Multirow ball or roller bearing or combined ball/roller bearing

摘要

A large antifriction bearing, wherein one of the inner ring parts or the outer ring parts are provided with axially extending, wide toothing. At least one or both of the inner and outer ring parts is divided into cooperating parts through the axis of the bearing. Each set of axially adjacent cooperating ring parts is in turn divided into circumferential segments, and the segments are circumferentially offset. The offset axially neighboring segments of cooperating ring parts are fastened together. One of the rings has its ring parts shaped for defining a U-shape in cross-section. The other ring has its ring parts shaped for defining a projecting portion that projects between the arms of the U-shape. The rolling elements of the bearing are disposed between the insides of the arms of the U-shaped part and the projection from the other part. Preferably the ring part having the teeth is U-shaped, although the other ring part may be U-shaped. Appropriate openings and recesses are defined in cooperating ring segments, and particularly may be defined in the facing surfaces of ring segments, so that the openings or recesses are aligned and connecting bolts or pins are disposed in the aligned openings or recesses.
