Abstract

A product and method for assembling multiple components using an interference fit. An assembled product includes a first component, with a second component configured to mate with the first component so that the second component is removable from the first component for a positional adjustment. A third component is configured to mate with the first component and to be engaged therewith by a first interference fit. The first interference fit is configured to impart a resultant reaction in the first component that creates a second interference fit between the first and second components.

Claims

1. An assembled product comprising:

a first component;

a second component configured to mate with the first component and to be removable from the first component for a positional adjustment; and

a third component configured to mate with the first component and to be engaged therewith by a first interference fit, wherein the first interference fit is configured to impart a resultant reaction in the first component that creates a second interference fit between the first and second components;

wherein the first component defines an opening, the second component is disposed around the first component, and the third component is a spindle received in the opening to impart the resultant reaction toward the second component.

2. The product of claim 1 comprising a fourth component located at a defined positional setting relative to the second component, wherein the positional adjustment is configured to achieve the defined positional setting.

3. The product of claim 2 comprising a shim configured to provide the positional adjustment.

4. The product of claim 2 wherein the second and fourth components are configured to be preloaded as a result of the defined positional setting.

5. The product of claim 2 wherein the second and fourth components are configured with a clearance between each other as a result of the defined positional setting.

6. The product of claim 5 wherein the second and fourth components each comprise a bearing.

7. The product of claim 1 wherein the first, second and third components are configured to not rotate.

8. A method of assembling multiple components comprising:

mating a first component configured as an opening with a second component so that the second component is around the first component and removable from the first component;

inserting a third component configured as a spindle in the opening of the first component;

engaging the first and third components together by a first interference fit;

imparting, by the first interference fit, a resultant reaction in the first component creating a second interference fit between the first and second components and imparting the resultant reaction toward the second component.

9. The method of claim 8 comprising:

locating a fourth component at a defined positional setting relative to the second component; and

making a positional adjustment of the second component to achieve the defined positional setting prior to engaging the first and third components together.

10. The method of claim 9 comprising shimming the second component to make the positional adjustment.

11. The method of claim 9 comprising preloading, as a result of the defined positional setting, the second and fourth components.

12. The method of claim 9 comprising providing, as a result of the defined positional setting, a clearance between the second and fourth components.

13. The method of claim 12 comprising configuring the second and fourth components as bearings.

14. The method of claim 8 comprising assembling the first, second and third components to not rotate.

15. A method of assembling multiple components comprising:

mating a first component with a second component so that the second component is removable from the first component;

measuring a position of the second component;

removing, when the measured position is not within a defined positional setting, the second component from the first component;

adjusting the position of the second component;

mating a third component with the first component;

engaging the first and third components together by a first interference fit; and

imparting, by the first interference fit a resultant reaction in the first component creating a second interference fit between the first and second components;

wherein mating the first component with the second component comprises sliding a first bearing as the second component onto a carrier as the first component;

wherein measuring the position of the second component comprises measuring the position of the first bearing relative to a second bearing; and

wherein mating the third component with the first component comprises pressing a spindle as the third component into an opening in the carrier, wherein the carrier expands in reaction to pressing the spindle into the opening, forcing the carrier against the first bearing creating the second interference fit.

16. The method of claim 15 wherein adjusting the position of the second component comprises shimming the second component.
