摘要： The present invention relates to a tension roller assembly configured for tensioning a belt of a belt drive, the tension roller assembly comprising: - a tension roller, - a pivotable support arm, - a tension arm comprising a compression spring configured to press the tension roller against the belt, wherein the spring extends between a first spring stop and a second spring stop and is maintained under compression, - a mounting plate, - an overcenter assembly connected to a second end of the tension arm, the second end being opposite to the first end, wherein the overcenter assembly connects the tension arm to the mounting plate, the overcenter assembly being configured to make a pivoting movement over a pivot trajectory between: a) an engaged position which is associated with an engaged state of the tension roller assembly, and b) a disengaged position which is associated with a disengaged state of the tension roller assembly, wherein the overcenter assembly further has a center position, wherein the tension arm comprises a rod which extends from the overcenter assembly to the support arm and through the rod guide, wherein the trajectory of the overcenter assembly between the center position and the disengaged position is divided in: a) a tensioned section, and b) a free-moving section in which the spring does not exert any force on the overcenter assembly.

摘要： An agricultural harvester (10) has a header and feeder drive system (70) including a forward belt drive arrangement (82, 182) and a reverse belt drive arrangement (84, 184). The forward belt drive arrangement (82, 182) includes a forward drive belt (86, 186) and a forward belt drive tensioner (106, 206) operated by an actuator (104, 204). The reverse belt drive arrangement (84, 184) includes a reversing motor (100, 200) and a reverse drive belt (96, 196) selectively engaged with the feeder drive system (70) by operation of the same actuator (104, 204).

摘要： The present invention relates to a tension roller assembly configured for tensioning a belt of a belt drive, the tension roller assembly comprising:
- a tension roller,
- a pivotable support arm,
- a tension arm comprising a compression spring configured to press the tension roller against the belt, wherein the spring extends between a first spring stop and a second spring stop and is maintained under compression,
- a mounting plate,
- an overcenter assembly connected to a second end of the tension arm, the second end being opposite to the first end, wherein the overcenter assembly connects the tension arm to the mounting plate, the overcenter assembly being configured to make a pivoting movement over a pivot trajectory between:
a) an engaged position which is associated with an engaged state of the tension roller assembly, and
b) a disengaged position which is associated with a disengaged state of the tension roller assembly,
wherein the overcenter assembly further has a center position,
wherein the tension arm comprises a rod which extends from the overcenter assembly to the support arm and through the rod guide,
wherein the trajectory of the overcenter assembly between the center position and the disengaged position is divided in:
a) a tensioned section, and
b) a free-moving section in which the spring does not exert any force on the overcenter assembly.摘要翻译： 本发明涉及一种构造成用于张紧皮带传动带的张力辊组件，张紧辊组件包括：张紧辊， - 可枢转支撑臂， - 张力臂，包括压缩弹簧，该压缩弹簧构造成将张紧辊 其中所述弹簧在第一弹簧止动件和第二弹簧止挡件之间延伸并且被保持在压缩下， - 安装板， - 连接到所述张力臂的第二端的中心组件，所述第二端与所述第二弹簧止动件 第一端，其中所述过中心组件将所述张力臂连接到所述安装板，所述中心组件构造成在枢转轨迹之间进行枢转运动，所述枢转轨迹在：a）与所述张紧辊组件的接合状态相关联的接合位置， 以及b）与张紧辊组件的脱离状态相关联的脱离位置，其中所述过中心组件还具有中心定位 其中所述张力臂包括从所述中心组件延伸到所述支撑臂并穿过所述杆引导件的杆，其中所述中心位置和所述脱离位置之间的所述过中心组件的轨迹被分为：a）张紧部分， 和b）自由移动部分，其中弹簧不对过中心组件施加任何力。
