PISTON ENGINE AND STIRLING ENGINE

摘要

A piston 20 is coupled to a connecting rod 13 which is rotatably coupled to a crankshaft 10 via an extension rod 12. With the configuration, reciprocating motion of the piston 20 is transmitted to the crankshaft 10 and converted to rotational motion. At both ends of the extension rod 12, a piston-side joint mechanism 30P and a crankshaft-side joint mechanism 30C each constructed by a spherical sliding bearing are provided. The piston 20 is coupled to the extension rod 12 via the piston-side joint mechanism 30P, and the extension rod 12 is coupled to the connecting rod 13 via the crankshaft-side joint mechanism 30C.
