Abstract
A new type of swivel unit is suggested in order to complement weak points of the existing. This new type of Swivel unit is developed by adopting a spring type cable which has elasticity and restoring force. To minimize the troubles in the process of manufacturing during operating the new type system, strength analysis and the check of interference between parts are accomplished with CATIA. The check of rotating performance is also carried out to determine the diameter and length of spring type cable by SimDesigner motion analysis. Swivel unit used in the robot spot welding is developed with spring type cable and its usefulness in the industrial field is verified through experiments. This system has been registered for patent.
