Abstract: Systems and methods which provide motive forces with respect to various apparatuses using self-engaging/disengaging transmission configurations are described. An autonomous-state transmission may comprise a transmission unit configured to autonomously engage and disengage transmission of power from a driving input member to a driven output member without utilization of external gearing or additional mechanical feedback. Embodiments of an autonomous-state transmission may utilize various roller-ramp clutch configurations in communication with override control for disengaging the roller-ramp clutch. The override control may implement various configurations of a skidding mechanism for facilitating engaging and/or disengaging the roller-ramp clutch. According to some examples, motion of the driving input member and/or driven output member is utilized for override force detection and providing override control with respect to the autonomous-state transmission. Embodiments of an autonomous-state transmission may be bidirectionally operative to autonomously engage and disengage transmission of power from a driving input to a driven output.

Abstract: A selectable clutch with a selector is provided, in which support grooves are formed to one of an inner race and an outer race, while pocket parts are formed to the other. A resilient member is provided to bias rollers disposed between the inner race and outer race toward the pocket parts. A roller-holding surface of the support groove and a roller-holding surface of the pocket part are formed with an inclination angle such that, when the rollers are held therebetween, a force acts on the rollers in a direction to move the rollers toward the pocket parts. In the lock mode, the rollers are each held by the support groove, pocket part, and selector.

Abstract: To provide a cam clutch unit that reduces the number of machining steps and level of difficulty of cam clutch production and reduces rotation resistance caused by rollers. The cam clutch unit includes: a plurality of cams and a plurality of rollers circumferentially arranged between an inner race and an outer race that are coaxial and rotatable relative to each other; a cage ring having a plurality of pocket portions that restrict circumferential relative movements of the cams and the rollers; and an annular spring that biases the cams. The cams each have, on one axial end face, an engagement step that can engage with the spring. The cage ring has a plurality of hook portions that restrict axial movements of the annular spring.

Abstract: A free-wheel comprising a driving part and a driven part that are able to rotate about an axis of rotation, the free-wheel comprising at least one rotational connecting member arranged in a connection space, a driven connection section of the driven part surrounding a driving connection section of the driving part, the connection space being located radially, with respect to the axis of rotation, between the driving connection section and the driven connection section. The free-wheel comprises at least one barrier, the geometry of which varies depending on the speed of rotation of the driving part, arranged radially between the driving part and the driven part and longitudinally against the connection space, the barrier being constrained to rotate with the driving connection section.

Abstract: Systems and methods for preventing rotation of an ESP motor when the motor is not powered on, thereby preventing the motor from acting as a generator when fluid flowing through the pump section of the ESP applies a torque to the motor. In one embodiment, an ESP has a motor section, a pump section. The ESP may include a directional coupling that allows unidirectional rotation between the motor shaft and a pump shaft of the pump section, and a directional lock that allows unidirectional rotation between the motor shaft and a housing of the motor section. The directional coupling and directional lock allow the pump shaft to freewheel in the forward direction without causing the motor shaft to rotate, and prevent the pump shaft and motor from rotating in the reverse direction.
