  • Variable speed belt driven transmission system and method
    Patent number: 4571216
    Abstract: A variable speed belt drive transmission system with a driven pulley having a movable pulley half operated to move axially with generated axial forces that decrease from where the driven pulley is closed to where the driven pulley is open, the maximum generated force being from about 100 to about 120 percent of a required pulley axial force where theoretical belt slip could occur.A method for enhancing belt life by controlling belt tension with driven pulley axial force by establishing a required driven pulley axial force that decreases from where the driven pulley is closed to where the driven pulley is open, the generated force lines being from about 100 to about 120 percent of a determined pulley axial force line where theoretical belt slip impends.
    Type: Grant
    Filed: May 31, 1985
    Date of Patent: February 18, 1986
    Assignee: The Gates Rubber Company
    Inventors: Richard F. Stieg, John P. Dolan, Wm. Spencer Worley, Goran Gerbert
