摘要： In the present invention, dislodging of a belt is prevented even when there is slack in a fastening member that secures a movement-side pulley for adjusting an inter-axial distance. An adjustment mechanism that adjusts an inter-axial distance between a first pulley and a second pulley is provided with a support member to which the first pulley is provided, first and second long holes provided in an arm part body, first bolts that are inserted into the first long holes and that fasten the support member to the arm part body, and second bolts that are inserted into the second long holes and that fasten the support member to the arm part body. The first long holes have a first length that enables the support member to move toward the second pulley until the inter-axial distance reaches a distance at which the belt can be wound between the first and second pulleys. The second long holes have a second length that retains the inter-axial distance at a distance such that the state in which the belt is wound between the first and second pulleys is not dislodged.

摘要： A chain tensioning device is basically provided with a main body, a chain guide and a rotary fluid damper unit. The main body is configured to be mounted to a bicycle. The chain guide is pivotally coupled to the main body to rotate around a rotational axis with respect to the main body. The rotary fluid damper unit is operatively connected between the main body and the chain guide to provide rotational resistance to the chain guide around the rotational axis. The rotary fluid damper unit is a separate unit from the main body, the rotary fluid damper unit being detachably mounted on the main body.

摘要： A fixed or adjustable chain guide includes a captured shoulder bolt fastener. An adjustable chain guide such as a chain tensioner arm assembly includes a tensioner arm with a pivot bore defined about a pivot axis. The pivot bore includes an inner end opening through a rear face of the tensioner arm and an outer end opening through a front face of the tensioner arm. The tensioner arm further includes at least one resilient fastener retaining tab located adjacent the pivot bore. The shoulder bolt extends through the pivot bore and is engaged by the at least one resilient fastener retaining tab, and the at least one fastener retaining tab inhibits separation of the fastener from the tensioner arm. The fastener preferably includes an annular groove or other recess to be engaged by the one or more fastener retaining tabs in order to permit the tensioner arm to rotate relative to the fastener. New shoulder bolt fasteners are also defined, each including a shoulder region having at least one retaining feature such as an annular groove adapted to be engaged by a projecting portion of an associated component for axially capturing the fastener to the associated component while permitting rotation of the associated component relative to the fastener.

摘要： A novel tensioner for use with flexible drives, such as serpentine accessory belts on automobiles includes a tensioner arm to spindle pivot design which employs a frustoconical bushing between an inner pivot surface of the tensioner arm and a spindle shaft. The frustoconical design of the bushing resists off axis movement of the tensioner arm and a wear take up mechanism biases the bushing into contact with the inner pivot surface to compensate for normal wear of the bushing and/or pivot surface. A thrust plate is mounted to the end of the spindle shaft and rides in a thrust washer, the thrust plate and thrust washer being held captive in the tensioner arm such that the tensioner arm can pivot about the bushing and the spindle and the thrust plate and thrust washer assist in inhibiting off-axis movement of the tensioner arm. In one embodiment, the biasing force which biases the bushing against the inner pivot surface of the tensioner arm can be varied to change the amount of dampening of the tensioner.
摘要翻译：一种用于柔性驱动器的新型张紧器，例如汽车上的蛇形附件带，包括一个主轴枢轴设计的张紧器臂，其在张紧器臂的内部枢转表面和主轴之间采用截头圆锥形衬套。衬套的截头圆锥形设计抵抗张紧器臂的轴向移动，并且磨损吸收机构偏置衬套与内部枢轴表面接触以补偿衬套和/或枢转表面的正常磨损。推力板安装到主轴的端部并且骑在止推垫圈中，推力板和止推垫圈被保持在张紧器臂中，使得张紧臂能够围绕衬套和主轴和推力板枢转，并且止推垫圈有助于抑制张紧臂的离轴运动。在一个实施例中，可以改变使衬套偏压张紧器臂的内部枢转表面的偏置力，以改变张紧器的阻尼量。
