Abstract
An annular flange which can be positioned on a shaft and securely welded in place. This disclosure also contemplates the method of making an annular shaft flange. This novel flange is materially stronger than the prior art and has lower production costs.
Claims6
An annular shaft flange for attachment to a shaft extending along a longitudinal axis, the shaft flange comprising:
- a flange body having a first axial end face and a second axial end face, the first and second axial end faces being parallel and opposed, the first and second axial end faces being spaced to define an axial width of the shaft flange,
- wherein each of the first and second axial end faces has a radial width extending between an inner curved surface and an outer curved surface, the radial width being substantially larger than the axial width of the shaft flange;
- a first nest end and a second nest end formed on the flange body, the first and second nest ends being spaced apart when the annular shaft flange is in an open position;
- a hinge channel formed in the flange body to permit the flange body to flex between the open position and a closed position, the hinge channel extending radially outward from the inner curved surface a distance less than the radial width of the flange body;
- a first lip extending from the first nest end of the flange body, the first lip having a width of approximately one-half the axial width of the flange body and being spaced inwardly from the first axial end face by a first recess approximately equal to one-half the axial width of the flange body;
- and
- a second lip extending from the second nest end of the flange body, the second lip having a width of approximately one-half the axial width of the flange body and being spaced inwardly from the second axial end face by a second recess approximately equal to one-half the axial width of the flange body;
- wherein when the flange body is flexed from the open position to the closed position, the first lip is received in the second recess and overlaps the second lip such that the first and second lips can be spot welded to retain the shaft flange in the closed position.

An annular shaft flange for attachment to a shaft extending along a longitudinal axis, the shaft flange comprising:
- a first generally semi-circular flange body member and a second generally semicircular flange body member, each flange body member having a first axial end face and a second axial end face, the first and second axial end faces being parallel and opposed, the first and second end faces being spaced to define an axial width for each flange body member;
- wherein each of the axial end faces of each flange body member has a radial width extending between an inner curved surface and an outer curved surface, the radial width of each flange body member being substantially greater than its axial width;
- a first nest end and a second nest end formed on each of the flange body members;
- a first lip extending from the first nest end of each flange body member, the first lip having a width of approximately one-half the axial width of the flange body member and being spaced inward from the first axial end face by a first recess equal to approximately one-half the axial width of the flange body member;
- and
- a second lip extending from the second nest end of each flange body member, the second lip having a width of approximately one-half the axial width of the flange body member and being spaced inward from the second axial end face by a second recess equal to approximately one-half the axial width of the flange body member;
- wherein to form the complete annular shaft flange, the first lip on the first flange body member is positioned to overlap the second lip on the second flange body member and the second lip on the first flange body member is positioned to overlap the second lip on the second flange body member such that the overlapping lips on the first and second flange body members can be spot welded to join the first and second flange body members in a generally circular shape.
