  • Process for the mounting of a group of component parts on a support element, in particular parts of a timing gear of a heat engine, and a packing print for carrying out this process
    Patent number: 4770399
    Abstract: The packing print for receiving in particular component parts (2-7) of a timing gear of a heat engine provided with a camshaft and a crankshaft, comprises cavities (2a, 3a, 4a, 5a) adapted to receive the component parts (2-7), in particular a camshaft wheel (2), a crankshaft pinion (3), a tension-producing device (5) and a guiding device (7) for a transmission chain (4) or belt associated with the pinion (3) and the wheel (2), these cavities being so arranged that the component parts (2-7) received therein are pre-positioned and pre-oriented with respect to one another in the exact positions they must occupy on the engine so as to permit the mounting of the component parts simultaneously on the engine. This print permits carrying out the mounting very rapidly with no risk of error in the positioning of the component parts.

  • Detachable timing gear cassette unit for an explosion or internal combustion engine
    Patent number: 4607601
    Abstract: A detachable timing gear cassette unit for an internal combustion engine. The cassette has side walls separate from the cylinder block of the engine, and the side walls form a housing. The housing contains the camshaft sprocket, the crankshaft sprocket, a timing chain that connects the sprockets, a tensioner to maintain a suitable tension in the timing chain and positioning ribs to position the sprockets within the housing. Engine oil is circulated through the housing, in a generally downwardly direction, to lubricate the sprockets and the chain and to cool the oil. The cooling of the oil is assisted by internal ribs on the inside of the housing and by external ribs on the outside of the housing.

  • Universal tightener for a transmission chain or belt
    Patent number: 4505691
    Abstract: The tightener includes a contoured strip adapted to bear against the chain or belt and be pivotally mounted on a fixed support member. A wedge member slidably mounted on the support member is elastically biased by a spring and urges the contoured strip against the chain or belt. A guide rod extends through a bore in the wedge member and the spring is mounted on the guide rod. A plate slidably mounted on the guide rod between the spring and the wedge member along one of the edges of the plate and thereby create an eccentric force which jams the plate on the guide rod.
