Problems solved by technology

[0068] The solution suggested in DE 0.054.280 is not at all suitable for helical teeth if the presence of one roller element per planet is not sufficient to handle the tipping moments present in the case of helical teeth

Embodiment Construction

[0089] figure 1 The planet carrier 1 shown in is a cage-type planet carrier and is part of an epicyclic gear system 2 .

[0090] Furthermore, the epicyclic gear system consists of the following: ring gear 3, which is connected to housing 5 by bolts 4; planetary gears 6, in figure 1 Only one of the planetary gears 6 is shown in , and the planetary gear 6 is rotatably mounted on the planetary shaft 8 of the planetary carrier 1 ; and the sun gear 9 is mounted to the output shaft 10 .

[0091] The planet carrier 1 of the known epicyclic gear system 2 can be used to convert the slow rotation of the planet carrier 1 to the output shaft 10 through the interaction between the planet wheels 6 and the sun gear 9 on this planet carrier 1 with the ring gear 3 fast rotation.

[0092] In this known cage planet carrier 1 , the planet wheels 6 are arranged between two walls 11 and 12 of the planet carrier 1 .

[0093] In addition, the walls 11 and 12 support the planet shafts 8 on either s...

Abstract

Planet carrier (18) of an epicyclic gear system (20) with planetary shafts (8) which are connected fixedly to the planet carrier onto which planet wheels (6) are mounted rotatably using planetary bearings, the teeth of the planetary wheels being helical or chevron teeth, the said planet carrier being of a cage type, and where at least two separate planetary wheels are placed on each planetary shaft, each wheel of which being supported by at least one double-row cylindrical bearing, where the outer bearing ring of each double-row cylindrical bearing is integrated into the planetary wheel concerned.

Description

technical field [0001] The present invention relates to a cage-type planet carrier. [0002] In particular, the invention relates to a planet carrier for an epicyclic gear system equipped with planet shafts fixedly connected to the planet carrier and on which planets are mounted in a rotatable manner via planet bearings wheel. [0003] More particularly, the invention relates to a cage-type planet carrier, the planet wheels of which are arranged between two walls of the planet carrier, wherein these walls support the planet shafts on either side of the planet wheels. [0004] In addition, the invention relates to a planet carrier for a planetary gear system comprising gears with helical or helical teeth. Background technique [0005] For planetary gear transmissions with very high demands and subjected to extremely high loads, such as wind turbines, gears with helical teeth are often used, since such gears with helical teeth are essential for achieving the required nominal...
