Abstract: The present invention relates to a gear ring carrier part (10) for a two- or multi-component gear (11), the gear ring carrier part (10) having a circular ring section (12) rotating in the circumferential direction about an axis of rotation (A), a gear ring (14) arranged radially on the outside of the circular ring section (12), and an extension (16) extending radially inward from the circular ring section (12), the extension (16) having a first extension face (30) and a second extension face (32), a number of first ribs (34) and an equal number of first pockets (36) being arranged on the first extension face (30), and/or a number of second ribs (38) and an equal number of second pockets (40) being arranged on the second extension face (30), the first ribs (34) and the first pockets (36) and/or the second ribs (38) and the second pockets (40) each extending radially and being arranged adjacent to one another in the circumferential direction.

Abstract: A gear pairing for a helical gear unit or a spur gear unit, comprising a first gear with a first toothing portion, and a second gear with a second toothing portion, wherein the first gear has a first axis and the second gear has a second axis, which enclose a shaft angle, which is between 0 and 90°, the first toothing portion and the second toothing portion can be brought into meshing engagement and, when engaged, form an involute toothing, the materials of the first and second toothing portions are chosen so that, when engaged, a material pairing metal/plastic results, and the toothing portion made of plastic has a first helix angle and the toothing portion made of metal has a second helix angle.

Abstract: The present invention relates to an automated guide vehicle (10) for transporting objects (38) comprising a support structure (12) with an outer contour (14), a chassis (16) fastened to the support structure (12) having at least one first wheel (18) and one second wheel (20), wherein the first wheel (18) and the second wheel (20) are respectively rotatably mounted in the chassis (16) about a first axis of rotation (D1) and a second axis of rotation (D2), a drive unit (22), with which the first wheel (18) and the second wheel (20) can be driven independently from one another, a lifting mechanism (32) cooperating with the support structure (12) for lifting and lowering at least one support portion (39) which cooperates therewith to transport the objects, and a store (70) for electrical energy, which in plan view protrudes in portions beyond the outer contour (14) of the support structure (12), wherein the energy store (70) is movably fastened to the support structure (12).

Abstract: A spindle drive for the motor-driven adjustment of an adjustable element including a housing, a body connector, an adjustable element connector, a spindle nut, a spindle disposed in the housing and operatively connected to the spindle nut and the adjustable element. Either the spindle translate along a drive axis, extending in an axial direction, to move the adjustable element between an open position and a closed position, a planetary gear assembly operatively coupled to and disposed between the spindle nut and the motor, the planetary gear assembly including, a sun wheel, a planet carrier, a gear carried by the planet carrier, an annulus connected to the housing and arranged coaxially to the sun wheel, and a first frictional element non-rotatably fixed with respect to the housing and connected to either the planet gear or the planet carrier. The first frictional element brakes movement of the spindle or the spindle nut.

Abstract: A gearwheel pairing for a helical gearing, comprising a helical gear with a first toothing segment, and a worm with a second toothing segment, wherein the first toothing segment and the second toothing segment can be brought into intermeshing and form an involute toothing when intermeshed, the materials of the first and the second toothing segments are chosen such that when intermeshed there results a plastic-metal material pairing, and the toothing segment made of plastic has a first normal tooth thickness and the toothing segment made of metal has a second normal tooth thickness, wherein the ratio of the first normal tooth thickness to the second normal tooth thickness is increased by 10 to 200% with respect to a reference profile.
