The oil-film-formation between gear teeth lubricated with grease or oil lubrication is investigated by the electrical resistance technique. The grease examined is a lithium soap structure in mineral oil. The properties of grease are very similar to those of oil material. Tests are made with pairs of 31 and 35-teeth spur gears of 2.5-module, 20 deg pressure angle, and l0-mm face width. The values of loading force are changed from P_n =66. 7 kN/m to 472 kN/m in steps and the values of pitch line velocity are also changed from V= 1.59 m/s to 6.19 m/s. The observations are as follows: (1) The volume resistivity of grease is measured. (2) The relationship between the passage of time and the oil-film-formation became clear. (3) The maximum load carring capacity with grease lubrication is about 60 per cent of that with oil lubrication.
