    Abstract
  • The lumped mass method was adopted to establish the dual-path helical gear transmission system dynamic model and dynamic equation; and considering the gear meshing deviation and time-varying meshing stiffness, change rule of the dynamic load coefficient and the load sharing coefficient of transmission system were studied in the case of different support stiffness and separated torque angles. The results show that: (1) the larger support stiffness is conducive to the transmission system load sharing characteristic and stability, and the load sharing characteristic is close to the ideal at the case of 16 times the initial support stiffness; (2) the dual-path helical gear transmission system's separated torque angle has a great influence on the dynamic load coefficient and the load sharing coefficient, and the system loading sharing characteristic gets the most optimal at the separated torque angle of 110 degree; (3) even 1μm meshing deviation has a great negative effect on the system loading sharing characteristic, so it should be strictly controlled.
