Adjusting the life is based on various environmental factors, such as operating temperature, eccentricity, bearing area, lubrication and stress levels. Its formula is: L 10 is the sample life (hours) Ai is the environmental coefficient The results show that the adjustment life of the double row tapered roller bearing plus cylindrical roller bearing is longer than that of the spherical roller bearing scheme. Even if the double-row tapered roller bearing has a lower rated capacity than the spherical roller bearing, the tapered roller bearing performs better than the spherical roller bearing because it can be pre-tensioned. Preloading improves the load distribution and load bearing area between the two rows of rollers. Shaft deformation Figure 4 shows the relationship between the radial deformation and position of the spindle. Figure 4: Spindle deformation (English explanation in the picture: Shaft deflection- condition 1 - Shaft deformation - Case 1; model with tapered roller bearing - Model with tapered roller bearing; model with spherical roller bearing - Model with spherical roller bearing; location – position) Previous page next page Storm Valve,Closed Vertical Storm Valve,Anti Wave Valve,Closed Vertical Wave Valve Jiangsu Hida Marine Valve Co., Ltd , https://www.haidavalve.com
