Abstract:
A method for producing a ball nut having at least one internal bearing race with a first end and a second end, and at least one recirculating crossover passage for connecting the first end with the second end to form a continuous recirculating path for a plurality of ball bearings, comprising the steps of:forming an eyelet with a helix passage for receiving a plurality of ball bearings in a flange end;defining a portion of a crossover passage in the flange end, the crossover passage in communication with the helix passage for returning the plurality of ball bearings; andassembling two eyelets in flange-to-flange relationship with respect to one another to define at least one raceway having a single recirculating rotational path sassing through aligned portions of the crossover passage formed by the flange-to-flange relationship of the two eyelets for receiving the plurality of ball bearings.
