ABSTRACT:
An additional mass member22for measuring resonance of a bearing device comprises an elastic ring30having an inner periphery30alarger in diameter than the outer periphery of the outer ring24of the bearing device25and being contracted and expanded in the radial direction, and a fixed ring31having a large rigidity and fitted onto the elastic ring30. The elastic ring30is fitted to the outer ring20, and then the fixed ring31is fitted to the elastic ring30to push the elastic ring30in the radial direction, so as to contract the inner periphery30aof the elastic ring30, so that the additional mass member22is fixed to the bearing device21, whereby the resonance frequency of the bearing device having a double row of bearings can be measured precisely and readily.
