Abstract
An improved bearing mount sleeve and method of making same. The sleeve has a radial flange and body portion projecting therefrom. First and second shoulders in the body portion seat large and small bearings respectively. Crush ribs apply radial preloading and wave washers apply axial preloading. The sleeve is located by tabs on its flange and a locating element projecting from the end opposite the flange A series of drawing steps result in the sleeve form and piercing and forming steps complete the sleeve at economic advantage.
Claims18
A deep drawn metal stamping in the configuration of a bearing mounting sleeve, said sleeve comprising a radially extending flange at one end, a hollow cylindrical sleeve body portion integral with the flange projecting axially therefrom and a radially inwardly extending portion integral with the body portion at an end opposite the radial flange, and at least one bearing locating shoulder formed in the body portion and facing toward the flange end, said shoulder extending radially inwardly from the inner wall of the body portion and around at least a substantial part of said inner wall so as to engage and axially locate one end of a bearing mounted within the sleeve.
A method for making a deep drawn metal stamping in the form of a bearing mounting sleeve;
- the method comprising providing a flat sheet metal blank, forming a flanged cup from the blank in the approximate configuration of the bearing sleeve progressively in a series of drawing operations, and forming a shoulder facing the flange in the course of at least one of said drawing operations, the shoulder projecting radially inwardly from the inner wall of the cup and extending around a substantial portion of the cup wall so as to engage and axially locate a bearing mounted within the cup.
A method for making a deep drawn metal stamping in the form of a bearing mounting sleeve wherein first and second axially spaced shoulders are formed during the cup drawing operation, each shoulder being adapted to engage and axially locate a bearing disposed within the sleeve.
