ROLLING BEARING DAMPING DESIGN OF SANDWICH OUTER RING WITH STEEL FACES AND POLYMER COMPOSITE MATERIAL CORE

The damping function of the sandwich outer ring of rolling bearings was studied according to polymer composite material delayed strain response to stress under the rolling bearing vibration. This paper also presents the results of noise test to this kind of rolling bearings. The conclusion is obtained that this kind of structure has good vibration absorption and noise abatement. This study will furnish the theoretical basis for design and application in engineering.
