主 题:electro-damage bearings weak electrical current microbubbles
摘 要:A special bearing tester was constructed to investigate the damage behavior on the lubricated surfaces in bearings with the passage of weak electrical currents as low as^1 *** results showed that when polar glycerine was used as the lubricant,many narrow and deep pits formed on the lubricated *** contrast,when the experimental conditions under the lubrication of the nonpolar paraffin oil were close to those under the lubrication of polar glycerine oil,damages on the lubricated surfaces were *** of microbubbles in polar lubricants with the passage of electrical currents was proposed to be responsible for the observed damages on the lubricated surfaces.
