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： An inverted tooth chain drive system defines a meshing contact angle Tau (τ) between the tangent line TL and an initial contact reference line that passes through a controlling pin center and the initial contact location. A link plate entrance angle Beta (β) is defined between the initial contact reference line and an inside flank reference line that passes through an arc center of the inside flank radius and the initial contact location. A meshing impact angle Sigma (σ) is defined between the tangent line and the inside flank reference line such that σ=τ+β, wherein β≦9° and σ≦34°. The pressure angle of the sprocket tooth can be adjusted and the chain optimized such that β≦7° and σ≦31°. The system thus provides a reduction of the link impact force FL and the resultant impact energy E. The inverted tooth chain, itself, defines a pitch P and an inside flank projection Lamda (λ) such that 0.007×P≦λ≦0.017×P when said chain is pulled straight. The outside flanks include a chamfer to ensure that initial contact between the chain and sprocket is always on the leading inside flanks of the chain.

摘要： An inverted tooth chain drive system includes an inverted tooth chain structured for inside flank engagement. The chain includes link rows each including leading inside flanks that project outwardly relative to trailing outside flanks of a preceding link row. The system further includes a sprocket with which said inverted tooth chain is drivingly engaged. The sprocket includes a plurality of teeth circumferentially spaced about an axis of rotation, each tooth comprising an engaging flank and a disengaging flank. Some of the teeth are defined with a first tooth form in which said engaging flank thereof is defined with a first pressure angle and others of said teeth are defined with a second tooth form in which the engaging flank thereof is defined with a second pressure angle that is different from the first pressure angle in order to stagger or modulate the initial meshing impacts between the leading inside flanks of the chain and engaging flanks of the sprocket teeth. The sprocket can be optimized for manufacture by a hobbing process, by arranging the different tooth forms in a specific “hob-compatible” pattern.

摘要： A sprocket includes a hub and a plurality of teeth projecting radially outwardly from the hub. At least one cushion ring is located adjacent the teeth, and the cushion ring defines a plurality of compression pads separated from each other by transverse grooves. Each of the compression pads is defined symmetrically about a circumferential mid-point. When part of a sprocket with symmetric tooth spaces, the cushion ring is being operable identically in first and second opposite rotational directions. In one arrangement, the compression pads each include a planar outer surface having a leading and a trailing end, wherein the leading end and trailing end are located a common radial distance from a center of the hub about which the sprocket rotates. The tooth spaces of the sprocket can be symmetric, asymmetric and the root surface can be relieved. The sprocket can include multiple tooth profiles distributed randomly about the hub.

摘要： A chain tensioner apparatus utilizes a synthetic plastic (e.g. nylon) bracket that permits a fastener at a pivot end of the bracket to serve as a pivot pin for a shoe sub-assembly as well as a bracket fastener. A free end fastener can be positioned very close to, or substantially below, a reaction surface of the bracket. An interlocking feature is provided at a pivot end of the bracket/shoe sub-assembly and serves to maintain an interlock of the shoe-to-bracket in cooperation with an installation pin. Additionally, a positioning feature is used at the pivot end of the bracket. In order to permit the free rotation of the shoe relative to the bracket, the pivot end of the bracket is not clamped rigidly to the engine case when a pivot end bolt is installed. Further, a dowel pin can be used at the pivot end of the bracket.

摘要： An improved electrographic stylus recording apparatus wherein magnetically attractable toner powder used during imaging, but not forming a part of a toner image, is returned from one side of a stylus array to the toner powder hopper of the apparatus. The toner powder is transported around the stylus array by the use of fixed magnets disposed within two rotatable cylindrical sleeve members disposed on opposite sides of the stylus array. A further cylindrical sleeve member having a rotatable magnetic field producing means within the sleeve attracts toner powder from the cylindrical sleeve disposed on the toner powder hopper side of the stylus array for delivery to the toner powder hopper.
