LUBRICATING GREASE AND MOTOR WITH SPEED-REDUCING MECHANISM

摘要

PROBLEM TO BE SOLVED: To obtain a lubricating grease capable of stably exhibiting its excellent lubricating characteristics even if used between sliding members subjected to high contact pressure. SOLUTION: This lubricating grease is obtained by adding >=10 wt.% of PE beads each 5-40μm in diameter as solid lubricant to a base grease. The lubricating grease can exhibit its excellent lubricating characteristics even if used between sliding members (between a worm 4b and a worm wheel 10) subjected to mutual contact pressure exceeding 0.5 kgf/mm2 since the mutual coefficient of static friction is stably suppressed to low levels.
