  • Camshaft driving mechanism of double overhead camshaft engine
    Patent number: 5579664
    Abstract: A camshaft driving mechanism for driving camshaft wheel members secured to two camshafts in a cylinder head through a power transmitting member mounted between a crankshaft wheel member and the camshaft wheel members; in this driving mechanism, the thickness of the camshaft wheel members is one-half or less of the width of the power transmitting member, one of the camshaft wheel members is offset in an axial direction from the other camshaft wheel member, and the camshaft wheel members partly radially overlap, or one of the camshaft wheel member has a center slit in the axial direction while the other camshaft wheel member fits in the slit.
    Type: Grant

  • Power transmission mechanism with two sets of chains
    Patent number: 5116283
    Abstract: A chain-type power transmission mechanism, having first and second sets of sprockets, each set of which has a sprocket provided on both a drive shaft and a driven shaft. A first chain extends over and between the first set of sprockets, and a second chain extends over and between the second set of sprockets. The two sprockets provided on at least one of the shafts are relatively changeable in rotational position whereby the forward side of one chain and the backward side of the other chain are tensioned.
