Abstract
A wood lathe includes a driving pulley unit disposed around a rotating inner rod, a driven pulley unit disposed around an output shaft that is used to rotate a workpiece, a V-belt unit trained on the driving and driven pulley units, and a speed-adjusting unit. When a rotary knob is rotated, amovable inner half of the driven pulley unit moves toward or away from a fixed outer half of the driven pulley unit so that the V-belt unit moves a movable outer half of the driving pulley unit away from or toward a fixed inner half of the driving pulley unit. As such, the position of the V-belt unit can be adjusted relative to the driving and driven pulley units to change the rotational speed of the output shaft.
