| Abstract |
It is designed the tension ratio of 1 : 3 to maintain tension variation within 3% for performance improvement of pulley tensioning device for high speed operation. The plant performance test and certification test of qualified office were performed for oilless bearing with a low friction coefficient and flexible wire rope. Also, it has been performed the running test, visual inspection and certification of qualified office to secure the reliability for high speed operation for 1 year. It is proved that applied the developed tensioning device for high speed operation section. |
