Abstract

PURPOSE:To automatically forwardly fast and slow feed backwardly, fast feed and stop a nut without gears in a feeding transmission by employing a one-way clutch and engaging or disengaging two clutches. CONSTITUTION:The normal rotation of a motor 2 is transmitted through a pinion 3, a gear 4 and an eccentric drum 5 from a clutch 15 to a shaft 16 to rotate the screw of an output shaft at high speed, thereby fast feeding forwardly a nut 17. Then, the clutch 15 is engaged or disengaged by an electric command to reciprocate a connecting rod 6. Thus, a lever 8 is rocked thorugh a pin 7, an arm 13 is rocked via the rod 11, and an inner ring is driven only in one direction by a one-way clutch 14. Thus, the shaft 16 is rotated at low speed through the clutch 15 to forwardly feed the nut 17 at low speed. When the nut 17 is thus fed to its forward end, the clutch 15 is operated and the motor is reversely rotated to backwardly fast feed the nut 17. Thus, the nut 17 is stopped at its backward end.
