摘要： A first drive cam groove extends from a drive cam specific position to one side in a circumferential direction. A second drive cam groove extends from the drive cam specific position to the other side in the circumferential direction, and an inclination angle of a groove bottom with respect to one end surface of the drive cam main body is larger than that of the first drive cam groove. A first driven cam groove extends from a driven cam specific position to one side in a circumferential direction. A second driven cam groove extends from the driven cam specific position to the other side in the circumferential direction, and an inclination angle of a groove bottom with respect to one end surface of the driven cam main body is larger than that of the first driven cam groove.

摘要： An electrical submersible well pump assembly has shaft couplings. One of the couplings has a lower hub that rotates in unison with the motor shaft and an upper hub that rotates in unison with the pump shaft. A helical spring clutch engages both hubs when the motor shaft is being driven by the motor. Ceasing driving rotation of the motor shaft causes the spring clutch to disengage from the upper hub, enabling the pump shaft to rotate the upper hub without rotating the lower hub.
