Abstract
Dynamic displacements of a crankshaft journal in its main bearing under various load and speed conditions were measured in a Petters AV1 diesel engine, the shaft loci within the bearing clearance circle being displayed by an a.c. bridge system comprising inductance transducers. Analysis of the results in terms of dynamic hydro-dynamic lubrication theory demonstrates the importance of shaft-housing deflections under high impulsive loading. With due allowance for such deflections, experimental results are in fair agreement with data calculated from Ocvirk's narrow bearing theory.This publication has 0 references indexed in Scilit:
