Dynamoelectric machine with rockable bearing supports

摘要

A dynamoelectric machine has rockable pedestal journal members to support the rotor. The rockable journal members ride on spherical buttons to permit movement. A lower bearing shell supports the rockable members within an outer housing. A key is provided in channels between the lower bearing shell and the outer housing which may be easily removed. Shims may be placed on top of the key as desired to effect positioning of the rotor.
