Abstract

A friction disk includes a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface, each of the multiple mortises having a different dimension at the inner diameter edge than at the outer diameter edge. The friction disk further includes a first wear liner having two wear liner segments each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon being configured to be received by a corresponding mortise of the multiple mortises to couple the wear liner segments to the friction disk core to form an annular liner.

First claim

What is claimed is:

1. A friction disk comprising:
a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface, each of the multiple mortises having a different dimension at the inner diameter edge than at the outer diameter edge; and
a first wear liner having two wear liner segments each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon being configured to be received by a corresponding mortise of the multiple mortises to couple the wear liner segments to the friction disk core to form an annular liner,
wherein each of the multiple mortises has a depth that is less than half of a thickness of the friction disk core, and
wherein each of the multiple mortises extend from the inner diameter edge of the friction disk core to the outer diameter edge of the friction disk core.

2. The friction disk of claim 1 , further comprising a second wear liner having identical features as the first wear liner, wherein the friction disk core has a second surface with second mortises being identical to the multiple mortises of the first surface, and wherein the second wear liner is configured to be coupled to the second surface of the friction disk core via the second mortises.

3. The friction disk of claim 1 , wherein the first wear liner is configured to be coupled to the friction disk core without use of fasteners.

4. The friction disk of claim 1 , wherein the multiple mortises and the tenon have complimentary dovetail shapes.

5. The friction disk of claim 1 , wherein the friction disk core is a rotor core and each of the multiple mortises has a greater dimension at the inner diameter edge than at the outer diameter edge.

6. The friction disk of claim 1 , wherein the friction disk core is a stator core and each of the multiple mortises has a greater dimension at the outer diameter edge than at the inner diameter edge.

7. The friction disk of claim 1 , wherein the friction disk core includes a first material, and the first wear liner comprises a second material that is different from the first material.

8. A friction disk comprising:
a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface, each of the multiple mortises having a different dimension at the inner diameter edge than at the outer diameter edge; and
a first wear liner having a first wear liner segment and a second wear liner segment each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon being configured to be received by a corresponding mortise of the multiple mortises to couple the first wear liner segment and the second wear liner segment to the friction disk core without use of fasteners to form an annular liner,
wherein each of the multiple mortises has a depth that is less than half of a thickness of the friction disk core, and
wherein each of the multiple mortises extend from the inner diameter edge of the friction disk core to the outer diameter edge of the friction disk core.
