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 ...

Analysis of Elastohydrodynamic Lubrication for Steel-polymer Spur Gear Pairs

Jixie chuandong
Polymer gears have the advantages of good self-lubrication and low production cost. Polymer gears are susceptible to pitting failure in transmission due to load, lubrication, etc. Metal-polymer gears' pairs have a longer service life than polymer-polymer
