Abstract: A gear rim carrier part for a two- or multi-component gearwheel includes an annular section which revolves around an axis of rotation in the circumferential direction, a gear rim arranged radially on the outside of the annular section, and a projection which extends radially inwards from the annular section and has a radially inner free end, or the gear rim carrier part includes an annular section which revolves around an axis of rotation in the circumferential direction, a gear rim arranged radially on the inside of the annular section, and a projection which extends radially outwards from the annular section and has a radially outer free end. The projection has a first width at the radially inner free end thereof or at the radially outer free end thereof and has a second width at the opposite end thereof at the transition to the annular section.

Abstract: A drive wheel (10; 100) wherein the drive wheel (10; 100) is formed by an injection-molding process, and has a longitudinal axis (11; 108), having a hub region (12; 102) with a hub opening (13; 102), having an annular toothed-rim region (17; 106) with a radially outwardly projecting toothing (18; 105), having a substantially disk-like intermediate region (15; 112) which is arranged radially between the hub region (12; 102) and the toothed-rim region (17; 106), wherein the drive wheel (10; 100) has two bearing points (31, 32), arranged concentrically with the longitudinal axis (11; 108), for radial mounting and two bearing points (33, 34; 121, 122), for axial mounting, and wherein the hub region (12; 102) has an extension (14; 103) that protrudes from the plane of the intermediate region (15; 112) in the direction of the longitudinal axis (11; 108).

Abstract: The invention involves a gearbox, especially for adjustment devices in motor vehicles, with a plastic worm drive. The invention provides that the worm drive has an encircling, circular flat contact surface perpendicular to the worm axle and a number of removal pockets in the form of recesses that are interposed axially between contact surface and the worm axle and at the same time arranged in a level recessed to the level of contact surface, whereby an encircling bevel is formed in the transition area from level of removal pockets to the level of the circular contact surface.

Abstract: The invention involves a gearbox 1, especially for adjustment devices in motor vehicles, with a plastic worm drive 10. The invention provides that the worm drive 10 has an encircling, circular flat contact surface 27 perpendicular to the worm axle and a number of removal pockets 22 in the form of recesses that are interposed axially between contact surface 27 and the worm axle and at the same time arranged in a level 29 recessed to the level of contact surface 27, whereby an encircling bevel 23 is formed in the transition area from level 29 of removal pockets 22 to the level of the circular contact surface 27.

Abstract: The invention relates to a gear composed of an injection-molded material, comprising an internal gate region and an external toothed ring with teeth, wherein each tooth has an external tooth crest and two lateral tooth base segments, at least one locating hole for a driver element engaging from the side, and a weld line of the injection-molded material, wherein the weld line runs from an external wall of the locating hole to the outer circumference of the gear, wherein the weld line runs through the tooth crest of one of the teeth to the outer peripheral surface of the tooth. In addition, an injection-molding method is proposed for the injection molding of such a gear. Due to the path of the weld line through the gear body to the periphery of the tooth, tensile stresses are distributed along a greater distance than is the case in a conventional gear.
