Problems solved by technology

[0066] The planet wheels are supported by needle bearings to keep the plates apart from each other, which will inevitably lead to wear
[0067] In addition, such a solution is completely unsuitable for helical gear teeth

Embodiment Construction

[0103] figure 1 The planet carrier 1 shown in is a cage-type planet carrier and is part of an epicyclic gear system 2 .

[0104] Furthermore, the epicyclic gear system consists of the following components: 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 , which is rotatably mounted on the planetary shaft 8 of the planetary carrier 1 ; and the sun gear 9 , which is mounted to the output shaft 10 .

[0105] 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.

[0106] In this known cage planet carrier 1 , the planet wheels 6 are arranged between the two walls 11 and 12 of the planet carrier 1 .

[0107] In addition, the walls 11 and 12 support the planet shafts 8 on eith...

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 the cage type, and where at least two separate planetary- wheels are mounted on each planetary shaft, each wheel of which being supported by at least one double-row tapered roller bearing, the outermost bearing ring of each double- row tapered roller bearing being 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 each 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 requirements and subjected to extremely high loads, such as wind turbines, gears with helical teeth are often used, since such gears with helical teeth have the ability to achieve the required nomi...
