摘要： A constant-velocity joint can have three pieces: a yoke, a first adaptor, and a second adaptor. Grooves on opposite sides of the yoke can receive forks of the adaptors and be perpendicular to one another. The yoke can have a guide surface within each groove so that a matching following surface on the fork of the adaptor can engage the guide surface to guide the movement of the fork within the groove. The adaptors may pivot within the grooves such that surfaces of flanks of the forks remain engaged or provide a consistent amount of surface contact with flanks of the groove throughout the pivot of the forks. Torque can be transferred through the engaged flanks as the joint is used to convert eccentric rotation to concentric rotation.

摘要： The disclosure describes a constant velocity joint assembly for use in transmitting torque. The constant velocity joint assembly includes members that are connected in series via tongue-and-groove connections in a swivel joint pattern that allows for transferring torque between two skew lines, and further provide freedom of movement such that rotation about one longitudinal axis can be transformed into rotation about another longitudinal axis that is not aligned with the first longitudinal axis. Thus, the members of the constant velocity joint assembly do not necessarily need to share a common longitudinal axis.

摘要： A drilling system (20) has a drill string (26) that is made up of tubular segments (54) of coiled tubing joined together by connectors (56). The connectors can be selectively changed between locked and unlocked configurations. When in the unlocked configuration adjacent tubular segments rotate with respect to one another, and when in the locked configuration the tubular segments are rotationally affixed. The connectors include clutch members coupled to each tubular segment, that axially slide into a slot formed in an adjacent tubular segment to rotationally lock the adjacent segments. A Kelly bushing and rotary table (36) rotate the drill string; and an injector head (28) is used to insert the drill string through the Kelly bushing and rotary table and into a wellbore (40). While the drill string is inserted through the bushing and table, the connectors are set into the locked configuration so that all tubular segments from the rotary table downward are rotationally affixed.
