LUBRICATION DEVICE OF ROLLING BEARING

摘要

PROBLEM TO BE SOLVED: To provide a lubrication device of a rolling bearing capable of efficiently cooling the bearing by a simple structure and enabling a high-speed operation without increasing a power loss. SOLUTION: This lubrication device of the rolling bearing lubricates the rolling bearing by discharging the lubrication oil from a lubrication oil lead-in member 7 adjacent to an outer ring 3 into the rolling bearing 1. A lubrication oil inflow part 17 of the lubrication oil lead-in member 7 and a discharge port 8 communicating with the inflow part 17 through a communication passage 9 and discharging the lubrication oil to the rolling bearing 1 are disposed in the rolling bearing 1 so as to be displaced from each other in the circumferential direction.
