Abstract
Official abstract text for this publication.
A method of fabricating a ball nut assembly is provided. The method includes providing a ball nut having a keyway slot. The method also includes forming a polymer pulley having an inner surface defining a bore, a cut-out formed in the inner surface, and a torque member extending radially inward from the inner surface, wherein the keyway slot is configured to receive the torque member therein.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of fabricating a ball nut assembly, the method comprising: providing a ball nut having a keyway slot; forming a polymer pulley having an inner surface defining a bore, a cut-out formed in the inner surface, and a torque member extending radially inward from the inner surface, wherein the keyway slot is configured to receive the torque member therein; inserting the polymer pulley onto the ball nut such that the torque member is at least partially within the keyway slot; and deforming a portion of the polymer pulley proximate the cut-out to define a generally flat portion of the pulley. 2. The method of claim 1 , wherein forming the polymer pulley further comprises fabricating the pulley from nylon resin. 3. The method of claim 1 , further comprising forming a groove on an end of the ball nut and inserting a retainer into the groove. 4. The method of claim 1 , further comprising forming a flange and coupling the flange to the polymer pulley.
