The limiting load for scoring and frictional loss of hypoid gears were investigated. Four kinds of hypoid gears with various offsets were chosen for our research. Further various kinds of lubricating oils were used for our experiments, that is, turbine oil, gear oil with additive of Zn-P type, gear oil with additive of S-P type and hypoid gear oil of GL 5. The results of these hypoid gears were compared with those of the spur gears. Some new tendencies of load carrying characteristics of hypoid gears were discovered. Limiting load for scoring expressed with Hertzian pressure decreases with increasing offset. Further limiting load for scoring expressed with Hertzian pressure is dependent upon specific sliding along the line of contact on the tooth surface. However the frictional loss grade is not dependent upon those factors but dependent upon value of sliding velocity or revolutional speed. These new results are summarized by using empirical formulas.
