| 摘要 | An example drill bit includes a bit body defining at least one pocket, and a support arm attachable to the bit body at the at least one pocket and including a coupling that extends from the support arm. A roller cone defines a cavity for receiving the coupling to rotatably mount the roller cone on the coupling. A direct drive electrical power generator is positioned within the coupling and is operatively coupled to the roller cone such that rotation of the roller cone correspondingly rotates a portion of the direct drive electrical power generator to generate electrical power. | ||||||
