ROTARY CUTTERBAR GEAR HOUSING HAVING SUPPORT FOR PINION GEAR

摘要

The pinion gears of a rotary cutterbar equipped with a parallel-series arrangement of idler gears and pinion gears includes a pinion gear support p ad formed integrally with the bottom wall of the gear housing and located in close relationship to a bottom surface of the pinion gear so as to prevent the latter from moving, once bearing wear or loosening of mounting hardware has occurred, to the extent that rolling elements of a bearing arrangement supporting the pinion drive shaft are permitted to fall out into the gear housing and cause additional damage to the gearing located in the housing.
