Patent ID: 8512192

Claim:
A lubrication device for a planetary transmission comprising a plurality of planetary gearsets ( 2 , 3 ; 2 ′, 3 ′) in which a ring gear carrier ( 12 , 12 ′), which supports a ring gear ( 11 , 11 ′) of a first planetary gearset ( 2 , 2 ′), being connected to a planetary gear carrier ( 19 , 19 ′) which supports a plurality of planetary gears ( 15 , 15 ′) of an adjacent, second planetary gearset ( 3 , 3 ′), a lubricant supply path being provided for the planetary gears ( 15 , 15 ′) of the second planetary gearset ( 3 , 3 ′), and the ring gear ( 11 , 11 ′) of the first planetary gearset ( 2 , 2 ′) being sealed relative to the ring gear carrier ( 12 , 12 ′) of the first planetary gearset ( 2 , 2 ′) and relative to the planetary gear carrier ( 19 , 19 ′) of the second planetary gearset ( 3 , 3 ′) by a sealing element that is located between the ring gear ( 11 , 11 ′) and the ring gear carrier ( 12 , 12 ′) of the first planetary gearset ( 2 , 2 ′) along a radial axis.
