While the basic analysis of the intermittent lubrication system was theoretically treated in the 1st report, in this report the design theory of its system, including a hydrostatic thrust bearing, is examined with some experiments.By observing the experiments and simulating the dynamic behavior of the system by analog computer, the results are obtained as follows.(1) Oil film thickness, power loss, and temperature rise are systematically defined by dimensionless quantities such as hydrostatic thrust parameter, power loss parameter, linear size factor.(2) Oil film thickness is automatically regulated by the intermittent lubrication system with variable impedance, causing an improved performance of the oil distributing surfaces.(3) Remarkable temperature rise is observed in high speed operation at low temperature.(4) The influence of the speed and the resistance coefficient on the oil film thickness and dynamic pressure are simulated by analog computer with pretty good accuracy.
