<p>PCT No. PCT/FI96/00209 Sec. 371 Date Oct. 8, 1997 Sec. 102(e) Date Oct. 8, 1997 PCT Filed Apr. 18, 1996 PCT Pub. No. WO96/33092 PCT Pub. Date Oct. 24, 1996The present invention relates to a mount structure for supporting an electric motor comprising a rotor and a stator frame, such an electric motor being preferably a marine engine rotating a propeller, on a ground base, such as a hull of a ship. The mount structure comprises at least one vibration damping unit, which comprises a vibration damping rail, which is arranged to receive and damp the vibration of the electric motor and which is secured to the stator frame. In order that the mount structure would also be durable in long-term use and that it would be capable of damping vibration caused by the electric motor within the frequency range considered to be disturbing in the application, spacing means are attached to the vibration damping rail in a manner known as such for securing it at a distance from the stator frame and at a distance from the ground base; and, relieving means constituting material weakening are provided in the vibration damping rail to increase the elasticity of the vibration damping rail in such a manner that the vibration damping rail yields significantly in two directions, which are at right angles to each other, one direction being parallel to the upper surface of the vibration damping rail and the other direction being transverse to the longitudinal direction of the vibration damping rail.</p> |
