Abstract
725,364. Change-speed gearing. ROTARY HOES. Ltd. June 17, 1953 [April 14, 1953], No. 10128/53. Class 80 (2) Two-speed epicyclic gearing comprises a sun 23 splined on the input shaft 20, a stationary annulus 31, and a planet carrier, one part 29 of which has internal teeth 36 engaged by external teeth 35 on a sleeve 24 splined on the output shaft 25 when the sleeve is in its extreme rightward position for reduced drive, the sleeve having end dogs 34 to engage end dogs 33 on the sun 23 when the sleeve is in its extreme leftward position for direct drive. The carrier is in three parts 27, 28, 29 secured together by studs 29a, the planets 30 being journaled in the parts 27, 28 by roller bearings 51, 51a. As applied to a tractor with a divided casing 11, 12 and in which the shaft 20 is driven from a main change-speed gear and is normally coupled to a final driven shaft 21 by a splined sleeve, the latter is replaced by the auxiliary two-speed gear, shaft 25 having a splined socket portion 26 engaging the splined end of shaft 21, and the annulus 31 is secured to a thin plate 32 secured between the casing parts 11, 12.
