ABSTRACT:
Bolted mounting assemblies for use between two mounted components wherein one of the components experiences vibration typically use rubber shock absorbers to dampen the vibration transfer between the components. The rubber shock absorbers are expensive and complicated to manufacture and are limited in flexibility control. The present invention overcomes this and other problems by providing an adhesive with damping capabilities between washers in a bolt assembly. The bolt assembly is used to mount first and second components with the washers therebetween. The adhesive is spaced a predetermined distance from a longitudinal axis of a bolt and has a non-uniform thickness which increases as the distance from the longitudinal axis increases to provide protection from bending loads about the axis. The washers with adhesive form a washer assembly with damping and flexibility characteristics controlled through variations in the design. The washer assembly provides a simple, inexpensive shock absorber between two components which experience vibration to substantially eliminate vibration transfer therebetween.
