Distribution of Bearing Reactions on a Rotating Shaft Supported on Multiple Journal Bearings

Résumé du livre

An analytical treatment of the problem of determining the distribution of reaction forces among multiple plain bearings supporting a shaft subjected to rotating loads is presented. The treatment differs from others in common use in that account is taken of the hydrodynamic effect of the oil film between the journals and the bearing. A relation is expressed between the eccentric running position of a journal within its bearing and the load hydraulically supported by this bearing; this relation, together with the conditions of elasticity for the shaft and the bearing supports, provides a sufficient number of equations for an analytical determination of the reactions at each bearing of a multiple-bearing system.
