Abstract
Load-carrying apparatus, assemblies, and subterranean drilling systems may include a support ring with a plurality of contact elements coupled to the support ring. The plurality of contact elements may have a surface exhibiting a partially cylindrical shape.
Claims19
A load-carrying apparatus, comprising:
- an inner assembly comprising:
- an inner support ring positioned circumferentially about an inner ring axis;
- and
- a first plurality of superhard contact elements coupled to the inner support ring, each of the first plurality of superhard contact elements having a superhard contact surface, the superhard contact surface of each of the first plurality of superhard contact elements comprising a convex partial-cylindrical surface substantially centered about the inner ring axis;
- and
- an outer assembly comprising:
- an outer support ring positioned circumferentially about an outer ring axis;
- and
- a second plurality of superhard contact elements coupled to the outer support ring, each of the second plurality of superhard contact elements having a superhard contact surface;
- wherein the superhard contact surface of each of the second plurality of superhard contact elements comprises a partial-spherical surface.

A load-carrying apparatus, comprising:
- a first assembly comprising:
- a first support ring positioned circumferentially around a first ring axis;
- and
- one or more contact elements coupled to the first support ring, the one or more contact elements each having a contact surface, the contact surface of each of the one or more contact elements exhibiting a partial-cylindrical surface;
- and
- a second assembly comprising:
- a second support ring positioned circumferentially around a second ring axis;
- and
- one or more contact elements coupled to the second support ring, the one or more contact elements each having a contact surface, the contact surface of each of the one or more contact elements coupled to the second support ring opposing a respective one of the partial-cylindrical surface of the one or more contact elements coupled to the first support ring, wherein the contact surface of each of the one or more contact elements coupled to the second support ring comprises a partially spherical surface.
6 more elements
A subterranean drilling system, comprising:
- an output shaft operable to apply torque to a rotary drill tool, the output shaft operably coupled to a load-carrying apparatus, the load-carrying apparatus comprising:
- an inner assembly comprising:
- an inner support ring;
- and
- a first plurality of superhard contact elements coupled to the inner support ring, each of the first plurality of superhard contact elements having a superhard contact surface, the superhard contact surface of each of the first plurality of superhard contact elements defining a partial-cylindrical outer surface;
- and
- an outer assembly comprising:
- an outer support ring;
- and
- a second plurality of superhard contact elements coupled to the outer support ring, each of the second plurality of superhard contact elements having a superhard contact surface;
- wherein the superhard contact surface of each of the second plurality of superhard contact elements defines an inner surface substantially centered about an outer ring axis and opposing the partial-cylindrical outer surface of the inner assembly, and wherein the superhard contact surface of each of the second plurality of superhard contact elements comprises a partially spherical surface or a planar surface.
