Abstract
PURPOSE: To simply assemble a carriage drive and surely eliminate a backlash by interlocking a half nut which has a greater flank angle than a screw shaft, with the shaft with a play.
CONSTITUTION: When a screw shaft 11 is turned by a step motor 10, a half nut 17 engaged with the shaft makes a linear motion, which is transmitted via a leaf spring 18 to a carriage body 16, thereby shifting an entire body of a head carriage 1. As a half flank angle θN/2 of the screw shaft 11 is less than that θS/2 of the half nut 17, a thread 11b of the screw shaft may contact certain points on both the flanks of a screw groove 17b of the half nut 17, thereby absorbing a lost motion and producing no backlash.
