Fundamental Researches on a Perfectly Balanced Rotation-Reciprocation Mechanism. : Report 4, Static Balanced Theory of Rotation-Reciprocation Mechanism, and Comparison between Perfectly Balanced Rotation-Reciprocation Device and known Piston-Crank Devices

抄録

The static balanced theory of a rotation-reciprocation mechanism is established, and it is described that this theory is general one which can be applied to the perfectly balanced rotation-reciprocation mechanism and the known piston-crank devices. From the theoretical and experimental comparisons between the perfectly balanced rotation-reciprocation mechanism and the four kinds of known balanced piston-crank devices (containing the static balanced piston-crack device), it is ascertained that the former is much superior to the latter in the vibration, the friction loss between a cylinder and a piston, and the load to a connecting rod. However, the former is a little more complex than the latter in the construction. And it is clear that the static balanced piston-crank device can not be put to practical use without any improvements.
