Title:
転がり軸受ユニットの荷重測定装置
Document Type and Number:
Japanese Patent JP4517648
Kind Code:
B2
Abstract:
Revolution speeds nca, nib of rolling elements 9 a , 9 b are sensed by a pair of revolution speed sensors 21 a , 21 b. Also, a rotational speed ni of a hub 2 is sensed by a rotational speed sensor 15 b. A sum "nca+ncb" or a difference "nca-nib" the revolution speeds of rolling elements 9 a , 9 b in double rows is calculated based on sensed signals of the revolution speed sensors 21 a , 21 b, 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".
