  • Assembling process for mounting a rolling bearing on a gear shaft, and gear assembly obtainable by such a process
    Patent number: 10738874
    Abstract: A rolling bearing is mounted on a gear shaft, which extends along an axis and carries a first and a second toothing axially separated from each other by a cylindrical portion of the gear shaft. Such a cylindrical portion has an outer diameter smaller than that of the first toothing. The bearing is provided with rolling bodies, a cage with seats engageable by the rolling bodies, and an outer ring defining an outer rolling path for the rolling bodies. During assembly, the cage is fitted around the first toothing and axially displaced towards the second toothing until it is arranged around the cylindrical portion. In this step, the tenons of the cage pass in the slots between the teeth of the first toothing. Subsequently, the rolling bodies are radially inserted in the respective seats so as to be arranged against the cylindrical portion.
