INCREASING THE LOAD CAPACITY OF ANTIFRICTION BEARINGS (O GORDULOCSAPAGYAK TERHELHETOSEGENEK NOVELESE),

Abstract

The uneven distribution of stress on the contact surface of cylindrical roller bearings has been studied. It was theoretically shown that stress is greatest on the edges of the contact surface. A formula was found for the shape of the roller which would secure optimal carrying ability. A roller profile was designed in theory and tested in practice by the photoelasticity method and the deformation and durability tests. As a result, a new, precalculated roller shape makes it possible to install smaller bearings with high carrying ability and great durability whereas, formerly only large roller bearings could be used. This means lower weight and a reduction in cost and size. (Author)
