    • A sprocket (112) is defined to include added chordal pitch reduction when in a new or "as-manufactured" condition. The sprocket chordal pitch Ps' is purposefully reduced as compared to the as-built chain pitch Pc (or a theoretical maximum sprocket chordal pitch) a select amount referred to herein as "added chordal pitch reduction." This added chordal pitch reduction is in addition to the inherent chordal pitch reduction that exists owing to manufacturing tolerances. A sprocket (112) incorporating added chordal pitch reduction is highly desired in that it facilitates extension of the meshing time interval for an associated chain roller. The sprocket (112) is formed to have a chordal pitch that is reduced relative to a maximum theoretical sprocket chordal pitch (or the chain link pitch) by an amount between about 0.2 % and about 1 % of the maximum theoretical sprocket chordal pitch.
    • 链轮(112)被定义为当在新的或“制造的”条件下包括增加的弦降高。 与本文中称为“增加的弦降高”的选择量相比,链轮弦节距Ps'被有目的地减小,与构造的链节距Pc(或理论最大链轮弦节距)相比。 除了由于制造公差而存在的固有弦降幅度之外,这增加了弦降幅度。 高度期望结合了增加的弦降幅度的链轮(112),因为它有助于相关链轮的啮合时间间隔的延长。 链轮(112)被形成为具有相对于最大理论链轮弦节距(或链节间距)减小的弦节距,该最大理论链轮弦节距(或链节间距)在最大理论链轮弦节距的约0.2%和约1%之间。

    • A random engagement roller chain sprocket for use primarily in automotive engine chain drive applications which incorporates different asymmetrical tooth profiles for improved noise reduction. In particular, the sprocket includes a first plurality of sprocket teeth each having a first tooth profile including a first engaging flank, a first engaging root, and a first flat positioned between the first engaging flank and first engaging root wherein a first roller initially contacts the first flat at the onset of the first roller meshing with the sprocket. The sprocket also includes a second plurality of sprocket teeth each having a second tooth profile different from the first tooth profile and including a second engaging flank, a second engaging root, and a second flat tangent to the second engaging root remote from the second engaging flank wherein a second roller initially contacts the second flat at the onset of meshing between the second roller and the sprocket. 00000

    • A unidirectional roller chain sprocket (112, 114) for use primarily in automotive engine chain drive applications which incorporates an asymmetrical tooth (132, 136) for improved noise reduction. The asymmetrical tooth profile incorporates a flank flat (144) which is tangent to an engaging flank radius (Rf) and a first root radius (Ri). The asymmetrical tooth profile also incorporates one or more inclined root surfaces (146) which provide tooth space clearance for maintaining the chain rollers (118, 128, 130) in hard contact with the root surface (146) in the sprocket wrap (158). The asymmetrical tooth profile further incorporates pitch mismatch wherein the sprocket chordal pitch (Ps) is less than the chain chordal pitch (Ps) to facilitate a "staged" roller-tooth contact as a roller moves into full mesh from an initial tangential impact at the flank flat (144).
