    • ISSUE To reduce operating noise and further improve durability in a cushioning structure for a sprocket used in a roller chain or bush chain. MEANS OF RESOLUTION Annular first and second cushion rings 2, 3 are provided in such a way as to be able to slide against each other around grooves 10a in a sprocket 1. The first cushion ring 2 consists of a single wire and has a wave-like shape comprising a plurality of projections 2a. The second cushion ring 3 consists of a single wire and has a circular shape running around the outer circumference of the sprocket 1. When a roller chain 5 meshes with the sprocket, the rollers 50 make contact with the second cushion ring 3 causing the second cushion ring 3 to elastically deform, then causing the first cushion ring 2 to elastically deform. At this point, the first and second cushion rings 2, 3 slide against each other. As a result, the impact noise of the rollers 50 and the sprocket teeth 10 is effectively reduced.

    • A drive sprocket for machines such as a motorcycle includes cushioning elements to reduce spikes in stress levels between the machine's power transmission and a driven member, such as the wheel of motorcycle. The sprocket has an inner plate (10) which is located coaxially within the outer ring (9). The inner plate (10) is formed with outwardly projecting lugs (8) A that are arranged to mesh with the inwardly projecting lugs (7) of outer ring (9). The outwardly projecting lugs comprise six wide lugs (8A) and six narrow lugs (8B) disposed alternately around the outside of the inner ring. The outer edge of outwardly projecting lugs, (8A), (8B) are formed with a bearing slot (41). In the case of the six wide lugs, their bearing slot (41) cooperate with bearing slots (37) on the inside wall of the outer ring (9) to provide a ball bearing race for bearings (12). The sides of the lugs (8A,8B) are also formed with cushion slots (43) to engage cushioning elements (45) and (47).

    • A sprocket (S) for a chain driven power transmission system used on an internal combustion engine. Severe ITVH (Noise, Vibration, Harshness) characteristics associated with a chain engaging the sprocket is damped by two annular rings (Rl, R2) that are loosely positioned on either side of the circumferential row of teeth. The inner diameters (IDl, ID2) of each of the annular rings (Rl, R2) form cavities between the annular rings and the sprocket grooves. Pressurized viscous fluid is supplied to each cavity via channels in the hub of the sprocket to cushion the impact of each roller of the chain as it engages each row of teeth during engine operation. The pressure of the viscous fluid creates a resistive force to minimize the severe impact noise experienced by non-damped sprockets.

    • The problem of progressive deforming of the silencing rubber by the motion transmission member (chain) is present in silenced sprockets. In particular for a toothed crown, lacking a central hub, the problem of the deforming or "lowering" of the rubber hasn't been resolved adequately. In the case of a pinion with a hub, an excessive quantity of rubber is used. The silenced sprocket of the present invention comprises, adjacent to the base of its teeth (105'), a circular channel, or bilateral channel (200), on the metal body of the sprocket itself. On the inner circular step (110') of the channel (200) are discharged the forces created in the rubber by the transmission chain. The bilateral channel has a minimal radial extension, such as about ½ cm in the motorcycle field. In general the silencing rubber element (106') and the bilateral channel (200), which creates its housing, have a minimal radial extension compared to the sprocket radius. The invention also comprises a molding technique that uses special molding components (107a, 107b), adapted to apply the rubber silencing element on the sprocket metal body. These components are of annular circular shape, U cross section and a width essentially corresponding to the channel (200) width, rendering the mold independent from the specific shape of the sprocket metal body.
    • 沉没的链轮中存在由运动传递部件(链)使消音橡胶逐渐变形的问题。 特别是对于缺少中心轮毂的齿形冠,橡胶的变形或“降低”的问题尚未得到充分解决。 在具有轮毂的小齿轮的情况下,使用过量的橡胶。 本发明的沉没链轮包括邻近其齿(105')的基部的在链轮本身的金属体上的圆形通道或双向通道(200)。 在通道(200)的内圆周台阶(110')上通过传动链排出由橡胶制成的力。 双边通道具有最小的径向延伸,例如在摩托车领域约为1/2厘米。 通常,消音橡胶元件(106')和产生其壳体的双边通道(200)与链轮半径相比具有最小的径向延伸。 本发明还包括一种成型技术,其使用适于将橡胶消音元件施加在链轮金属体上的特殊模制部件(107a,107b)。 这些部件具有环形圆形,U形横截面和基本上对应于通道(200)宽度的宽度,使得模具独立于链轮金属体的特定形状。
