Planetary Gear, Wind Generator Comprising A Planetary Gear And Use Of A Planetary Gear

摘要

A planetary gear has a driving or driven wheel engaging a transmission stage having first planet gears, which are coupled to a corresponding number of second planet gears being axially displaced with respect to the first planet gears. The second planet gears engage gears of at least one sun wheel coupled to a driven or driving shaft. The second planet gears are divided into a first subset and a second subset, which are arranged in two separate planes spaced from each other in an axial direction. The first planet gears of the first subset are coupled to their corresponding second planet gears using first shafts and the first planet gears of the second subset are coupled to their corresponding second planet gears using second shafts. The first shafts have a first length and the second shafts have a second length that differs from the first length.

1. A planetary gear comprising:
a driving or driven wheel engaging a transmission stage having first planet gears, which are coupled to a corresponding number of second planet gears being axially displaced with respect to the first planet gears;
wherein the second planet gears engage gears of at least one sun wheel coupled to a driven or driving shaft;wherein the second planet gears are divided into a first subset and a second subset of gears, which are arranged in two separate planes being spaced from each other in an axial direction; andwherein the first planet gears of the first subset are coupled to their corresponding second planet gears using first shafts and the first planet gears of the second subset are coupled to their corresponding second planet gears using second shafts, wherein the first shafts have a first length and the second shafts have a second length, and wherein the first length differs from the second length.
