Abstract
A high speed gear box including ribs, gears with holes, and oil channels configured to divide and distribute lubricating oil and contacting the lubricating oil with a high speed gear box housing wall. The high speed gear box housing and gear box cover have lubricating oil channel which supply lubricants to bearings. Output gears have holes which circulate oil throughout the high speed gear box. As lubricating oil is continuously circulated at locations which may create friction, the thermal energy, which is generated by high speed rotation of gears, shafts, and bearings is absorbed by cooling oil and transferred to housings, latent heat is dissipated to atmosphere through housing wall. This solves the overheating problem of electric high speed gear box.
