要旨 | We have investigated the effect of grease properties and composition on the acoustic performance of bearings, from two aspects that differ from conventional practices. The fi rst of these aspects is the effect of the mechanical properties of thickeners, with a focus on the damping characteristic of thickeners. The second investigated aspect is the effect of the aggregate state of the thickeners on the nanometerscale. The results of this investigation showed that the acoustic value of a bearing can be lowered by using a thickener with a small Young’s modulus and excellent damping performance, or by increasing the expansion of the thickener using base oil for which the HSP value is low or for which the fractal index is small. |
