ABSTRACT:
The invention is concerned with the reduction of the vibration transmitted from a mechanism having at least one element rotating at a fundamental frequency and one or more cyclically displaceable further elements connected to said rotating element, and in which the displacements of said further elements produce an aggregate cyclic linear exciting force of fundamental frequency and harmonics thereof acting on the same line. To prevent transmission of vibrations produced by said exciting force from the mechanism to its support means, the mechanism is constrained to prevent all degrees of freedom of movement relative to the support means except for movement under the influence of said linear exciting force which is thereby isolated from the support means. The mechanism also has balancing means integral with or attached to said rotating element for balancing any rotating force produced at said fundamental frequency. Low rate resilient suspension means and damping means may also be connected between the mechanism and the support means.
