Composite metallic elastomeric sealing components for roller cone drill bits

Composite metallic elastomeric sealing components for roller cone drill bits

An earth boring bit has a bit body with a depending bearing pin, a cone rotatably mounted on the bearing pin, a seal gland between the cone and the bearing pin, and a seal assembly located in the seal gland. The seal assembly includes an annular metallic spring encircling the bearing pin. The spring...

description An earth boring bit has a bit body with a depending bearing pin, a cone rotatably mounted on the bearing pin, a seal gland between the cone and the bearing pin, and a seal assembly located in the seal gland. The seal assembly includes an annular metallic spring encircling the bearing pin. The spring has a geometric center line that extends in a circle around the bearing pin. The spring is elastically deformable in radial directions relative to the center line. An elastomeric layer is located on an exterior side of the spring and is biased by the spring against a surface of the seal gland.
