摘要： A belt tensioning device is provided for an apparatus such as a lathe which includes a centering member adapted to be attached to a workpiece and is supported for rotation about an axis. A motor is spaced from the centering member and is supported by a pivot member. A drive pulley is attached to the motor and a driven pulley is attached to the centering member. A belt is engaged between the drive pulley and the driven pulley for transmitting driving torque from the motor to the centering member. A belt tensioning device is provided for moving the pivot member between a first position wherein the belt is tensioned between the drive and driven pulleys and a second position wherein the belt is loosened between the drive and driven pulleys.
