FIELD: measurement technology. ^ SUBSTANCE: turning table can be used in test equipment for certifying inertial data converters. Turning table has platform mounted onto shaft, tracking system provided with actuating mechanism connected with shaft. Tracking system has device for presetting angular speed, amplifier and feedback unit. Shaft is made in such a way to place platform inside thermal chamber. Temperature screen is made onto part of shaft to cross hole in wall of thermal chamber. Temperature screen has bushing made of thermo-insulating material. Bushing is placed onto shaft. N rings made of thermo-insulating material and n-1 to n+1 ring-shaped gaskets are mounted onto bushing. Gaskets are made of fluoroplastic film with thickness of 0,1-0,2 mm. Rings and gaskets are disposed in series in the direction of longitudinal axis of shaft in such a way that one gasket divides two rings disposed close to each other. External diameter of gasket relates to its internal diameter as 1,05-1,15. Size of ring in the direction of longitudinal axis of shaft relates to thickness of gasket as factor of 20-50. Metal radiator is mounted onto shaft at external part of thermal chamber. Radiator has ring-shaped ribs disposed concentrically to longitudinal axis of shaft. The rings are oriented to direction being opposite to wall of thermal chamber. ^ EFFECT: widened functional abilities. ^ 4 dwg
