The gyro moment "S" of the cylindrical roller 6 is taken to be equal to or larger than the sum of the moment "U" which occurs due to dynamic unbalance of the cylindrical rollers, and the moment "C" which occurs due to fluctuation on the skew angle of the cylindrical rollers, that is, S / U + C. At the same time, when the cylindrical rollers are skewed, so that the end faces of the cylindrical rollers come in rubbing contact with the inner surfaces of the rims, the product Q Ò V of the force "Q" which is applied in the direction of pressure between the end faces of the cylindrical rollers 6 and the inner surfaces of the rims 8 at the points of sliding contact due to the moments "S", "U" and "C", and the sliding velocity "V" at the point of sliding contact is 60 kgf Ò m/s or less. |
