Patent ID: 8776915

Claim:
A locking clutch to selectively transmit torque from a stator of a downhole tool to a rotor of the downhole tool, the clutch comprising: at least one locking pawl disposed radially between the rotor and the stator and configured to engage at least one recess formed in an outer periphery of the rotor, wherein the at least one locking pawl comprises a load path, two pivot axes, and a mass center; and a biasing mechanism configured to bias the at least one locking pawl into an engaged position; wherein the at least one locking pawl transmits force from the stator to the rotor along the load path when in the engaged position; and wherein centrifugal force urges the at least one locking pawl into a disengaged position when the rotor is rotated about one of the two pivot axes above a disengagement speed.
