Title:
DOUBLE ROW ROLLING BEARING DEVICE WITH PRELOAD
Document Type and Number:
Japanese Patent JP3419053
Kind Code:
B2
Abstract:
PURPOSE: To prevent distortion of an inner ring raceway accompanying fitting the inner ring outside a shaft so as to obtain high bearing accuracy.
CONSTITUTION: A small diameter part 31 and a large diameter part 32 are formed on the inner circumferential face of an inner ring 27 putting a recessed groove 30 there between. An inner ring raceway 29 is formed on the outer circumference of the large diameter part 32. The inner ring 27 is fitted outside a shaft 26 at the small diameter part 31. Even if the small diameter part 31 is distorted accompanying outside fitting, the distortion hardly reaches the large diameter part 32, and the inner ring raceway 29 is hardly distorted. Consequently, high bearing accuracy can be obtained.
