摘要： A universal joint assembled to a drill string transfers torque and axial force between two components where the shafts of the components are not completely aligned. The universal joint includes end members connected to opposite ends of a cable for connecting to components of the drill string. As the joint rotates the cable flexes to accommodate misalignment between the connected drill string components.

摘要： A torque transfer mechanism includes an input member to receive an input torque from a propulsion source, and an output member coupled to the input member to transfer the input torque to a driveline component. A multi-component damping mechanism is disposed between the input member and the output member which includes a first spring element cooperating with a second spring element to couple the input member to the output member. The first spring element defines a greater stiffness and shorter deflection relative to the second spring element.

摘要： A universal joint includes a first band and a second band which are separated by a slot, are cylindrical and coaxial with one another with respect to a common axis, a first stiffener whose ends are joined to the first band, and a second stiffener whose ends are joined to the second band. A stem extends between the first stiffener and the second stiffener. A crown is around the stem. Four torsion bars exist, of which two extend between the crown and the first band and two extend between the crown and the second band.

摘要： In one embodiment, a selectable-rate spring comprises a flexure bar connected to a rotatable shaft, the flexure bar having at least one arched portion. The selectable-rate spring also includes at least one rotational contactor connectable to a link member, wherein the rotational contactor rotates about an axis while maintaining contact with the arched portion of the flexure bar. As the rotational contactor rotates, it changes the connection stiffness between the rotatable shaft and the link member.

摘要： A torque coupler includes a first torque plate having a first slot extending in a radial direction, and a second torque plate having a second slot extending in the radial direction. The second slot has a side formed of a flexible beam. A cam plate is pivotable about an axis, and has a cam slot having a first portion at a first radial distance from the axis and a second portion at a second radial distance, where the second distance is greater than the first distance. A torque transfer member is slidably received within the first slot, the second slot, and the cam slot. The transfer member transferring torque between the first and second torque plates. A drive device rotates the cam plate about the axis, which causes the first cam slot to radially slide the transfer member along the flexible beam.

A second actuator device (22; 122) is arranged to change the stiffness of the rotary joint (10; 110). The rotary joint (10; 110) includes an intermediate member (18; 118) hinged (44; 168) to the output member (12; 112) to rotate relative to the output member about a second axis of rotation (x2) parallel to the first axis (x1), abuts at its opposite end against the elastic elements (20, 64; 120) and is hinged (46; 150), at an intermediate point thereof, to the input member (16; 116) to rotate relative to the input member about a third axis of rotation (x3) parallel to the first axis (x1). Transmission of the torque between the input member (16; 116) and the output member (12; 112) takes place via the intermediate member (18; 118). The second actuator device (22; 122) is arranged to change the hinge point and the distance between the second axis of rotation (x2) and the third axis of rotation (x3).
