摘要
In one aspect, a tensioner for adjusting belt tension is provided, the tensioner including first and second tensioner arms having first and second pulleys, respectively. The first and second pulleys are configured to engage with the first and second belt spans and are biased toward the first and second free arms, respectively. The second tensioner arm stopper is positioned to limit the movement of the second tensioner arm in the direction opposite to the second free arm direction. The second tensioner arm stopper is configured so that, in use, the second tensioner pulley engages the endless drive member, while the second tensioner arm stopper is engaged with the second tensioner arm stopper through the first selected range of operation. Positioned to engage. [Selection] Figure 1
