ハイポイドギヤの摩擦損失に関する研究 : 潤滑油の粘度及び表面処理の影響

抄録

Friction loss of hypoid gears was studied in order to decrease the friction loss from a view point of lubricating oils and surface treatments. The tests results showed that the viscosity affects on the friction loss very much and showed that the higher the viscosity, the lower the friction loss in both of mineral oils and synthetic oils. It was also clarified that there is a suitable viscosity to minimize the total loss of a hypoid gear unit. Especially in the case of hypoid gears used in high loads, a synthetic oil decreases the total loss of a gear unit by about 25∼30% than that of a mineral oil. Moreover it seems that the surface treatments used here have little affect on the friction loss of hypoid gears.
