APPARATUS FOR PRODUCING OPTICAL FIBER SOOT

摘要

PURPOSE:To improve the determination accuracy independent of the variation of load by forming a hinge mechanism to freely lift or lower a follower shaft of a prescribed mechanism and positioning the hinge shaft of the hinge mechanism on the line of action, etc., of the force to rotate the follower shaft. CONSTITUTION:This apparatus for producing an optical fiber soot has the following construction. A burner 11 for the synthesis of soot is placed in such a manner as to form an optical fiber soot 12 on a seed rod 1 rotating on the axis of the rod. The follower shaft 3 to rotate the seed rod 1 is rotatably supported with a lifting bracket 4 via a bearing 26. The lifting bracket 4 is supported by a supporting mechanism 5 to allow the vertical motion of the bracket and the follower shaft 3. The supporting mechanism 5 is constructed of a hinge mechanism to enable free lifting and lowering of the follower shaft 3. The hinge shaft 8 of the hinge mechanism is placed on the line of action Z of the force F to rotate the follower shaft 3.
