As an important inertial instrument widely used in aeronautic, astronautic and navigation, high precision gyroscope has supreme requirements for the assembly process. The components structure stability is the key problem for the high precision gyroscope manufacturing process. The assembly stress is the main factor affecting the structure stability. Therefor the assembly stress control technology become one of the most interesting research directions for the high precision gyroscope. An errors model is established for the gyroscope based on its structure character and the errors sources. The relationship between the structure stability of components and the precision of the gyroscope is also analysed. Threaded fastening and adhesive bonding technologies for the gyroscope are studied, and one method of an assembly stress control for gyroscope is brought forward.
