Abstract
PURPOSE: To protect excessive surface pressure to be applied to a divided surface from occurrence in a roller bearing device having a sectional type outer holder by a method wherein a relief which continues with an easy slope in a peripheral direction is provided on the divided surface of the internal peripheral surface of the outer holder.
CONSTITUTION: A crank shaft 1 is supported rotatably in an outer holder 4 comprising an upper and a lower half part 4a, 4a through a roller bearing device in which a plurality of rollers 3 are held by a retainer 2. In this case, on the divided surface 5 on the internal peripheral surface of the outer holder 4 coming in contact with rollers 3 is provided a relief 7 which continues with a smooth surface in a peripheral direction. As for the dimension of this relief 7, about 1/2W3/2 of the pitch of the roller bearing are given to the length l in the peripheral direction and about 1/250W1/50 of the diameter of the roller bearing are given to the depth h in the radial direction. Thus, the excessive surface pressure due to the contact with the roller 3 on the part of the divided surface 5 can be prevented from occurring.
