manner that minimizes a backlash in the geartrain assembly.
