摘要:
Revolution speeds nca, nib of rolling elements 9a, 9b are sensed by a pair of revolution speed sensors 21a, 21b. Also, a rotational speed ni of a hub 2 is sensed by a rotational speed sensor 15b. A sum “nca+ncb” or a difference “nca−nib” the revolution speeds of rolling elements 9a, 9b in double rows is calculated based on sensed signals of the revolution speed sensors 21a, 21b, and then a ratio “nca+nib/ni” or “nca−ncb/ni” of this sum or difference to the rotational speed ni is calculated. Then, the radial load or the an axial load is calculated based on the ratio “nca+ncb/ni” or “ca−nib/ni”.
