<p>A belt tensioning device (10) for shifting a pulley (20) such that a belt (30) passed around the pulley (20) is tightened to a predetermined tension. The device includes a rod (34) coupled to the pulley (20), a member (50) coupled to and movable along the rod (34), and a spring (46) that exerts a reactive force against the member (50) when the member (50) is moved in a first direction along the rod (34). The device further includes a spacer (44) which engages the member to limit the advancement of the member in the first direction.</p> |
