Abstract
A differential assembly for a work machine is disclosed. The differential assembly includes a differential enclosure having a side wall and a shaft extending from the side wall. The differential assembly also includes a drive gear having a gear bore defined therein. The drive gear is positioned relative to the shaft such that the shaft extends into the gear bore. The differential assembly further includes a gear shaft extending from the drive gear. The gear shaft has a differential axle cavity defined therein. The differential assembly also includes a differential axle positioned within the differential axle cavity. The differential assembly further includes a forward bearing assembly positioned within the gear bore such that the forward bearing assembly is interposed between a wall segment of the gear bore and the shaft, whereby the drive gear is capable of rotating relative to the differential enclosure. The forward bearing assembly includes (i) a forward cup, (ii) a forward cone, and (iii) a number of forward rollers interposed between the forward cup and the forward cone. The forward cup is secured to the drive gear such that no relative rotational movement occurs therebetween. The forward cone is secured to the shaft such that no relative rotational movement occurs therebetween.
