A ball-hinged transmission shaft with a straight shaft includes a socket, a ball, and a straight shaft. A rolling element is further coaxially provided on a straight shaft. The rolling element is a rotator with an axis of the straight shaft as a center of rotation. An upper portion of the rolling element is connected to a bearing. A mouth-shaped surface is further respectively provided at two ends of a transmission hole of a ball. The mouth-shaped surface is a curved surface matching the shape of the rolling element. The rolling element is fit and provided in the mouth-shaped surface at the two ends of the transmission hole of the ball. The ball is restricted by an inner positioning spherical surface of a socket, the straight shaft, and the rolling element at the same time.

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 system configured to couple an implement to a work vehicle includes a first lock assembly coupled to an arm of the work vehicle, and the first lock assembly includes a first lock, a second lock, and a first actuator configured to drive the first lock and the second lock laterally outwardly to engage respective first openings formed in the implement. The system also includes a second lock assembly coupled to a frame of the work vehicle, and the second lock assembly includes a third lock, a fourth lock, and a second actuator configured to drive the third lock and the fourth lock laterally outwardly to engage respective second openings formed in the implement.

A universal socket includes a barrel seat, a resilient member and a rotating component. The barrel seat has an inner wall surface having four receiving surface portions, and four linking surface portions each connected between two adjacent ones of the receiving surface portions and having two flat surface segments. The rotating portion is retained in the barrel seat, and has four corner surfaces corresponding in position to the receiving surface portions, respectively, and four contacting surfaces each connected between two adjacent ones of the corner surfaces and biased by the resilient member to abut against one of the flat surface segments.

Articulable joints having diamond bearing surfaces engaged with metal bearing surfaces are provided herein. The articulable joints provide multiple degrees of freedom to components, such as drivelines, and bear loads in multiple directions. The articulable joints include diamond bearing surfaces slidingly engaged with opposing metal bearing surfaces that include more than trace amounts of diamond solvent-catalyst.

The present invention relates to a measuring device with a magnetic field sensor for detecting at least one operating parameter of an agricultural joint shaft for torque transmission between a power take-off shaft of a towing vehicle and a transmission of an agricultural appliance, which includes at least one journal cross, to the opposing journals of which a shaft body is connected, and a protective tube rotatably accommodating the shaft body therein, wherein the magnetic field sensor is adapted to measure a magnetic field emanating from the bare shaft body of the joint shaft.

A joint shaft includes at least one cross pin, the at least one cross pin including oppositely disposed pins on each of which a shaft member is attached; and a generator attached to at least one of the shaft members. The joint shaft may further include a sensor energized by the generator and attached to the joint shaft and/or a logic configured to evaluate an electrical output of the generator.

Modular tracker systems that include at least first and second tables or are continuous without the use of tables, a single motor driving the first and second tables, first and second intra-table drive shafts and an inter-table drive shaft. Each table includes a support structure including first and second mounting posts, a frame supported by the support structure, at least one solar panel supported by the frame, and first and second gearboxes being concentrically aligned for each table. The first and second gearboxes are each configured to produce first and second outputs. The first output has a first rotational speed, and the second output has a second rotational speed less than the first rotational speed, and is operatively coupled to the frame. The inter-table drive shaft couples the second gearbox of the first table with the first gearbox of the second table, whereby the first and second tables are rotated synchronously.

The present invention provides a wide angle joint including: a pair of yoke shafts mounted on opposite sides thereof to transmit power from the one side to the opposite side, each yoke shaft having a ball end portion provided on a first yoke part to which a spider is coupled; a plate having a large-diameter part formed in the middle thereof and protruding parts protruding from the large-diameter part in the opposite axial directions while being reduced in a radially inward direction, wherein the protruding parts have insertion recesses into which the ball end portions of the yoke shafts are inserted, and the large-diameter part is faulted to have different widths in radial directions from the central portion thereof; and a pair of coupling yokes, each of which has a second yoke part connected with the first yoke part through the spider and a support recess into which the large-diameter part of the plate is inserted.
