    Abstract: PROBLEM TO BE SOLVED: To provide a calculation method, device and program capable of acquiring a value of accurate rotation torque taking influence caused by variations in a contact state into consideration, which is a problem particular to a four-point contact ball bearing. SOLUTION: A method which calculates rotation torque acting between inner and outer rings of a four-point contact ball bearing, includes an individual torque calculation process (V1) for calculating rotation torque T for every rolling element, and a total sum calculation process (V2) for acquiring the sum of the rotation torque T of all rolling elements to be taken as rotation torque acting between the inner and outer rings. In the individual torque calculation process, the calculation is performed by utilizing information whether a contact state is close to a two-point contact state or a four-point contact state. A four-contact ratio C f which is a ratio of surface pressure of smaller surface pressure to larger surface pressure with respect to respective maximum contact pressures P 1 , P 2 of the respective two raceway surfaces and rolling elements of the inner ring, is employed as the contact state.

    Abstract: PROBLEM TO BE SOLVED: To provide a roller bearing capable of effectively suppress the skew of rollers without generating edge load at both ends of the rollers. SOLUTION: A recessed crowning with a radius of curvature ρ 1 larger than a radius of curvature ρ 0 of a projecting crowning on the rolling surface 3a of the rollers 3 is added to the raceway surface 1a of an outer ring 1, and a projecting crowning is added to the raceway surface 2a of an inner ring 2. Therefore, the contact pressure of the outer ring 1 having an action to geometrically suppress the skew of the rollers 3 on the raceway surface 1a of the outer ring 1 is increased at both ends of the rollers 3 in the axial direction to restrain the rollers 3. The contact pressure of the inner ring 2 having no action to geometrically suppress the skew of the rollers 3 on the raceway surface 2a of the inner ring 2 is lowered at both ends of the rollers 3 in the axial direction to prevent a large tilt moment from acting on the rollers 3 from the raceway surface 2a of the inner ring 2. Consequently, the skew of the rollers 3 can be effectively suppressed without producing edge load at both ends of the rollers 3. COPYRIGHT: (C)2007,JPO&INPIT
