The spindle and bearing clearance
2015-05-18 by seoer4
Between the main shaft and the bearing clearance depends on temperature, load, the minimum oil film thickness, friction loss, eccentricity of the shaft and the bearing, sealed angular contact ball bearing the shaft and the bearing surface rough degree requirements. Small bearing clearance requirements using low viscosity oil, high speed bearing high viscosity oil with large gap. Mineral oil viscosity decreases with the increase of temperature. Kinds of viscosity and thickener performance of grease and to a great extent depends on the in the preparation of base oil.
