Claims (1)
固定したカムスプロケットとの間にタイミングベルトを
張設し、該タイミングベルトを介して前記クランク軸の
回転をカム軸に伝達するようにした内燃機関の回転伝達
機構において、互いに対向する内側の面に環状の吸音材
を固定した一対の環状部材を、前記カムスプロケットの
両側面に対向させて取り付け、該カムスプロケットの歯
部及ひ前記タイミングベルトの歯部の両側面を、前記吸
音材によって接触しない程度の小間隙を設けて覆うよう
にしたことを特徴とするカムスプロケットの防音構造。Rotation of an internal combustion engine in which a timing belt is stretched between a crank sprocket fixed to a crankshaft and a cam sprocket fixed to a camshaft, and the rotation of the crankshaft is transmitted to the camshaft via the timing belt. In the transmission mechanism, a pair of annular members having annular sound-absorbing material fixed to opposing inner surfaces are attached to opposite sides of the cam sprocket, and the teeth of the cam sprocket and the teeth of the timing belt are attached to opposite sides of the cam sprocket. A soundproof structure for a cam sprocket, characterized in that both sides of the cam sprocket are covered by the sound absorbing material with a small gap between them so that they do not come into contact with each other.
