Biodegradable Plastic Gears.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1994
Presently, we often hear the phrase "plastics friendly to the global environment", and that a biodegradable plastic is being developed. However, no case has been reported up to now of mechanical parts being made of such plastics. Therefore, focusing the characteristics of this plastic, we have carried out a study to utilize this plastic for gears.
