摘要： In a timing chain driving system in which the speed of a driving sprocket fluctuates cyclically, the tooth pitch of a driven sprocket from which a tension span of the chain travels toward the driving sprocket varies cyclically around the circumference of the driven sprocket so that the tooth pitch at the point at which the timing chain disengages from the driven sprocket is at a minimum when the rotational speed of the driving sprocket is maximum, moderating fluctuations in chain tension. A similar effect can be achieved in the case of a driving sprocket having a cyclically varying tooth pitch by arranging the driving sprocket so that its tooth pitch is maximum at the point at which it is engaged by the chain when its rotational speed is maximum.

摘要： In the timing drive of an internal combustion engine, cyclic variations in chain tension, in the span traveling from a camshaft sprocket toward the crankshaft sprocket are leveled by synchronous reciprocating movement of a guide in sliding contact with that span of chain. The maximum rearward speed of the guide coincides approximately with the maximum tension in the span of chain, and the maximum forward speed of the guide coincides approximately with the minimum tension in the chain.

摘要： In a hydraulic tensioner, a tensioner housing is provided with an oil outflow channel communicating with a high pressure oil chamber formed by a plunger and the tensioner housing. A control valve in the oil outflow channel can be adjusted manually or automatically to optimize the damping performance of the tensioner in different engines and under different operating conditions, thereby obviating individualized machining of tensioner components to achieve optimum damping.
