摘要:
The present invention relates to a mounting structure for mounting firmly onto a rotating shaft a rotational force transmission member such as a chain sprocket, a gear, a belt pulley and the like. A drive sprocket as a rotational force transmission member is fitted into an end of the rotating shaft in a splined manner. A coned disc spring and a washer are positioned in sequence onto an outer face of the rotational force transmission member. The coned disc spring and the washer are supported and sandwiched by the screw fastening member to be screwed to an end of the rotating shaft and the rotational force transmission member.

A lubricating structure for an engine includes a crankcase for supporting a crankshaft formed from a pair of case halves coupled to each other along a mating plane extending along a plane perpendicular to an axial line of the crankshaft. An oil reservoir in a lower portion of the crankcase extends across the mating plane. A pump chamber of an oil pump is formed between the two case halves across the mating plane. Lubricant is drawn from the oil reservoir into the oil pump using a structure which can achieve reduction of the number of parts and improve the ease of assembly. The structure includes a path groove, which forms an oil suction path for interconnecting the oil pump and the oil reservoir, formed in at least one of the two case halves.

The invention is directed at a device that reduces the size of an engine in the direction along the axis of a crankshaft. More specifically, it relates to an engine starting system in which a part of a starting power transmission gear train is provided between one end portion of a crankshaft rotatably borne on a crankcase and a starter motor mounted to the crankcase is covered from the outside by an accessory coupled to and operated in conjunction with the crankshaft.

This invention provides a hot forming mold made of xonotlite group materials such as xonotlite, or wollastonite made therefrom, which are known as a heat-resisting materials. By hot pressing these material to high bulk density e.g., 0.6 to 2.20, a mold suitable for use in hot forming, having increased sending strength and hardness can be efficiently made.Such molds are made by filter pressing an aqueous slurry of xonotlite, then drying the pressed product to remove moisture at a temperature less than about 700.degree. C., and then cutting out the mold for use in molding plastic, glass and the like. By heat treating this mold product at a temperature of about 700.degree. to 1200.degree. C. the mold so produced can be subjected to machining and can be used as a mold for superplastic forming aluminum, titanium and the like.

摘要:
A cylinder block, a cylinder head and a cylinder head cover are stacked in order to form a four-cycle engine. A valve train of a single overhead camshaft (SOHC) type provided with an intake valve and an exhaust valve is provided in the cylinder head. A line extending parallel with a joint between the cylinder head and the cylinder head cover is inclined forward and downward toward a line parallel with a joint between the cylinder block and the cylinder head. An axis of an exhaust valve and/or an axis of a plug tube is/are perpendicular to the line extending parallel with the joint between the cylinder head and the cylinder head cover. A cylinder head hanger is integrally formed at an uppermost end of a rear portion of the cylinder head over an intake port.
