摘要： A planetary gear for a planetary gearset has a gear body and a planetary gear shaft defining a planetary gear rotational axis (APR) of the planetary gear. The gear body includes a gear rim having a first number (n1) of teeth and a second number (n2) of ribs. The ribs extend between the planetary gear shaft and the gear rim, and planetary gear contact projections are arranged on the ribs and project beyond the gear rim along the planetary gear rotational axis (APR). Also disclosed is a planet carrier for such a planetary gear, including an insert for removing torque from the carrier body, which insert is connected to the first disk-shaped body. The first disk-shaped body forms a first free planet carrier face on which a number of reinforcing ribs are arranged.

摘要： 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.

摘要： 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).

摘要： 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.
