Paper Title:
Influences of Nano-Silica on Friction and Noise Properties of Urea Grease
  Abstract

Tribological properties of the urea grease containing nano-silica were investigated with a four-ball tester, and its noise characteristics were evaluated with a BVT-1 bearing vibration tester. The results showed that the nano-silica has good effects on friction and wear resistances, the urea grease with 3% nano-silica has the least value of friction coefficient, and the urea grease with 2% nano-silica showed the best wear resistance. A proper amount of nano-silica can decrease the noise of the urea grease, and when lubricated by the grease with 1% nano-silica, the bearing achieved its lowest noise level as well as the best velocity values of both intermediate and high frequencies.
