用于泥浆马达的锁紧离合器
摘要：
本发明公开了一种锁紧离合器，所述锁紧离合器选择性地将来自井下工具的定子的扭矩传递给井下工具的转子，所述锁紧离合器包括设置在转子上的至少一个锁定爪，其中至少一个锁定爪包括负载路径、至少一个枢转轴线和质心，其中至少一个锁定爪通过偏压机构被偏压到接合位置，其中至少一个锁定爪在位于接合位置时沿着负载路径将来自定子的力传递给转子，并且其中当转子超过脱离速度旋转时，离心力将至少一个锁定爪推动到脱离位置。
摘要（英）：

A locking clutch to selectively transmit torque from a stator of a downhole tool to a rotor of the downhole tool includes at least one locking pawl disposed upon the rotor, wherein the at least one locking pawl comprises a load path, at least one pivot axis, and a mass center, wherein the at least one locking pawl is biased into an engaged position by a biasing mechanism, 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 above a disengagement speed.
