Introduction to the miniature tapered roller bearing

Single row circular cone roller bearings can withstand the big radial direction and axial load or only carry thrust load. By the inner and outer raceway contact Angle is different, make between roller and guard in a contact force. Due to the relatively large sliding friction on the rim, without plus special cooling and lubrication condition, the taper roller bearing is not suitable for high-speed operation. Terms of tapered roller bearing and other how many there are some different roller bearing, which circle is called 'cone', the outer ring is called the 'cup'. As shown in figure 1. 44, little different because of the large bear axial load, tapered roller bearing contact Angle is small. Because of tapered roller bearing is separable, so its general installation in pairs, and mutual adjustment, as shown in figure 1. 45. In order to improve the bearing radial load capacity, while eliminating due to long distance between two sets of bearing axial adjustment problems, as shown in figure 1. 46, tapered roller bearing combination for the double row bearings. Figure 1. 47 is a set of typical railway passenger car wheels with double row circular cone roller bearings. Double row bearings can also be combined into four row roller bearing to withstand the bigger radial direction load as in roll application. Figure 1. 48 for whole sealing fluid of four row circular cone of miniature bearing. Figure 143 have separable integral inner circle and cylindrical roller bearing outer ring and similar, tapered roller or roll way too often. Cage, roller components of single child bearing cone play often with crown to eliminate the stress concentration of the roller ends.
