TRANSACTIONS 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.

Fatigue Life Analysis of the Plastic Helical Gear and Steel Worm Transmission Mechanism
Jixie chuandong, 2023 The rapid development of polymer materials has promoted the trend of plasticization of metal gears in medium and low load gear transmissions. Plastic helical gears are often used to replace metal worm gears in the worm and helical gear transmission, but ...

DEVELOPMENT OF PLASTIC GEARS FOR POWER TRANSMISSION : Power Transmission Mechanism of Plastic Gears
Bulletin of JSME, 1984 The plastic gears excel in the self-lubrication, the low noise and others over the steel ones. But they are not suitable for power transmission because of their low load carrying capacity and short lifetime. In the present paper, the power transmission mechanism of the plastic gears is clarified theoretically and experimentally. And then the causes for

Bulletin of JSME, 1985 The life of plastic gears is shortened when they are used at a high temperature because they become less strong and vary in the way they mesh each other, causing them to be worn away at their root in an abnormal way. It is necessary for lengthening the life of plastic gears to take care not to generate heat in them and to keep them from rising in ...

Durability Investigation of plastic gears [PDF]
MATEC Web of Conferences, 2019 Plastic materials can be used for various gears and gear mechanisms due to their qualities, like wear resistance when running dry, low noise, vibration damping, low inertia, low manufacturing cost, etc. However, they also expose with temperature connected problems like rapidly decreasing load, thermal expansion and accuracy of moulded gears. Therefore,
