Abstract
A vibration isolation system for a cover mountable on a vibratable engine includes a plurality of resilient grommets positioned about a plurality of stripper bolts which are inserted into the cover and through a resilient sealing gasket to threadedly secure the cover to the engine. The grommet and gasket have spring rates within a predetermined range of each other to provide maximum isolation of the cover from the engine.
Claims54
A vibration isolation system comprising:
- base means;
- cover means having an outer perimeter for mounting on the base means to cover the base means;
- securing means having head means for securing the cover means on the base means;
- a plurality of resilient isolating means disposed around the securing means and between the head means and the cover means having predetermined spring rates therebetween;
- and resilient isolating sealing material means substantially paralleling the outer perimeter of the cover means disposed between the cover means and the base means having a predetermined spring rate therebetween which is equal to or less than twice the sum of the predetermined spring rates of the plurality of resilient isolating means.
