Abstract

We carried out a pitting test and a scoring test of spur gears lubricated with three biodegradable oils, a mineral hydraulic oil and a turbine oil. Then, we measured the surface temperature on the gear tooth by a dynamic thermocouple, and observed the lubrication condition between meshing teeth by the electrical resistance method to investigate the effect of the biodegradable oil on the tooth surface failure of spur gear. It was found that the pitting resistances of biodegradable oils are higher than that of the mineral hydraulic oil and lower than that of the turbine oil, and that biodegradable oils have higher scoring resistance than the mineral hydraulic oil and the turbine oil.
