PURPOSE:To enable the continuous regulation of a feeding quantity and a feeding speed from a high speed drive to a micro feeding by connecting one end of a driving shaft supported by a bearing with the other end to a sliding material, and locating a rotary roller having a rotary shaft inclined in the axial direction so as to contact to the peripheral surface of the driving shaft. CONSTITUTION:A motor 12 is rotated so that a rotary roller 7 is inclined with the inclination angle against a driving shaft 4. When the roller 7 is rotated by a motor 9 under this condition, the shaft 4 is rotated, but the shaft 4 is simultaneously moved in the axial direction because the roller 7 is inclined with the angle. The movement of the shaft 4 in the axial direction is transmitted to a sliding material 2 by a coupling part 3 to enable the reciprocating motion of the sliding material 2 on a guide shaft 1. When the angle alpha against the roller 7 is enlarged, the moving quantity of the shaft 4 is increased to enable a high speed drive. When the angle alpha is conversely made small, micro feeding is enabled. |
