    摘要: The method for calculating rotational torque between inner and outer rings of a four point contact ball bearing assembly includes an individual torque calculation step for calculating the rotational torque for each of rolling elements and a total sum calculation step for determining the rotational torque. In the individual torque calculation step, data on a contact condition representative of the extent of approximation to the two point contact state or four point contact state is used. For the contact condition data, the four point contact ratio Cf, which is the ratio of surface pressure of one of respective maximum contact pressures P1 and P2 between two partial raceways in an inner ring or outer ring, which one is higher than the other of the maximum contact pressures P1 and P2, relative to a surface pressure of the other of the maximum contact pressures, is used.
