A device and method for shifting the operating speed of a machine while under load. The machine includes a casing, an input and output shaft. The device includes a clutch mechanism, a primary carrier, a cluster gear, a ring gear, a first and second gear. The clutch mechanism is operably associated with the input shaft. The primary carrier is operably coupled to rotate the output shaft. The cluster gear is rotatably coupled to the primary carrier. The first gear is rotatably mounted within the casing and second gear is rotatably mounted on the first gear. The first and second gear are in mesh with the cluster gear. The cluster gear is adapted to rotate around the first and second gears on primary carrier when one of the first gear and the second gear is engaged thereby rotating the output shaft at the operating speed corresponding to the engaged gear.

Power-shiftable compound planetary transmission

A ring assembly for retaining a roller bearing and shaft. A split ring fits in a groove in the shaft and is surrounded by a lock ring to secure it in the groove. The split ring has a beveled surface which the lock ring acts against to force the split ring into the groove as the lock ring is pressed onto the split ring. An inclined surface on the split ring interacts with a ramp surface bounding the groove to press the split ring against the bearing as it moves into the groove. This applies a preload thrust to the bearing.
