抄録

In the previous paper of the author, the rolling friction under line contact and the lifetime of the rolling cylindrical body were discussed. In the present paper the experimental results of rolling friction in the case of point contact and the lifetime of the rolling body under static load and oil lubrication are presented on the basis of the information of the previous paper. In the present paper the characteristics of rolling friction in both cases of line and point contact is also reported by use of #60 spindle oil and jet fuel oil (JP-4), respectively. From the present study the following conclusions have been obtained;<br>(1) The characteristics of friction under point contact and the lifetime of the rolling body are nearly the same as those under line contact. The strength of the oil film and the maximum pressure of rolling fatigue limit under point contact are larger than those under line contact.<br>(2) In the case of point contact, there is small difference between the characteristics of rolling friction by use of #60 spindle oil and that of jet fuel oil, but larger difference in the case of line contact.
