Gear transmission unit with planetary gears
Abstract:
A planetary type gear transmission unit (11) suitable for a wind turbine (10) includes sun (27), planet (25) and ring (24) gears and a planet carrier (41), the planet carrier (28) including a planet bogie plate (43) which supports and locates circumferentially spaced pairs of planet gears (25) a planetary type gear transmission unit (11) includes sun (27), planet (25) and ring gears (24) and a planet carrier(28), the planet carrier (28) including a planet bogie plate (43) which supports and locates circumferentially spaced pairs of planet gears (25), the sun (27) and ring gears (24) being each of the double helical type and each of the planet gears (47) of a pair being of the single helical type and of a helix angle opposite to that of the other planet gear (48) of the pair.
