The invention relates to a device for reducing structure-borne noise in electric drive motors for ship drives, a rubber spring rail being arranged between at least one motor base and a foundation. The aim of the invention is to reduce the resulting structure-borne noise. This is achieved in that at least one damping element is additionally arranged between the motor base and the foundation, each damping element containing at least one dimensionally stable layer made of at least one rigid material and a layer made of at least one elastic material, wherein the layers are arranged alternately. In this manner, the damping of the structure-borne noise is improved, in principle, in all frequency bands, in particular, however, at higher frequencies (> 1 kHz) which typically occur during the clocking of power inverters or power converters. |
