Abstract
376,535. Change - speed gearing. RILEY, P., Riley Engine Co., Aldbourne Road, Coventry. Aug. 27, 1931, No. 24103. [Class 80 (ii).] Change-speed gearing with aligned driving and driven shafts 1, 3 and a layshaft 13 comprises an outer key 6 upon an inner key or dog 5 fast on the shaft 3. Where straight spur gearing is used, both keys are straight, but the invention is described in an arrangement with single-helical gears in which the key 6 is helical to balance the end thrusts on a sliding helical gear 8 or double gear 8, 16. The gear 8 transmitting power through the key 6 slides over a double-ended clutch sleeve 2, which engages the key 5 by means of a slot 4. When the sleeve 2 is slid to the left, the shaft 3 is driven directly through a clutch 10, the sleeve 2, and the keys 5. Movement of the sleeve 2 to the right clutches at 14 a loose gear 12<1> to the shaft 3, so that the drive is through a train 11, 11<1>, 12, 121. The end thrusts on the layshaft 13 are opposed and balance. With the sleeve 2 in mid position, other two speeds are effected by sliding the double gear 8, 16 to left and right into mesh with gears 17, 15 on the layshaft. The end thrusts on the double gear, and on the lay shaft are again substantially balanced. For reversed driving, a helical gear 18 on the layshaft drives a helical gear 19 fast on a reversing shaft 20, Fig. 3, which carries helical splines 21 on which a helical pinion 22 is slidable into mesh with the gear 8. The end thrusts on the layshaft 13 are opposed and so are those on the pinion 22, but the end thrusts on the shaft 20 are not opposed. Specification 257,413, [Class 80 (ii), Gearing, Variable-speed &c.], is referred to.
