Abstract:
A method for molding a sleeve for a cylindrical bearing which permits the bearing to be loaded into the sleeve and turned to a position in which the bearing is retained in the sleeve, the bearing having a height and an outer diameter greater than said height, said sleeve includinga top; a bottom opposed to and spaced apart from said top; an elongate opening formed in said top to receive said bearing, bounded by ends (207, 208) and sides (215, 216), and having a length and a width less than said length, said width being greater than said height of said bearing but less than said outer diameter of said bearing; an opening formed in said bottom and bounded by a first pair of spaced apart opposing edges, and a second pair of spaced apart opposing edges bounding and spaced further apart than said first pair of opposing edges; a first pair of opposing spaced apart side walls (202, 203); and, a second pair of opposing spaced apart side walls (205, 225), said method comprising the steps of(a) providing a mold having a top and a bottom and a mold opening extending through said top and bottom; (b) providing a first mold insert insertible through said bottom into said mold opening to form said first pair of opposed spaced apart side walls when molding material is inserted in said mold to form said sleeve; (c) providing a second mold insert insertible through said top into said opening adjacent said first mold insert to form said second pair of opposing side walls when molding material is inserted in said mold to form said sleeve; said second mold insert including arms withdrawn through said opening in said bottom of said sleeve formed when molding material is inserted in said mold.
