for every one rotation of the chain drive sprocket 208 s the wheel sprockets 2105 2125 will rotate 0 4 to 0 2 of a revolution other speed reductions are specifically contemplated since torque is inversely proportional to the shaft rotational speed torque is increased with a reduction in speed other speed reductions are specifically contemplated depending on the desired torque at the wheels and traveling speed of the machine taking loads inclines and other variables into consideration use of the offset speed reducer as disclosed herein enables the efficient use of space and provides the same torque to the wheel with less input torque supplied by the high speed electric motor the efficiency of the offset speed reducer is approximately 95 at rated load use of the offset speed reducer and electric motors enables use of high speed light weight electric motors which are smaller in diameter and output less torque than slower heavier larger motors whether they are alternating current motors or direct current motors the savings in space weight and money attained by use of the offset planetary gear reducers with high speed motors is considerable use of planetary gear reducers provides a stable transmission of power with torque amplification inversely proportional to the speed reduction the planetary gear reducers of the instant invention weigh approximately 100 pounds but can vary in weight depending on the materials used such as steel stainless steel or aluminum the gears 223 225 226 229 and the carrier 230 are made of steel or stainless steel aluminum may be used for the gearbox casing 203 203 a if extremely light weight.
