Title:
自律分散式転がり軸受
Document Type and Number:
Japanese Patent JP7004396
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an autonomous dispersion-type rolling bearing which can use a common inner ring (or outer ring) irrespective of a direction of an inside diameter (or outer ring) and the necessity for the external supply of a lubricant, in the autonomous dispersion-type rolling bearing such as a deep groove ball bearing which can receive axial loads in both directions.SOLUTION: Rolling-body insertion holes which allow the penetration of rolling bodies penetrating in a normal direction are fixed at a raceway surface of an inner ring or a raceway surface of an outer ring, and the holes are closed by plugs after the insertion of the rolling bodies between the raceway surfaces of the inner ring and the outer ring from the rolling-body insertion holes. A replenishment path of a lubricant and a contact point change path for dispersing the rolling bodies may be formed in the plugs. The plugs hinder the continuity of a raceway, however, in the autonomous dispersion-type rolling bearing having the plugs at an inner ring, since the rolling bodies do not contact with the inner ring in a non-load region, a problem does not occur.SELECTED DRAWING: Figure 1
