THERMOSTATTED GYROSCOPIC DEVICE Russian patent published in 2007 - IPC G01C19/00 

FIELD: gyroscopic tool-making, possible use in gyroscopic devices working under conditions of changing temperatures, pressures and accelerations.

SUBSTANCE: thermostatted gyroscopic device contains two-layered case with external and internal layers of alternating high and low heat conductivity, base with sensitive element held on it by a flange. External and internal case layers are made in form of two pairs of metallic caps with walls. Each cap of external layer is held on base, creating a closed cavity, inside which the flange of sensitive element is located. Each cap of internal layer through an appropriate heat-insulating bushing is fastened to corresponding cap of external layer. Between metallic caps of external and internal layers a gas gap is formed, and thickness of walls of metallic caps of external layer δ_k1, and thickness of metallic cap walls δ_k2 satisfies the following expression: δ_k1≥λ₂/λ_k1·H_k1R_k1/4δ₂; δ_k2≥λ₂/λ_k2·π²R² _k2/2δ₂, where λ₂, λ_k1, λ_k2 - heat conductivity coefficients for gas of materials of external and internal layers. H_k1 - height of external layer caps, R_k1, R_k2 - average radiuses of metallic caps of external and internal layers, δ₂ - average width of gas gap.

EFFECT: increased precision and simplified design.
