A synchronous belt drive system having: a synchronous belt with a tensile cord of high-modulus fiber such as glass, carbon, PBO, or aramid; a driver sprocket and at least one driven sprocket, at least one of which is an obround sprocket; and a tensioner having: a base having a cylindrical portion extending axially with a radially outer surface and a receiving portion, an eccentric arm pivotally engaged with the radially outer surface, a torsion spring disposed within the receiving portion, the torsion spring applying a biasing force to the eccentric arm, and a pulley journalled to the eccentric arm. Preferably, no one of the eccentric arm, pulley, or torsion spring is axially displaced along an axis A-A from the others. The obround sprocket has a toothed surface and at least one linear portion disposed between two arcuate portions having a constant radius, the linear portion having a predetermined length.

Synchronous belt drive system

A fabric for reinforcing a power transmission belt including fibers of polyarylene sulfide and a belt utilizing the fabric. The fabric may have textured or elastic core wrapped stretch yarns in the longitudinal direction. Longitudinal yarns may include PPS and textured transverse yarns include nylon. Yarns may include blends of high performance fibers and nylon or other fibers.
