Title:
PRELOAD LOSS PREVENTIVE STRUCTURE OF BEARING DEVICE
Document Type and Number:
Japanese Patent JP3895456
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the preload loss by pressing and moving one inner ring of a roller bearing toward the other inner ring side by the elasticity of an elastic body even when the roller bearing is worn.
SOLUTION: A coned disk spring 10 as an elastic body is interposed between an outer side surface of a flange 8 and a nut 9 in an elastically displaced condition. The coned disk spring 10 can provide the spring force exceeding the sum of the deformation load of a plastic spacer 6 and the set preload of conical roller bearings 4,5 so that the preload of the conical roller bearings 4, 5 is not lost when the inside of the conical roller bearings 4, 5 is worn with abrasion powder, etc., of a hypoid gear 11. Thus, even when the inside of the conical roller bearings 4, 5 is worn, one inner ring 5a can be moved by the spring force of the coned disk spring 10 by following the wear, and the preload loss can be prevented. Thus, the support rigidity of the conical roller bearings 4, 5 can be ensured.
