A number of variations may include a product that may include a linking member that may have links arranged in rows that have multiple pitch lengths. Each of the rows may have at least one link. Each of the multiple pitch lengths may be a discrete length that may be different from others of the multiple pitch lengths. The rows may be arranged along the linking member in a repeating sequence of the multiple pitch lengths.

A device and a method can be utilized to measure concentricity of an internal toothing of a component. Such a device may include a determination segment, which can determine a concentricity deviation, that includes a spindle unit comprising a tapping spindle with a gauge gear wheel arranged thereon and intended for tapping the concentricity of the internal toothing, and an output spindle for transmitting the tapped concentricity from the tapping spindle to a measuring unit. The output spindle may be arranged directly or indirectly on the tapping spindle. A spindle holder may hold and position the tapping spindle, the output spindle, or the spindle unit. An adjusting element may position the gauge gear wheel, and the measuring unit may compare the tapped concentricity with reference values.

A pulley wheel rack includes a first rack part and a second rack part; a pulley wheel space between the first rack part and the second rack part; a first frame arranged to the first rack part, and a second frame arranged to the second rack part; an axle configured to extend from the first frame to the second frame, and configured to be rotatable into different securable positions by a ball joint arranged into the first frame and the second frame; and a pulley wheel bearing-mounted on the axle by hub bearings, and including at least one traction surface for engaging an elevator rope. A method for aligning a pulley wheel in a pulley wheel rack is also disclosed.

Methods and systems are provided for a pulley insert. In one example, a pulley insert for a FEAD pulley comprises a first member insertable into a pulley such that the first member is rotatable within the pulley, the first member comprising a cavity for receipt of a second member; and a second member insertable into the cavity of the first member such that, when the first member is inserted into a pulley and the second member is inserted into the cavity of the first member, the second member prevents rotation of the first member relative to the pulley.

A variable transmission system for a vehicle is configured such that, when a magnitude of a hydraulic pressure detected by an hydraulic pressure sensor is a first predetermined value or more, a chord portion of a chain belt is pressed such that a raceway length of the chain belt is extended by at least a circumferential extension amount of the chain belt at the time when the magnitude of the hydraulic pressure is the first predetermined value. Hereby, it is possible to restrain the chain belt from coming off from a sheave even in a low vehicle speed range, at a low cost, without causing a fuel efficiency decrease and a driving torque decrease of the vehicle.
