There are oil bath lubrication and shaft core lubrication as methods for appropriately supplying transmission oil, but this time we focused on shaft core lubrication. In shaft core lubrication, due to the structure in which oil flows through the rotating lubrication path, centrifugal force becomes dominant and agitation occurs, making it impossible to supply the desired lubrication. In order to solve this problem, the effects of supply flow rate, rotation speed, and TP shape on the lubrication flow rate were investigated.At present, it has been found that the lubrication flow rate becomes uniform by increasing the supply flow rate. As for the TP shape, it was obtained that the lubrication as intended was possible by increasing the number of holes rather than increasing the hole diameter.Furthermore, by visualizing and measuring the oil film distribution, the relationship between the lubrication flow rate and the influencing factors was clarified.
