Thrust bearing

摘要

A thrust bearing or tapered-land thrust bearing including a plurality of lubricant feeding nozzle holes. At least one of the nozzle holes is disposed in close proximity to the leading edge of a tapered surface of a bearing surface of the thrust bearing. By this arrangement, hot oil carryover can be minimized and the temperatures of a film of lubricant formed between the bearing surface and a thrust collar positioned there-against and a bearing body of the thrust bearing can be reduced. Thus the thrust bearing can withstand uses under high speed and high load conditions.
