Arrangement for supporting vertical-axis machine housing

摘要

A support structure for a component of a vertical-axis machine such as its housing or a bearing spider thereof and particularly a rotary electrical machine which is expandable under operating conditions due to generation of heat. In order to maintain a stabilized concentric expansion of the component during thermal expansion the supporting structure is characterized by a system of plate springs arranged in substantially vertical planes and wherein the respective planes in which the springs are located lie tangent to the surface of at least one imaginary cylinder co-axial with the axis of the machine component, the radius of the cylinder being smaller than the mean radial distance of the plate springs from the axis of the machine component.
