Abstract
A power conveying system for use with a header of an agricultural harvester, the header having a first structural member and a second structural member being pivotally coupled to the first structural member about an axis. The power conveying system including a driving pulley, a driven pulley, an idler pulley, a flexible link and a cantilevered member. The driving pulley is coupled to the first structural member, and the driven pulley is coupled to the second structural member. The flexible link conveys power from the driving pulley to the driven pulley, and is in contact with the idler pulley. The cantilevered member is connected to the second structural member, and extends beyond the axis, where the cantilevered member is movably coupled to the idler pulley.
Claims20
An agricultural harvester, comprising:
- a chassis;
- a ground engaging transport system supporting said chassis;
- and
- a header mechanism extending from said chassis, said header mechanism including:
- a first structural member;
- a second structural member pivotally coupled to said first structural member about an axis;
- a power conveying system, having:
- a driving pulley coupled to said first structural member;
- a driven pulley coupled to said second structural member;
- an idler pulley;
- a flexible link conveying power from said driving pulley to said driven pulley, said flexible link in contact with said idler pulley;
- and
- a cantilevered member connected to said second structural member, said cantilevered member extending beyond said axis where said cantilevered member is movably coupled to said idler pulley.
A power conveying system for use with a header of an agricultural harvester, the header having a first structural member and a second structural member being pivotally coupled to the first structural member about an axis, the power conveying system comprising:
- a driving pulley coupled to the first structural member;
- a driven pulley coupled to the second structural member;
- an idler pulley;
- a flexible link conveying power from said driving pulley to said driven pulley, said flexible link in contact with said idler pulley;
- and
- a cantilevered member connected to said second structural member, said cantilevered member extending beyond said axis where said cantilevered member is movably coupled to said idler pulley.
A method of maintaining a pressure on a flexible link of a power conveying system, the power conveying system being used with a header of an agricultural harvester, the header having a first structural member and a second structural member being pivotally coupled to the first structural member about an axis, the method including the steps of:
- driving the flexible link with a driving pulley coupled to the first structural member;
- driving a driven pulley coupled to the second structural member with the flexible link, said flexible link being in contact with an idler pulley;
- and
- moving said idler pulley with a cantilevered member as the second structural member pivots about the axis, the cantilevered member being connected to the second structural member, said cantilevered member extending beyond the axis where said cantilevered member is movably coupled to said idler pulley.
