ABSTRACT:
An engine system with a gear train to provide engine timing is disclosed. A technique to minimize backlash and noise caused by the gear train is included. An anti-backlash gear assembly useful to reduce backlash in the gear train is also disclosed. One disclosed gear assembly has at least two gear wheels with the circular thickness of the teeth of one gear wheel being less than the circular thickness of the other gear wheel. A gear assembly is also disclosed that has a bias torque of at least about 100 foot-pounds. A device carried on an anti-lash gear assembly to generally align teeth of the assembly for installation is also provided.
