The invention provides a preload inspection method capable of calculating a preload value with higher precision. Further provided is a preload inspection method capable of determining, with higher accuracy, whether the preload state is qualified or not. A wheel bearing device (1) is provided with: an outer member (2) having outer raceway surfaces (2c, 2d); an inner member (3) having inner raceway surfaces (3c, 3d); and rolling bodies (4, 5), the preload inspection method for the wheel bearing device (1) being provided with: a power calculation step (S5) in which the outer member (2) or the inner member (3) is rotated relative to each other and the power (P) is calculated; a preload value calculation step (S6) for calculating a preload value (F2) on the basis of the power (P) calculated in the power calculation step (S5); and a qualification determination step (S7) for determining qualification on the basis of whether or not the preload value (F2) calculated in the preload value calculation step (S6) is within the allowable range (R).
本发明提供能够更高精度地算出预压载荷值的预压检查方法。进一步,提供能够更高精度地判定预压状态的合格与否的预压检查方法。车轮用轴承装置(1)具备:具有外侧轨道面(2c、2d)的外侧构件(2);具有内侧轨道面(3c、3d)的内侧构件(3);以及滚动体(4、5),车轮用轴承装置(1)的预压检查方法具备:功率算出工序(S5),使外侧构件(2)或内侧构件(3)相对地旋转而算出功率(P);预压载荷值算出工序(S6),基于在功率算出工序(S5)中算出的功率(P)而算出预压载荷值(F2);以及合格与否判定工序(S7),根据在预压载荷值算出工序(S6)中算出的预压载荷值(F2)是否处于允许范围(R)内来判定合格与否。
