Abstract
An apparatus for determining static imbalance of a test body with a receiving plate mounted gimbal-fashion in antifriction bearings with data receivers connected to the receiving plate whereby the receiving plate is supported radially, i.e., in a direction perpendicular to the plane of the gimbal axes, by antifriction bearings and axially, i.e., in the plane, by axially rigid torsion rods.
Claims5
In an apparatus for the determination of static imbalance of a test body having a receiving plate for said test body, a gimbal ring mounting said plate, means for mounting said plate for movement about two perpendicular gimbal axes in a plane and in at least two degrees of freedom, at least first and second data receivers coupled to said plate for detecting forces produced by imbalance and producing a counter force to maintain said plate in a predetermined position, the improvement wherein said ring mounting means includes a plurality of antifriction bearings along one of the gimbal axes for supporting said plate in a radial direction extending perpendicular to said plane and with respect to the gimbal axes and a plurality of axially rigid torsion bars which extend in said plane and along one of the gimbal axes to support said plate in an axial direction with respect to the gimbal axes.
