摘要:
In a bearing device in which a free end of a shaft body to which a rolling bearing is mounted is bent outward in its radial direction into a shape to be pushed against an end face of an inner ring of the rolling bearing so as to prevent the rolling bearing from falling out, a raceway surface of the inner ring of the rolling bearing is subjected to hardening treatment, and other portion of the inner ring is made of raw material which is not hardened. With this arrangement, the caulked portion formed by the caulking plastically deforms the relatively soft inner peripheral corner of the inner ring and as a result, the caulked portion and the inner peripheral corner are adhered to each other strongly.

A bearing device comprising a shaft body having an axially cylindrical portion in a free end side thereof and a rolling bearing fitted around an outer peripheral surface of the shaft body, wherein the cylindrical portion is bent and deformed radially outward by a rolling caulking to be caulked thereby on an outer end face of an inner ring of the rolling bearing. An inner peripheral surface of the cylindrical portion is formed by a turning work, and a residual stress left in a surface layer of the inner peripheral surface of the cylindrical portion by the turning work is set to a value capable of restraining a crack generation ratio in the inner peripheral surface to less than a predetermined rate, desirably to not more than 5 kgf/mm2.

摘要:
There is disclosed a bearing device in which a double row angular contact ball bearing is mounted to an outer periphery of a hub wheel, a caulking portion is bent diametrically outward and caulked on an end face of an inner ring of a bearing, thereby preventing the bearing from falling out from the bearing device and to applying a pre-load to the bearing. An axially outer edge of the inner ring is chamfered roundly, the caulking portion is provided at its shaft end with a small-diameter portion, and a starting point of the small-diameter portion is located closer to an axially central portion than a chamfer-starting point of the axially outer edge of the inner ring.
摘要:
A vehicle-use bearing apparatus including a hub wheel formed of steel material to which a wheel is mounted and a rolling bearing mounted to an outer periphery of the hub wheel. An end portion of the hub wheel is expanded radially outward toward an inner ring provided to the rolling bearing to be formed into a caulked portion and a percentage of sulfur content is adjusted to be 0.020% by weight or less in steel material of which the caulked portion is formed.

摘要:
The present invention relates to an axial force controlling method for controlling an axial force applied to a rolling bearing in a bearing apparatus having a shaft body, the rolling bearing being mounted to the shaft body such that the rolling bearing fits an outside of the shaft body, and the bearing apparatus.
摘要:
This wheel speed detector is constructed of a magnetic sensor and a magnetic ring and is integrated with the inside of a seal device. The magnetic ring constitutes a part (core bar) of the seal device. This arrangement can enable the compacting and reduction in the number of components and improve space saving and assembling workability.
摘要:
A wheel speed detector for detecting a relative rotating speed between an outer ring and an inner ring by means of a magnetic sensor in association with a magnetic ring. A stationary seal member is fixed to the stationary ring and a rotatable seal member is fixed to the rotatable ring. The seal members engage to seal a gap between the inner ring and the outer ring. The magnetic sensor is fixed to a radial inner surface of the stationary seal member and the magnetic ring is fixed to a radial outer or a radial inner surface of the rotatable seal member and surfaces of the magnetic ring other than that fixed to the radial inner surface of the rotatable seal member are covered with a seal lip.
