Abstract
An engine system includes a frame, a prime mover, and drive-belt system. The prime mover is coupled with the frame for movement therewith. The drive-belt system includes a wheel configured to be driven by the prime mover about a rotation axis and to transmit energy to an accessory unit.
Claims18
An engine system comprising:
- a frame,
- a prime mover coupled with the frame for movement therewith, the prime mover including a crankshaft configured to rotate about a rotation axis,
- an accessory unit adapted to be powered by the prime mover, and
- a drive-belt system including a crankshaft pulley coupled with the crankshaft for rotation with the crankshaft about the rotation axis, a band coupled to the crankshaft pulley and the accessory unit, and a bias-member assembly coupled with the crankshaft pulley and with the frame,
- wherein the band applies a tension force to the crankshaft pulley in a first radial direction relative to the rotation axis and the bias-member assembly applies a counterforce to the crankshaft pulley in a second radial direction relative to the rotation axis and the second radial direction is different than the first radial direction.

An engine system comprising:
- a drive-belt system that includes:
- a crankshaft pulley configured to be coupled with a crankshaft of an engine for rotation with the crankshaft about a rotation axis and
- a bias-member assembly coupled with the crankshaft pulley, the bias-member assembly configured to apply a radial counterforce to the crankshaft pulley relative to the rotation axis.
A method comprising:
- providing a frame, a prime mover having a crankshaft configured to rotate about a rotation axis, and a drive-belt system including a wheel and a bias-member assembly,
- coupling the prime mover with the frame for movement therewith,
- coupling the wheel with the crankshaft for rotation with the crankshaft about the rotation axis, and
- coupling the bias-member assembly with the wheel and with the frame to cause the bias-member assembly to apply a first radial force to the wheel in a first direction.
