PROCEDURE DETERMINING MOMENT MISALIGNMENT OF BODIES OF REVOLUTION

摘要

FIELD: measurement technology. SUBSTANCE: procedure is intended for determination of moment misalignment of bodies of revolution with nonmaterialized axis of rotation and bodies having no clear base attachment surfaces. For realization of procedure body is set in gimbal suspension with horizontal axes so that suspension axes coincide with construction axes of body. Suspension is rotated with reference to vertical axis and maximum deviation of body from initial position is measured and its value is used to evaluate moment misalignment of body. Body is set in internal frame of gimbal suspension manufactured in the form of casing so that longitudinal axis of body coincide with vertical axis of suspension and construction axes of set of casing-body coincide with construction axes of body. Casing with body and external frame of gimbal suspension are interconnected with the use of torsion bars and are installed in housing by means of torsion bars. EFFECT: improved sensitivity while measuring misalignment of bodies having no base attachment surfaces, simplified procedure measuring misalignment. 1 cl, 1 dwg
