Abstract
A torque converter stator made by injection molding of plastic material includes a metallic one-way clutch outer race which is insert molded within the stator hub. A plurality of recesses forming lubricant passages extend through the wall of a radial flange of the hub. The lubrication recess (30) is defined by a part-cylindrical outer wall (32) and a pair of planar side walls (34) spaced apart by a distance d. The juncture of the outer wall (32) and the side wall (34) is filleted to form a rounded corner (36) having a radius of curvature R1. To relieve the weld line (60) from concentration of residual stress due to post-molding shrinkage while avoiding stress concentration at the rounded corners (36), the ratio R1/d is selected to be 0.18-0.35.
