Description
(a)低温(−75℃)から高温(250℃:微粉末の酸化温度の低い二硫化モリブデンでも酸化しない温度)の幅広い使用温度での潤滑が可能である。
(b)オイル、グリースによる潤滑に比べて、潤滑性微小粉体による潤滑は発熱が少ない。例えば、本発明者等の実験によれば、グリース潤滑時の波動歯車装置の内部温度に比べて、潤滑性微小粉体による潤滑の場合には内部温度が約15〜18℃低いことが確認された。
(c)オイル、グリースによる潤滑では静荷重時に接触面からの潤滑剤の抽出が生じるが、潤滑性微小粉体による潤滑では静荷重による接触面からの潤滑剤の抽出が無い。したがって、停止期間が長く、低頻度の動作時にも接触部が確実に潤滑できる。
(d)潤滑性微小粉体による潤滑は、低速入力回転の場合にも対応可能である。
