摘要：
The static equilibrium equation of the system is fulfilled based on the stress state of each gear with coaxial six⁃branch twisted herringbone gear transmission system as the research object.Considering the manufacturing error, installation error and dislocation caused by input and output wheel floating, the existence of error is analyzed based on the theory of equivalent meshing error.The system deformation coordination equation is established according to the closed characteristics of system power.The static load coefficient and branch static load coefficient of coaxial six⁃branch herringbone gear transmission system are obtained by examples.The results showed that when there was no error or the gear error was the same constant value, the static meshing force of the first grade gear was 1.773×105 N and the second grade gear was 3.673×105 N.The system has good static load⁃sharing performance and the system branch static load⁃sharing coefficient was 1, and the closed loop error of the system can be eliminated from each other.When the amplitude of manufacturing and installation error was 50 μm at the same time, the variation amplitude of branch static load coefficient under manufacturing error was larger than that under installation error, and it can be seen that the manufacturing error had a great influence on the static load performance of the system.When the amplitude of partial torsion and parallel error was 50 μm at the same time, the static load⁃sharing per⁃formance of parallel level at the two⁃stage transmission system was more easily affected by the error than the torsion level, so the output member should have a floating amount.To sum up, with the increase or decrease of the system error, it would have a bad effect on the static load⁃sharing performance of the system.The research results can provide scientific basis for the determination of manufacturing error and installation error accuracy of coaxial reducer transmission system and the de⁃termination of average load coefficient. © 2021, Editorial Department of Journal of Aerospace Power.
