摘要： A wheel bearing device is proposed which maintains long life even under high-load, high-temperature conditions. On the surfaces of inner rings and tapered rollers of a multiple-row tapered roller bearing rotatably supporting a wheel, carburized, nitrided layers are formed which contain 0.80 wt % or more carbon and have a Rockwell hardness of 58 or over with the residual aaustenite content being 25-35 vol % to improve mechanical properties and fatigue characteristics of these parts and also keep the surface layers of these parts of suitable toughness, thereby improving the life of the wheel bearing device in a high-load, high-temperature environment. Also, an annular recess is formed in the inner periphery of the outer ring at a portion between the rows of the raceways.

摘要： The end surface 2e of the press-fit portion 2c of the axle 2 is machined with high precision to serve as a reference surface for measuring the negative bearing clearance upon completion of the assembly. The inner ring 3 is press-fitted on the press-fit portion 2c of the axle 2 and is fixed in position by the nut 6 screwed on the threaded portion 2d of the axle 2. In this axle bearing assembly, the inner ring 3 abuts against the shoulder portion 2d of the axle 2 with no clearance defined therebetween, and the negative bearing clearance is assured.
摘要翻译：车轴2的压配合部分2c的端表面2e以高精度加工，用作用于在组装完成时测量负轴承间隙的参考表面。内圈3被压配合在轴2的压配合部分2c上，并通过拧在轴2的螺纹部分2d上的螺母6固定就位。在该轴承组件中，内环3邻接抵靠轴2的肩部2d，其间没有间隙，并且确保负轴承间隙。
