A self aligning gear set for maintaining optimal meshing contact between a driving gear and a driven gear that compensates for shaft deflection under a range o f loads and when an industrial double helical gear set that has a pair of helical shaft gears meshing with a pair of helical flexible bull gears and when the gear set is operating under a lo ad the shaft gears have their axial force vectors directed away from the shaft ends and the flexible helical bull gears have their axial force vectors directed toward each other such that th e shaft and bull gears remain in substantial alignment during load operation of the gear set. The bull gears preferably have a hub; an annular web positioned about said hub; and a ring gear replaceably attached to the outer circumference of said annular web.
