Transmission with a planetary differential in the manner of a wild haber-novikov-spur gear

摘要

The present invention relates to a transmission with a summing stage (20), which can be formed as an additional planetary stage, which is connected to a planetary gear, wherein the planetary gear with at least two planetary stages (20, 30, 40) is provided, of which each planetary phase (20, 30, 40) are each composed of at least one set of planetary gears (3, 4, 14) and a sun wheel (8, 9, 15) is formed, wherein in the planetary gear wheels (3, 4 ‘ ‘ ‘, 8, 9, 14, 15 ‘ ‘ ‘) in meshing engagement with one another in such a way that, in each of the tooth engagements of at least a first tooth (21) to one of first teeth (21), first toothing (22) into a tooth space (23) of a second teeth (27) of the second toothing (24) engages in a form-fitting manner and in this case, the first tooth (21) with a first tooth flank (25) is at least a second tooth flank (26) of the tooth gap (23) on a side limiting second tooth (27) on the second toothing (24) in at least one contact (28), and the first teeth (21) of the first toothing (22) is a cross section through the gear teeth (21, 24) which in the tooth engagement tooth (29) which is concavely curved and the second teeth (27) of the second toothing (24) in the same cross section of a convexly arched tooth (31), in addition in such a way that the contacting tooth flanks (25, 26) of the first tooth (21) and of the second tooth (27), at least in the contact (28) in the same directions are curved, whereby further the planets (3, 4, 14) about pin axes (5, 7) bearing sections of a planet carrier (6) are arranged to be rotatable, wherein all of the pin axes (5, 7) have the same radial distance from a main axis (2) by the sunshade (8, 9) to enable the of the planet carrier (6) is rotatably mounted.
