Geometric Aspects of Modifications of Tapered Roller Bearings

Abstract

The basic analytical relationships for construction of modified tapered roller bearings based on standard bearing type 7000 are dwelt upon. The modification consists in the replacement of rolling elements in the form of tapered rollers with a rectilinear generatrix on casters with a convex arc generatrix. The advantage of the modified-bath roller is shown by means of calculation of the permissible corner re-braid rings and the contact stresses in comparison with the standard roller bearings similar to overall dimensions.
