Abstract
A carriage assembly includes a housing having first and second pieces each defining a recess that has a bearing surface with raised dimples. The first and second pieces are assembled to each other such that the recesses are aligned to form a cylindrical hole. A bushing is received in the hole and has an outer surface disposed against the dimples of the first and second pieces. The dimples are deformed during assembly to secure and locate the bushing within the cylindrical hole.
Claims18
A carriage assembly comprising:
- a housing including first and second pieces each defining a recess that has a bearing surface with raised dimples, the recess of the first piece having a partition extending from the bearing surface and engaging with the bushing to restrict axial movement of the bushing within the hole, wherein the first and second pieces are assembled to each other such that the recesses are aligned to form a cylindrical hole;
- and
- a bushing received in the hole and including an outer surface disposed against the dimples of the first and second pieces.
A carriage assembly comprising:
- a first housing piece including a first surface and a first half-moon recess extending into the first surface and having a bearings surface with a first array of raised dimples;
- a second housing piece including a second surface and a second half-moon recess extending into the second surface and having a bearings surface with a second array of raised dimples, wherein the first and second housing pieces are assembled to each other with the first and second surfaces engaging and with the first and second recesses aligned to form a cylindrical hole;
- and
- a cylindrical bushing received in the hole and including an outer surface disposed against the dimples of the first and second arrays, wherein the dimples of the first and second arrays are partially deformed to create an interference fit between the dimples and the bushing.
1 more element
A method comprising:
- providing a first housing piece defining a first recess that has a bearing surface with a first set of raised dimples;
- installing a bushing into the first recess with an outer surface of the bushing disposed against the first set of raised dimples;
- assembling a second housing piece, that defines a second recess having a bearing surface with a second set of raised dimples, onto the first housing piece to assemble a housing, wherein the pieces are assembled such that the recesses are aligned to form a hole extending through the housing and such that the bushing is disposed in the second recess with the outer surface of the bushing disposed against the second set of raised dimples;
- and
- compressing the first and second pieces towards each other to deform the dimples of the first and second sets against the outer surface creating an interference fit between the dimples and the bushing.
