摘要： A roller chain sprocket includes a number of sprocket teeth each having an engaging flank and a disengaging flank. An engaging flank of a first tooth of the sprocket cooperates with a disengaging flank of a second tooth to define a tooth space having a root surface extending between the engaging flank and the disengaging flank. The root surface has a first root surface portion defined by a first radius extending from an arc center of the first root surface portion. A cushion ring is mounted to a first face of the sprocket and has a number of alternating compression pads and grooves. A first groove has a first groove portion defined by a second radius extending from an arc center of the first groove portion. The arc center of the first groove portion being positioned at least proximate a radial line extending between a center of the sprocket and the arc center of the first root surface portion. A first compression pad having an inclined outer surface defined by a leading edge that is spaced radially inward relative to a trailing edge. The leading edge is also positioned radially inward from the engaging flank of the first tooth, and the trailing edge is positioned radially inward from a disengaging flank of the first tooth.

摘要： A unidirectional roller chain sprocket for use primarily in automotive engine chain drive applications which incorporates an asymmetrical tooth for improved noise reduction. The asymmetrical tooth profile incorporates a flank flat which is tangent to an engaging flank radius and a first root radius. The asymmetrical tooth profile also incorporates one or more inclined root surfaces which provide tooth space clearance for maintaining the chain rollers in hard contact with the root surface in the sprocket wrap. The asymmetrical tooth profile further incorporates pitch mismatch wherein the sprocket chordal pitch is less than the chain chordal pitch to facilitate a "staged" roller-tooth contact as a roller moves into full mesh from an initial tangential impact at the flank flat.

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.

摘要： A unidirectional roller chain system for use primarily in automotive engine camshaft drive applications wherein the tooth profile of the sprockets are modified for noise reduction. This new tooth profile is asymmetrical with flank radii that may differ from the drive side to the coast side of the tooth. This configuration lowers the overall noise level of the chain drive system by reducing the engagement impact energy as the sprocket collects a roller from the span, and maintaining the chain rollers in hard contact with the root surface in the sprocket wrap.

摘要： Electrographic stylus recording apparatus for producing a magnetically attractable toner powder image on a receptor belt including two rotatable cylindrical sleeves, each having a non-rotatable magnetic roll, with one sleeve positioned adjacent the upstream side of a stylus array and the other sleeve adjacent the downstream side with each of such sleeves adapted for connection to a d.c. source, the upstream sleeve being connected to a d.c. source to place toner powder on the receptor belt for delivery of toner powder to the stylus array when a toner image is to be made and the downstream sleeve being connected to a d.c. source to place toner powder on the receptor belt from such sleeve for return to the upstream side of the stylus array via the receptor belt. The magnet rolls within the sleeves are positioned to provide like magnetic poles to the stylus array to provide a magnetic flux at the recording ends of the styli in the array. Each of the magnetic rolls also provide a magnetic pole to the receptor belt at the point where the sleeves are closest to the receptor belt.

摘要： A sprocket for an inside flank engagement inverted tooth chain includes tooth spaces each defined at least partially by the engaging flank of one tooth, the disengaging flank of another tooth, and a root surface that is located between the engaging flank and the disengaging flank of the tooth space. The engaging flank of each tooth space is defined as a mirror image of the disengaging flank of each tooth space relative to a tooth space centerline such that each tooth space is symmetrically defined about its tooth space centerline. The sprocket teeth include Type A Standard Teeth, Type B Standard Teeth, Type A Relieved Teeth, and Type B Relieved Teeth. The engaging flank of each Type A Relieved Tooth and both the engaging and disengaging flanks of each Type B Relieved Tooth are relieved or negatively offset. The root surface preceding a Type A Relieved Tooth or a Type B Relieved Tooth is raised so as to be located radially outward as compared the root surface preceding a Type A Standard Tooth or a Type B Standard Tooth.

摘要： An inverted tooth chain and sprocket drive system in which the initial contact distance ICD, the meshing impact angle Sigma (σ), the link plate entrance angle Beta (β), and other aspects of the meshing geometry are controlled and optimized to reduce noise and vibration by using a particular chain link plate form and, in preferred cases, by modifying the sprocket tooth pressure angle. The system can include first and second sprockets for which the pressure angle can be controlled to ensure that the desired values for the initial contact distance ICD, the meshing impact angle Sigma (σ), and the link plate entrance angle Beta (β) are equal for both sprockets even though the sprockets have different tooth counts. For a chain pitch P in the range of 6.35 mm to 7.7 mm, the initial contact distance ICD is controlled such that 0.49 P≦ICD≦0.53 P, the meshing impact angle Sigma (σ) is controlled such that σ≦34°, and the link plate entrance angle Beta (β) is controlled such that β≦9°. For certain alternative chain and/or sprocket configurations, σ≦33° and β≦9°, or σ≦31° and β≦7°.
