Abstract

Friction disks, such as rotors and stators, including keyed wear liners are disclosed. The friction disks may include a core and a replaceable wear liner coupled to each side of the core. The wear liners may include a plurality of keys which engage key notches in the core. The key notches may prevent the wear liners from rotating with respect to the core in response to a shear force, such as a force applied during braking.

First claim

What is claimed is:

1 . A rotor comprising:
a core comprising a spine and a plurality of lugs, wherein at least one lug comprises a recessed key notch; and a wear liner comprising an annular ring having a wear surface and a mating surface, wherein the mating surface is disposed adjacent to the spine, the wear liner further comprising a rotor key, wherein the rotor key is disposed within the recessed key notch.

2 . The rotor of claim 1 , wherein the wear liner is coupled to the core by at least one of a bond and a rivet.

3 . The rotor of claim 1 , wherein a thickness of the rotor key is less than a thickness of the annular ring.

4 . The rotor of claim 1 , wherein the rotor key contacts the at least one lug to oppose a shear force applied to the wear liner.

5 . The rotor of claim 1 , wherein the core comprises a first material, the first wear liner comprises a second material, and wherein the first material is different than the second material.

6 . The rotor of claim 1 , further comprising a plurality of gaps located between the plurality of lugs, wherein the plurality of gaps are configured to align with a plurality of rotor splines.

7 . The rotor of claim 1 , further comprising a plurality of wear liners, wherein a combined thickness of the plurality of wear liners and the spine is greater than a thickness of the plurality of lugs.

8 . The rotor of claim 1 , wherein the wear liner comprises a first remanufactured wear liner coupled to a second remanufactured wear liner.
