Title:
DOUBLE ROW SELF-ALIGNING ROLLER BEARING AND PROJECTION PREVENTION JIG
Document Type and Number:
Japanese Patent JP2018115762
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a double row self-aligning roller bearing that receives an axial load and a radial load, that is suitable for being used when loads of different magnitudes are applied to two rows of rollers aligned in an axial direction, and that can prevent an unintentional aligning operation when the bearing is assembled or incorporated into the other device.SOLUTION: In a double row self-aligning roller bearing 1, rollers 4, 5 are aligned in two rows in a bearing width direction between an inner ring 2 and an outer ring 3. A raceway surface 3a of the outer ring 3 has a spherical shape. Outer peripheries of the rollers 4, 5 have a cross sectional shape along the raceway surface 3a of the outer ring 3. Any one or both of respective shapes and contact angles θ1, θ2 of the rollers 4, 5 are different from each other. Mounting holes 15, 16 that can be mounted to a projection prevention jig 17 are provided to at least one of width faces 2c, 3b of the inner ring 2 and the outer ring 3. The projection prevention jig 17 prevents width faces 2c, 2d of the inner ring 2 from projecting from width faces 3b, 3c of the outer ring 3.SELECTED DRAWING: Figure 4
