Method of supplying a lubricant to a rolling bearing of a high-speed spindle

摘要

A method of supplying a lubricant to a roller bearing of a high-speed spindle includes pressuring the lubricant in a pump chamber and discharging the pressurized lubricant within the pump chamber from the nozzle. Also, the method includes bringing a fine quantity of lubricant discharged from the nozzle into direct contact with a lubricating surface of a rotary body of the roller bearing.
