Play-free planetary gear with divided planet gears, which by means of prestressing elements which are arranged parallel to the planetary rotation axis are prestressed

摘要

Play-free planetary gear (1) with a sun gear (2), with a ring gear (3) and with at least one into engagement with the planet wheel (4) located around a planetary rotation axis (5) is rotatably supported on a planet carrier (6) is mounted, wherein the teeth (13) of a planet gear (4) is a division plane (7), which is perpendicular to the planetary rotation axis (5) is aligned, by means of which the planet gear (4) in a first part of the planetary gear (8) and a second part of the planetary gear (9) is divided, wherein the first part of the planetary gear (8) by a substantially parallel to the planetary rotation axis (5) in the two part planetary gears (8, 9), a spring rod (10) relative to the second part of the planetary gear (9) is biased, wherein one or more to bending loaded (r), in the two part planetary gears (8, 9) and (r) spring rod / spring rods (10) around the planetary rotation axis (5) is / are arranged, whereby at least one spring rod (10) in a first recess (11) of the first part of the planet gear (9) and a second recess (12) of the second part of the planet gear (9) is arranged, wherein the first and second recess (11, 12) to the region of the parting plane (7) and wherein the first recess (11) and the second recess (12) as the of the division plane (7) is designed as a funnel-shaped hole.
