low temperatures, rotary bearings in oil should be timely oil changes.Under conditions of a clear premise, in the selection of varieties of oil is also a technology live.Analysis of ways in choosing a suitable bearing lubricants. If the bearing lubricant selected properly, the viscosity of oil is not enough, a thin film is formed over the still cause greater friction between the shaft and the tile.When rolling circle near the Rotary Kiln at the feed mill to discuss thin, will produce local temperature radiation into the bearing, the lubricant becomes low stiffness, lack of good lubricating thin film between the shaft and tile. At this point, you should immediately replace higher strength lubricants.There are long Rotary kiln playing slow time, speed and low, the oil inside scoop riding wheel bearing oil belt is too small, can not meet the need for lubrication between the shaft and the tile.In this case, a temporary artificial refueling, and timely contact with the workers to see the fire, so that the Rotary kiln speed control 20r / h or more.When the oil spoon bearing failure or automatic sump blockage or oil is too low, resulting in reduced lubrication, it should be repaired or add new oil. Bearing in starvation state.At this point, it is timely winter oil change.And remove the heat shield on the bearings, bearing Rotary kiln increased radiation temperature.When rolling circle near the Rotary kiln at the feed mill to discuss thin, will produce local temperature radiation into the bearing, the lubricant becomes low stiffness, lack of good lubricating thin film between the shaft and tile.
