Elastomeric Sleeve Bearing Design

Abstract

<p> It is shown that the experimentally determined deflectional behavior of certain elastomer-lined sleeve bearings under static radial loads can be modeled to some extent by the compressive behavior of flat elastomeric slabs.</p> <p> An equation for the thermal bearing-bore change is developed using the conventional theory for the thermoelasticity of homogeneous cylinders. Some experimental results agree fairly well with this equation. An equation for the bore contraction due to liquid swell is developed in terms of thermoelasticity.</p> <p> Minimizing the lining thickness is recommended for minimizing both the radial deflections and the bore changes.</p> <p> An analysis is made of the frictional forces involved with the interference fit between the lining and its housing.</p> <p> Areas for further investigation are suggested.</p>
