Abstract
In an aspect, a tensioner is provided for tensioning a belt on an engine, and includes a base mountable to a stationary member, and a first tensioner arm pivotably connected to the base. The first tensioner arm is biased in a first pivot direction. The tensioner includes a first bumper on one of the base and the first tensioner arm, which is engageable with a first travel limiter on the other of the base and the first tensioner arm to limit travel of the first tensioner arm in a second pivot direction, and a first pulley rotatably mounted to the first tensioner arm and positioned to engage a first section of the belt. The first bumper and the first travel limiter together have a selected first combined spring rate during engagement. The first combined spring rate increases progressively with compression between the first bumper and the first travel limiter.
