Sun And Planet Speed Up Gear

Abstract: A sun-and-planet speed-up gear (25) includes a low-speed-stage sun-and-planet gearing and a high-speed-stage sun-and-planet gearing, in which an input shaft is connected to a low-speed-stage ring gear, the position of a shaft of a low-speed-stage planet gear is secured, a shaft (3 a) of a low-speed-stage sun gear (3) is connected to a high-speed-stage carrier (12), and an output shaft is connected to a high-speed-stage sun gear. In order to automatically center the low-speed-stage sun gear to prevent damage to gears and a bearing, a flange (20) formed at a tip of the shaft (3a) of the low-speed-stage sun gear (3) and a flange (16) formed at a tip of a coupling (13) that is directly attached to the high-speed-stage carrier (12) or that is formed on the high-speed-stage carrier (12) are coupled via a sleeve (14).
