In the fastening of noise-generating machines, particularly centrifuges, the noise in the form of structure-borne noise is often transmitted to other parts of the plant. In order to largely to prevent this, separating joints (16, 17) filled with structure-borne noise deadening material are placed between the fastening parts (14, 15) and the section beams (11, 11') to which the centrifuge with its housing is fastened.

Machine having devices to reduce transmissions of structure-borne noise

The material settling on the inside of the centrifuge drum during operation of centrifuges causes imbalances on account of the unavoidable nonuniform mass distribution, which imbalances lead to vibrations and the associated high level of solid-borne sound and bearing wear. The centrifuge drum shaft (15) is supported by an active (variable pressure) hydraulic bearing support (10) that is relatively simple in design and inexpensive to manufacture for this centrifuge application.
