Abstract
A transmission apparatus includes a large number of selectable gear ratios. The transmission apparatus includes first and second primary gears mounted on rotatable shafts having offset axes of rotation. A plurality of pairs of secondary gears, each including first and second secondary gears, selectively engage the first and second primary gears. The first and second secondary gears of one of the pairs of secondary gears are selectively coupled together and engage the first and second primary gears to transmit power from a power source at a predetermined gear ratio to drive a load.
