Document Type and Number:
Japanese Patent JP2017057950
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a double row self-aligning roller bearing that in a case where different loads act on right and left rows, breaks down the loads at a ratio based on load capacities rollers of the right and left rows have, to thereby enable a large load capacity to be secured in the whole bearing, and a substantial life of the whole bearing to be improved.SOLUTION: A double row self-aligning roller bearing 1 is provided with right and left rows of rollers 4, 5 between an inner ring 2 and an outer ring 3. A raceway surface 3a of the outer ring 3 is formed into a spherical shape, and outer peripheral surfaces of the rollers 4, 5 have a cross sectional form along the raceway 3a of the outer ring 3. For the rollers 4, 5, a length L1 of the left roller 4 and a length L2 of the right roller 5 are different from each other, and the number of left rollers 4 and the number of right rollers 5 are different from each other.SELECTED DRAWING: Figure 1
