CHAIN FOR BALL CONNECTION

摘要

PROBLEM TO BE SOLVED: To improve the operation smoothness of a chain, and reduce the contact area of a ring for separation with a ball by adequately enabling the change of the chain length according the working error or operation environment. SOLUTION: The chain for ball connection has a number of rings for separation. The each ring for separation presents a ring shape. The diameter is smaller than the diameter of the ball. Both the sides are connected to a connector of a bar shape to form the construction of a chain shape. The ball is stored between the adjoining rings for separation. Each ring for separation disposed at both the ends of the chain projects one connecting block. A contact surface opposite to with each other is prepared in the two connecting blocks respectively. The each contact surface is parallel in the radial direction of the bent curvature center of the chain. COPYRIGHT: (C)2007,JPO&INPIT
