Title:
CONICAL ROLLER BEARING
Document Type and Number:
Japanese Patent JP2016153664
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a conical roller bearing for a planetary speed reducer, which prevents lubrication failure of a guided surface, prevents abrasion, prevents a holder from inclining by centrifugal force, and can impart preload.SOLUTION: A holder guide surface (raceway surface 9) for guiding a holder 5 to a radial direction is provided only on the inner periphery of an outer ring 2, and in the holder 5, a guided surface 10 guided to the holder guide surface (raceway surface 9) is formed in at least one of a pillar part 8 and both annular rings 6, 7. Consequently, the vicinity of the axial center of the holder 5 and both sides in the axial direction are guided to prevent inclination with centrifugal force, and both side surfaces of the outer ring 2 can be utilized for preload.SELECTED DRAWING: Figure 1
