Method of Manufacturing Split Bearing Races
A method of manufacturing or forming a split bearing race for an angular contact roller bearing is provided. The method includes the steps of: A) forming a generally annular blank having a first annular portion, a second annular portion, and a third annular portion disposed between the first and second annular portions, the third annular portion having a thickness greater than the thickness of the first and second annular portions; B) machining at least one of the first, second, and third annular portions; and C) forming a first and second race member of the split bearing race by bifurcating the generally annular blank along the third annular portion. The method may also include the steps of: D) heat treating the generally annular blank after machining at least one of the first, second, and third annular portions; and E) finish machining the generally annular blank subsequent to the heat treating.
1 . A method of manufacturing a split bearing race for an angular contact roller bearing comprising:
forming a generally annular blank having a first annular portion, a second annular portion, and a third annular portion disposed between said first and second annular portions;
wherein said third annular portion has a thickness greater than the thickness of said first and second annular portions;
machining at least one of said first, second, and third annular portions; and
forming a first race member and a second race member of the split bearing race by bifurcating said generally annular blank along said third annular portion.
2 . The method of manufacturing a split bearing race of claim 1 , wherein the split bearing race is an inner bearing race.
3 . The method of manufacturing a split bearing race of claim 1 , wherein forming said generally annular blank includes hot rolling.
4 . The method of manufacturing a split bearing race of claim 1 , further comprising heat treating said generally annular blank after machining at least one of said first, second, and third annular portions.
5 . The method of manufacturing a split bearing race of claim 4 , further comprising finish machining said generally annular blank subsequent to said heat treating.
6 . The method of manufacturing a split bearing race of claim 5 , wherein said finish machining of said generally annular blank subsequent to said heat treating is performed by grinding.
7 . A method of manufacturing a split bearing race for an angular contact roller bearing comprising:
forming a generally annular blank having a first annular portion, a second annular portion, and a third annular portion disposed between said first and second annular portions;
wherein said third annular portion has a thickness greater than the thickness of said first and second annular portions;
wherein forming said generally annular blank includes hot rolling;
machining at least one of said first, second, and third annular portions; and
forming a first race member and a second race member of the split bearing race by bifurcating said generally annular blank along said third annular portion.
8 . The method of manufacturing a split bearing race of claim 7 , further comprising heat treating said generally annular blank after machining at least one of said first, second, and third annular portions.
9 . The method of manufacturing a split bearing race of claim 8 , further comprising finish machining said generally annular blank subsequent to said heat treating.
10 . The method of manufacturing a split bearing race of claim 9 , wherein said finish machining of said generally annular blank subsequent to said heat treating is performed by grinding.
11 . A method of manufacturing a split bearing race for an angular contact roller bearing comprising:
forming a generally annular blank having a first annular portion, a second annular portion, and a third annular portion disposed between said first and second annular portions;
wherein said third annular portion has a thickness greater than the thickness of said first and second annular portions;
wherein forming said generally annular blank includes hot rolling;
machining at least one of said first, second, and third annular portions;
heat treating said generally annular blank after machining at least one of said first, second, and third annular portions;
finish machining said generally annular blank subsequent to said heat treating by grinding said generally annular blank; and
forming a first race member and a second race member of the split bearing race by bifurcating said generally annular blank along said third annular portion.
