Abstract
Some belt-driven integrated-starter generators (BISGs) have twin-arm tensioners mounted directly to the BISG. Because the distance between the tensioner and the BISG pulley is quite short, any stack up tolerance leads to relatively high misalignment, which, in turn, leads to belt wear and noise. To minimize misalignment, a process is disclosed to machine the tensioner pulley bearing seats on the tensioner arms after assembly to the BISG. The BISG pulley is rotated with three probes recording the axial position change of the BISG pulley over a complete revolution. These data are used to establish a best-fit plane and the tensioner pulley bearing seats are machined to match the best-fit plane so that during operation belt twisting and shifting are minimized.
