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 stepless transmission transmits a driving force by an endless transmission member (5) wound around a V-groove (6) of an input pulley (1). The input pulley (1) has moving parts (9) which are fastened by threaded engagement so as to be axially movable with respect to a transmission case (3) and have ring gears (10), to which rotation can be input from the outer periphery sides, and pulley half discs (13) which are relatively rotatable with respect to the moving parts (9), which axially move integrally with the moving parts (9) and which are contactable with an endless transmission member (5). The pulley half discs (13) and an input shaft 2, which is disposed at the center of the pulley half discs (13), rotate together as one piece. The ring gears (10) are each rotationally driven from a drive source of the same drive member.

A washing machine is provided. The washing machine includes an input shaft, configured to supply a rotary power to a rotation part for rotating washings; a motor, configured to rotate in a forward direction and backward direction and served as a power source of the rotation part; and a transmission arranged between an output shaft of the motor and the input shaft of the rotation part. The transmission includes a transformable driving side pulley unit disposed on the output shaft; a transformable driven side pulley unit disposed on the input shaft; and a driving belt for transferring power between the pulley unit and the driven side pulley units. The driving side pulley unit/driven side pulley unit is directly installed on the output shaft/input shaft by locating each end of the output shaft/input shaft at a movable pulley and a fixed pulley respectively, so that the driving side pulley unit/driven side pulley unit rotates integrally with the output shaft/input shaft.

In one example in accordance with the present disclosure an apparatus for attaching to a shaft using a wedge is described. The apparatus includes a disc having a longitudinal axis. At least a portion of the disc is insertable into a shaft and is expandable against an inside diameter of the shaft. The disc has a recess at the longitudinal axis. A wedge to be inserted into the recess pushes the portion of the disc that is insertable into the shaft against an inside diameter of the shaft.

In one variation, a pulley arrangement includes a base pulley portion rotatable within a driving plane, an adjustable pulley portion coupled to the base pulley portion wherein the adjustable pulley portion is rotatable relative to the base pulley portion within the driving plane, and a driving member including an end coupled to the adjustable pulley portion wherein at least a portion of the driving member is wrapped at least partially around the adjustable pulley portion. In another variation, a pulley arrangement includes a base pulley portion rotatable around an axis, an adjustable pulley portion coupled to the base pulley portion and movable in a first direction parallel to the axis, and a sliding block engaged with the adjustable pulley portion, wherein the sliding block moves in a second direction different from the first direction, in response to compression of the adjustable pulley portion against the base pulley portion.

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.
