Abstract:
1. A method of optimizing angular orientation of rolling contact surfaces in a bearing having an inner ring and an outer ring on which the rolling contact surfaces are respectively provided and tapered rollers received therebetween, the bearing being received to a shaft and held thereto by carrying out of a caulking operation in which an end of the shaft is deformed outwardly so as to be caulked to an outer end surface of the inner ring, the method comprising: determining an angle of the rolling contact surface of the outer ring at which extended lines of the respective rolling contact surfaces of the inner and outer rings intersect at a common point at a rotational axis of the shaft prior to the caulking operation; obtaining an adjusted angle for the rolling contact surface of the outer ring by adding a fluctuation angle of the rolling contact surface of said inner ring due to the caulking operation to the angle of the rolling contact surface of the outer ring; and orienting the rolling contact surface of the outer ring at the adjusted angle relative to the rotational axis prior to performing the caulking operation.
