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.

Method and system are provided for a quick connector for coupling conduits. The quick connector comprises a first piece including a radial slot and a first protrusion group, a second piece including a first slot group and a second slot group angled in a same direction, the first slot group is counterpart to the first protrusion group, and a third piece including a second protrusion group counterpart to the second slot group, where each slot of the first slot group faces a first side, and each slot of the second slot group faces an opposing, second side. In one example, the quick connector may include a locking mechanism and a feedback system.

A drum cylinder unit includes a photoconductive drum and a flange member. The flange member includes a fixing portion fixed to an end of the photoconductive drum, a cylindrical portion which forms a hollow portion therein, a groove portion provided at an edge of the cylindrical portion, and a gear portion.

A powered surgical stapling device includes an end effector having a stationary anvil and a cartridge assembly that is supported for pivotal movement in relation to the anvil. In embodiments, the end effector includes a housing that supports an input shaft, an anvil fixedly supported on the housing, and a cartridge assembly pivotally supported in relation to the housing and the anvil. The cartridge assembly includes a channel that is pivotally supported on the housing. A lead screw is positioned within the channel and supports an internally threaded dynamic clamping member. The lead screw is secured to the input shaft by a universal joint such that rotation of the input shaft effects rotation of the lead screw and longitudinal translation of the dynamic clamping member along the lead screw. The universal joint facilitates the translation of the rotatable movement of the input shaft into rotation of the lead screw while allowing pivotal movement of the lead screw in relation to the input shaft.

A steering mechanism of an all-terrain vehicle includes: a steering shaft; a power steering system; and an adjusting mechanism including a ball joint, a first connecting shaft and a second connecting shaft. The first connecting shaft has a first end provided with a first ball groove, the second connecting shaft has a first end provided with a second ball groove, and the first ball groove and the second ball groove each accommodate a partial structure of the ball joint, such that the first connecting shaft and the second connecting shaft are rotatably coupled by the ball joint; and a second end of the first connecting shaft away from the first ball groove is coupled to the steering shaft, and a second end of the second connecting shaft away from the second ball groove is coupled to the power steering system. An all-terrain vehicle is also disclosed.

A coupling assembly adapted for use on an item of equipment having a first component and a second component and including an eccentric axis plate having a first surface that is operatively connected to the first component and a second surface having a drive tang extending therefrom, a slider plate having a first surface that is in operational contact with the drive tang and having a first groove therein and a second surface having a second groove therein, and an adapter plate having a first surface that is in operational contact with the slider plate second surface and having an adapter plate tang extending therefrom and a second surface that is operatively connected to the second component. The longitudinal axis of the first component and the longitudinal axis of the second component are non-parallel, and the assembly is adapted to couple the first component and the second component.

A developing cartridge includes: a developing roller rotatable about a first axis extending in a first direction; a developing roller gear rotatable together with the developing roller; a coupling gear rotatable about a second axis extending in the first direction; and a joint rotatable together with the coupling gear. The coupling gear is meshingly engaging with the developing roller gear. The joint is pivotally movable relative to the coupling gear about a third axis extending in a second direction. The joint includes: a first protrusion extending in a first radial direction; and a second protrusion extending in a second radial direction opposite to the first radial direction. The second protrusion is positioned away from and is aligned with the first protrusion in a diametrical direction including the first radial direction and the second radial direction. The second direction crosses the first radial direction and the second radial direction.

A universal joint configured to transfer rotational movement from a first shaft to a second shaft at an angle and method of manufacturing the same.

A constant velocity connection for use in a drill string can include at least one ball-and-socket joint, and an insert rotationally received in an opening formed laterally through a ball of the joint. A method of constructing a constant velocity connection can include installing an insert in an opening formed in a ball of at least one ball-and-socket joint of the constant velocity connection, and allowing the insert to rotate in the opening about a lateral axis. A drill string can include a drilling motor, a drill bit, and a constant velocity connection connected between the drilling motor and the drill bit, the constant velocity connection including at least one ball-and-socket joint, and an insert rotationally received in an opening formed laterally through a ball of the joint.
