Abstract
PURPOSE: To cut a high precision screw and obtain high transmission efficiency by a method wherein the rotating power of a main spindle is transmitted intermittently in a manner that a cam shaft holds a constant relation with the main spindle.
CONSTITUTION: An automatic screw cutting lathe body 6 provides a main spindle 5 which mounts a chuck 2 to bear a work 1 on one end and a main spindle pulley 4 to receive the power from a motor on the other. A follower spindle 7 is equipped near this spindle 5 and two spur gear cylinders Aa around a shaft 7 on which a large and a small spur gear 8, 8' are provided fixedly are arranged in parallel to the shaft 7, in a free state, through a bearing 9. Two spur gear cylinders Bb around the parallel shaft 12 on which a large and a small spur gear 13, 13' are provided fixedly in the same way as the shaft 7 are arranged in parallel to the shaft 12, in a free state, through a bearing 14. It is possible to cut high precision screws owing to such construction of reduction gears and obtain high transmission efficiency by spur gears.
