A112 ねじ圧縮機のすべり軸受(第7報) : スラスト軸受の潤滑溝を、軸受配置とランナ配置との冷却効率について(OS-1 環境調和型冷凍空調システムI)
詳細
In this report, cooling effectiveness of sliding thrust bearing with forced lubrication system for screw compressor is studied. Lubricant heat generated at bearing surface is partly mixed with and dissipated by fresh lubricants through bearing grooves and the rest is carried over to the next bearing surface. Effect of the bearing groove arrangement of the thrust bearing on cooling effectiveness is experimentally investigated. As the results cooling effectiveness of the bearing with grooves on runner is superior than that with grooves on pad, which results in lower bearing temperature. Cooling effectiveness of the bearing with grooves on runner is found to be aborts 80%.
