Abstract:
A double-row self-aligning roller bearing, which is suitable for receiving an axial load and a radial load, and loads having different magnitudes acting on rollers in two rows, and achieves sufficient load capacity for the rollers that receive axial load within the constraint of dimensional standards, is provided. The double-row self-aligning roller bearing includes inner and outer rings; and rollers in two rows arranged in a bearing width direction interposed between the inner and outer rings and having lengths different from each other. The roller has an outer peripheral surface of a cross-sectional shape along a raceway surface of the outer ring having a spherical shape. Length of the longer rollers is equal to or greater than 39% of the bearing width. A ratio of contact angle of the shorter rollers and contact angle of the longer rollers is within a range of 1:4 to 1:2.

Claim (Index 11):
A double-row self-aligning roller bearing comprising\n an inner ring; an outer ring having a spherical raceway surface; and rollers in two rows arranged in a bearing width direction interposed between the inner ring and the outer ring, the rollers in two rows each having an outer peripheral surface of a cross-sectional shape along the raceway surface of the outer ring, wherein each roller in one row of the two rows has a length different from that of each roller in the other row of the two rows, the longer rollers have a contact angle \u03b8 2  larger than a contact angle \u03b8 1  of the shorter rollers, an intermediate flange is provided at a portion between the two rows of the rollers on an outer peripheral surface of the inner ring, and the intermediate flange has a center position in the bearing width direction displaced toward a side of the longer rollers from a position of a point in the bearing width direction at which lines of action defining the contact angles of the respective rows intersect.
