摘要： 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.

摘要： PURPOSE:To make improvements in the operating characteristic of a rolling bearing at a low temperature range and to promote the secureness of anticreep and rotative accuracy in this rolling bearing at a high temperature range by enabling it to reduce a variation attending on a temperature change in the fitting clearance of this bearing in relation to a housing. CONSTITUTION:In a structure supporting a turning shaft 3 on a boss (equivalent to a housing of a request item) 6 of a fan 4 via a rolling bearing 7, a bearing fitting surface 8 of the boss 6 is reinforced with a fiber, and thereby a linear expansion coefficient on this bearing fitting surface 8 is set to be an intermediate value between the linear expansion coefficient of an aluminum alloy or the base material and the linear expansion coefficient of ferrous metal or a bearing ring material of the rolling bearing 7. With this constitution, a contracting degree of the bearing fitting surface 8 attendant upon temperature change is made so as to be controlled to smallness.
