Abstract

Una superficie de pista (3a) de un aro externo (3) de un cojinete de rodillos cónicos (1) incluye una superficie de corona compuesta. La superficie de corona compuesta incluye una curva central (3a1), la cual es formada en una porción central en una dirección de línea de generación, y curvas de porción extrema (3a2 y 3a3), las cuales son formadas sobre ambos lados de la curva central (3a1) en la dirección de la línea de generación. La superficie de pista (3a) del aro externo (3) es sometida totalmente a superacabado. Cada una de una relación (R2/R1) de un radio de curvatura (R2) de la curva de porción extrema (3a2) del radio de curvatura (R1) de la curva central (3al) y una relación (R3/R1) de un radio de curvatura (R3) de la curva de porción extrema (3a3) al radio de curvatura (R1) se fija en 0.02 o más. Cada pendiente de las curvas de porción extrema (3a2 y 3a3) se fija en 0.07 - o menos.
