Bracket for a rotating shaft
A bracket for a rotating shaft includes a base and a retainer assembly. The base has a mount body and a receiver, first and second tabs extending from receiver and overlapping spaced apart portions of the mount body. The retainer assembly has a first retainer and a second retainer that overlap the tabs and trap the tabs against the mount body to hold the receiver on the mount body, and the first retainer overlaps part of the second retainer and the second retainer overlaps part of the first retainer to maintain the positions of the retainers relative to the mount body and receiver.

2. The bracket of claim 1 wherein, adjacent to the second end of the first retainer, the first retainer includes a cage that extends over the first end of the second retainer.
3. The bracket of claim 1 wherein, adjacent to the second end of the second retainer, the second retainer includes a cage that extends over the first end of the first retainer.
4. The bracket of claim 1 wherein the first retainer includes a first stop surface engaged with the first tab and a second stop surface engaged with a surface of the mount body on an opposite side of the mount body from a side of the mount body that is contacted by the first tab, and wherein the first opening extends between the first stop surface and the second stop surface.
5. The bracket of claim 1 wherein the second retainer includes a first stop surface engaged with the second tab and a second stop surface engaged with a surface of the mount body on an opposite side of the mount body from a side of the mount body that is overlapped by the second tab, and wherein the second opening extends between the first stop surface and the second stop surface.
6. The bracket of claim 1 wherein the mount body has an inner surface, and the mount body has a pocket that with reference to the inner surface is concave, and wherein part of the receiver is located in the pocket with at least part of the outer surface of the receiver against a surface of the mount body in the pocket, and wherein the portions of the mount body that are overlapped by the first tab and the second tab are on opposite sides of the pocket.
7. The bracket of claim 6 wherein the inner surface of the receiver has a central axis, the receiver has a width in the axial direction, the mount body has a width in the axial direction and the first retainer includes two rails that extend between the first end of the first retainer and the second end of the first retainer, and wherein the two rails are spaced apart by a distance greater than the width of at least the part of the receiver located in the pocket and the width of the mount body at the pocket, and a portion of the receiver and mount body is located between the two rails.
8. The bracket of claim 7 wherein the second retainer includes two rails that extend between the first end of the second retainer and the second end of the second retainer, and wherein part of the receiver located in the pocket and a portion of the mount body are located between the two rails of the second retainer.
9. The bracket of claim 4 wherein the first stop surface and second stop surface are spaced apart a distance so that the first tab and adjacent portion of the mount body are closely received between the first stop surface and the second stop surface to trap the first tab against mount body.
10. The bracket of claim 1 wherein the mount body is a separate component from the receiver and the receiver is held against the mount body by the first retainer and the second retainer.
11. A shaft assembly, comprising:
a shaft arranged for rotation about an axis;
a bearing coupled to the shaft;
an isolator coupled to the bearing; and
a bracket coupled to the isolator, the bracket including:
a base having a mount body and a receiver, the receiver having a circumferentially extending inner surface and an outer surface, a first tab extending from the outer surface to a first free end spaced from the outer surface, and a second tab extending from the outer surface to a second free end spaced from the outer surface, wherein the first tab and second tab overlap spaced apart portions of the mount body; and
a retainer assembly having a first retainer and a second retainer, the first retainer having a first end including a first end with a first opening through which the first tab and part of the mount body is received, the second retainer having a first end with a second opening through which the second tab and part of the mount body is received, the first retainer having a second end opposite to the first end of the first retainer and overlapping the first end of the second retainer, and the second retainer having a second end opposite to the first end of the second retainer and overlapping the first end of the first retainer.
12. The shaft assembly of claim 11 wherein the first retainer includes a first stop surface engaged with the first tab and a second stop surface engaged with a surface of the mount body on an opposite side of the mount body from a side of the mount body that is contacted by the first tab, and wherein the first opening extends between the first stop surface and the second stop surface.
13. The shaft assembly of claim 12 wherein the second retainer includes a first stop surface engaged with the second tab and a second stop surface engaged with a surface of the mount body on an opposite side of the mount body from a side of the mount body that is overlapped by the second tab, and wherein the second opening extends between the first stop surface and the second stop surface.
14. The shaft assembly of claim 11 wherein the mount body has an inner surface, and the mount body has a pocket that with reference to the inner surface is concave, and wherein part of the receiver is located in the pocket with at least part of the outer surface of the receiver against a surface of the mount body in the pocket, and wherein the portions of the mount body that are overlapped by the first tab and the second tab are on opposite sides of the pocket.
15. The shaft assembly of claim 14 wherein the inner surface of the receiver has a central axis, the receiver has a width in the axial direction, the mount body has a width in the axial direction and the first retainer includes two rails that extend between the first end of the first retainer and the second end of the first retainer, and wherein the two rails are spaced apart by a distance greater than the width of at least the part of the receiver located in the pocket and the width of the mount body at the pocket, and a portion of the receiver and mount body is located between the two rails.
