Abstract: A gear has a gear body made of a first plastic material. The gear body has an axis of rotation, external toothing arranged around an axis of rotation, a centrally located receiving opening, and an intermediate portion located between the external toothing and the wall of the receiving opening. The gear body is fixedly integrally formed on a support body, which is arranged at least partially in the intermediate portion and is made of a second plastic material having a higher stiffness and lower elasticity than the first plastic material, such that surface portions of the external toothing, of the wall of the receiving opening, of the intermediate portion, and of the support body form a substantially flat end face of the gear. The external toothing is helical toothing with teeth which, at least in portions, extend at a helix angle to the axis of rotation.

Abstract: A shaft, for transmitting a torque and/or an axial force, has a longitudinal shaft axis, a shaft lateral surface, and a shaft end. The shaft lateral surface has at least one recess with an axial recess wall and a radial recess wall adjacent to the axial recess wall. The at least one recess is open axially in the direction of the shaft end. The radial recess wall has a recess radius, such that the radial recess wall has, at least in portions, a concave recess arc shape facing away from the longitudinal shaft axis. A hub has a longitudinal hub axis and at least one hub arcuate portion has a convex hub arc shape facing the longitudinal hub axis. A shaft-hub connection has a shaft and a hub, and an electric actuator has a shaft-hub connection.

Abstract: The present invention relates to a planetary wheel (10) for a planetary gear (14) with a planetary wheel bore (28) which runs coaxially or parallel to the planetary wheel axis of rotation (APR) and which at least partially runs through the planetary wheel axis (22). The invention also relates to a planetary carrier (44) for such a planetary wheel (10), comprising a carrier body (46) with a first disk-shaped body (48) which has at least one first bearing recess (60), which has at least one circumferentially extending first catching projection (64), and with a second disk-shaped body (50) having at least one second bearing recess (62), which has at least one circumferentially extending second catching projection (66).

Abstract: A multi-component gear wheel (10) for a gear assembly of a brake actuator, in particular of a motor vehicle includes a sleeve-shaped support body (100) made of a first plastic material and a gear wheel body (200) firmly integrally formed onto the support body and made of a second plastic material, which has a lower stiffness and higher elasticity than the first plastic material. The gear wheel body (200) has outer toothing (210) and inner spindle-nut toothing (230) for receiving a spindle (50). The spindle-nut toothing (230) is at least partially axially spaced apart from the outer toothing (210) in one direction. The support body protrudes axially at least partially into the region of the helical gear toothing and into the region of the spindle toothing (230).

Abstract: A motor transmission connection arrangement, in particular for use in vehicles, can comprise a motor pot, a brush holder, and a transmission housing. The motor pot, the brush holder and the transmission housing are pluggable to connect with one another, and the motor pot can include a number of centering surfaces, whereby the motor pot with respectively one of the centering surfaces comes into contact both with the brush holder as well as with the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another. The brush holder and the transmission housing can be concentrically oriented to the motor pot. In addition, the present disclosure refers to a sunroof for a vehicle with a motor transmission connection arrangement of this type as well as a vehicle with such a motor transmission connection arrangement.
