井式渗碳炉风扇下轴承(7309)由于处在高温下工作,原在旋盖式油杯中加入钙基润滑脂(黄油),由于温度高,在离心力的作用下流下、抛出,需经常不断地加入,现加入适量二硫化钼润滑脂,很少抛出,油脂的用量大大减少。在使用中发现温度比下轴承低的上轴承(209)反而坏的次数多,拆卸 Pit carburizing fan under the bearings (7309) due to work at high temperatures, the original capping oil cup with calcium-based grease (butter), due to high temperature, the role of centrifugal force shed, thrown, need Often continue to join, now adding the appropriate amount of molybdenum disulfide grease, rarely thrown, the amount of oil greatly reduced. Found in the use of lower temperature than the lower bearing on the bearings (209) Instead of bad times, demolition
