Abstract

A spindle assembly that includes an upper bearing 1 and lower bearing 4 is assembled by the use of an adhesive cement, that is placed between the outer diameter of the sleeve 2, and the bore of the base 3. As the nut 6 is tightened in order to clamp the inner races of the bearings on the spindle 7, the preload spring 8 exerts a force between the outer races of the bearings. This spring force will cause the bearings to assume a natural alignment between the inner and outer raceways.

Spindle Assembly

A spindle assembly that includes an upper bearing 1 and lower bearing 4 is assembled by the use of an adhesive cement, that is placed between the outer diameter of the sleeve 2, and the bore of the base 3. As the nut 6 is tightened in order to clamp the inner races of the bearings on the spindle 7, the preload spring 8 exerts a force between the outer races of the bearings. This spring force will cause the bearings to assume a natural alignment between the inner and outer raceways.

Clearance that is provided between the outside diameter of the upper bearing 1 and the bearing bore of the base 3, in conjunction with the lateral freedom of the unsecured lower bearing housing 4, ensures that the natural alignment will not be affected during assembly, when locating plane AA parallel to plane BB, and maintaining the dimension X. After securing the lower bearing housing 4 with screws 5 and after the cement has hardened, the tooling may be removed.
