Abstract
Wear resistant centrifuge tile assemblies include a backing portion and a wear-resistant tile. Wear resistant centrifuge tile assemblies are provided with self-fixturing features to provide a desired mounting position and to restrict movement of the wear-resistant tile with respect to the backing plate during bonding. The self-fixturing features provide the ability to perform repeatable and consistent bonding of the wear-resistant tile to the backing plate. The bonding of the wear-resistant tile to the backing plate can be performed with a braze material.
Claims21
A centrifuge tile assembly comprising:
- a backing plate comprising a generally planar top seating face extending from a front edge of the backing plate toward a vertical seating face of a rear mounting shoulder of the backing plate;
- and
- a wear-resistant tile comprising a front edge, a distal-most rear seating edge opposite the front edge at a peripheral edge of the wear-resistant tile, first and second sides, a continuous and uninterrupted top surface and a generally planar bottom seating face,
- wherein the backing plate and the wear-resistant tile define an X-axis parallel with a plane of the generally planar top seating face of the backing plate, parallel with a plane of the generally planar bottom seating face of the wear-resistant tile, and extending parallel to the distal-most rear seating edge of the wear-resistant tile, and a Y-axis parallel with the plane of the generally planar top seating face of the backing plate, parallel with a plane of the generally planar bottom seating face of the wear-resistant tile, and extending normal to the distal-most rear seating edge of the wear-resistant tile, and wherein at least one protrusion extending from the vertical seating face of the backing plate engages at least one opposing recess recessed from the distal-most rear seating edge of the wear-resistant tile to thereby restrict relative movement between the backing plate and the wear-resistant tile in the X-axis direction and the Y-axis direction.
A centrifuge tile assembly comprising:
- a backing plate comprising a generally planar top seating face extending from a front edge of the backing plate toward a rear mounting shoulder of the backing plate, a retaining groove recessed into and below the generally planar top seating face, and a vertical seating face on the rear mounting shoulder extending from the retaining groove below the generally planar top seating face and normal to the generally planar top seating face of the backing plate;
- a wear-resistant tile comprising a top surface, a front edge, a rear seating edge, first and second sides and a generally planar bottom seating face, the generally planar bottom seating face comprising at least one alignment tab extending from the generally planar bottom seating face and structured and arranged to be received within the retaining groove of the backing plate;
- and
- a first bonding layer between the generally planar top seating face of the backing plate and the generally planar bottom seating face of the wear-resistant tile, and a second bonding layer between the vertical seating face of the backing plate and the rear seating edge of the wear-resistant tile.
A backing plate for a centrifuge tile assembly comprising:
- a generally planar top seating face extending from a front edge of the backing plate toward a rear mounting shoulder of the backing plate, a retaining groove recessed in the generally planar top seating face, a vertical seating face on the rear mounting shoulder extending from the retaining groove below the generally planar top seating face, and a semicircular alignment protrusion integrally formed with the vertical seating face and extending from the retaining groove below the generally planar top seating face, wherein the retaining groove comprises a first side transitioning into the generally planar top seating face and a second side transitioning into the vertical seating face.
A wear-resistant tile for a centrifuge tile assembly comprising:
- a generally planar top surface, a front edge, a rear seating edge comprising a generally planar portion, first and second sides and a generally planar bottom seating face, wherein the generally planar bottom seating face comprises at least one alignment tab extending from the generally planar bottom seating face structured and arranged to be received within a recessed retaining groove of a backing plate, and an alignment notch recessed from the rear seating edge structured and arranged to receive an alignment protrusion of the backing plate.
