Abstract
A multi-speed transmission suitable for automotive-type use employs paired helical gears. For each speed of the transmission, at least one pair of helical cut gears is mounted on an input drive shaft for engaging and mating at least one pair of helical cut gears mounted on an idler shaft. During load transmission for a given speed, the helical gear pairs on the idler shaft center themselves on the helical gear pairs on the drive shaft to balance load transmission amongst gears. The idler shaft would also have at least one pair of helical cut gears to engage and mate at least one pair of helical cut gears on a power output shaft.
