COMPONENT OF TRACTION DEVICE, METHOD FOR MANUFACTURING IT AND TRACTION DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a diaphragm implement for a transportable traction device for curing by pulling a neck part and/or a lumber part.

SOLUTION: A process is provided for controlling a corrugated diaphragm adapted for use in the traction device in order to impart a spring force. The process includes obtaining a neutral state of the corrugated diaphragm with a length of predetermined size. The process further includes heating the corrugated diaphragm at a predetermined temperature and time to reduce the overall length of the corrugated diaphragm and increase an inner and an outer diameter of the corrugated diaphragm. The process further includes having the corrugated diaphragm installed on the traction device at a length greater than the reduced overall length and less than the neutral state.
