Abstract: 

We consider the possibility to increase the assessment accuracy of dynamic loads operating in gear engagement for drive gearbox of spacecraft actuating mechanisms. To improve dynamic loads data assessment on the design stage of the following devices: solar panels, antennas, various manipulators etc., the application of dynamic ratio is substantiated and the application of the dynamic loads increasing ratio is proposed and substantiated. Comprehensive diagrams of dynamic load levels due to the proposed and basic methods are obtained.

Keywords: drive of actuating mechanisms, dynamic load, spacecraft
