Abstract
A wood-turning lathe includes a spindle and a drive shaft journalled to a headstock housing. A motor is mounted in the headstock housing, and includes a rotor. A torque converter includes a first wheel that co-axially surrounds the spindle and that is securely coupled to the rotor, a second wheel mounted securely on the drive shaft, and a belt trained on the first and second wheels, thereby increasing torque of the drive shaft. A speed change device includes a first pulley unit mounted on the drive shaft and defining a first belt-engaging surface, a second pulley unit mounted on the spindle and defining a second belt-engaging surface, and a non-elastic belt interconnecting the first and second pulley units and frictionally contacting the first and second belt-engaging surfaces.
