Abstract: A fastener system for attaching bicycle chainrings to a bicycle crank comprised of a nut and a bolt. Both the nut and bolt consist of shafts with flanges on one end. The nut has threads formed on the interior of its shaft, while the bolt has threads formed on the exterior of its shaft. The nut and bolt can thus be threadedly engaged with each other to clamp the chainrings to the crank. Both the nut and bolt contain tool engagement interfaces formed on the interior of their respective shafts.

Abstract: 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.

Abstract: A sprocket is defined to include added chordal pitch reduction when in a new or nullas-manufacturednull condition. The sprocket chordal pitch Psnull 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 nulladded chordal pitch reduction.null This added chordal pitch reduction is in addition to the inherent chordal pitch reduction that exists owing to manufacturing tolerances. A sprocket 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 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.

Abstract translation: 链轮被定义为在新的或“制造的”条件下包括增加的弦降高度。 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。 非常希望包括加入弦节距减小的链轮，因为其有助于相关链轮的啮合时间间隔的延长。 链轮形成为具有相对于理论链轮最大桨距（或链节距）的最大理论链轮弦距的约0.2％至约1％之间的量减小的弦节距。

Abstract: A sprocket assembly includes a sprocket body comprising: (i) first and second hubs that project axially outward from opposite first and second axial faces; and, (ii) a plurality of teeth that extend circumferentially in a row and that project radially outward between the first and second hubs. Each of the teeth includes a drive flank and a coast flank. The drive flank and coast flank of at least some of the teeth are shaped differently from each other so as to define an asymmetric tooth profile. First and second metal cushion rings are captured and float eccentrically on the first and second hubs, respectively. The teeth are identical or multiple asymmetric tooth profiles are used on a single sprocket body and arranged in a regular or irregular pattern. The root surface between successive teeth can be relieved so that a space is defined between the root surface and a roller that bridges the root.
