A gearbox combination sealing structure is introduced,which adopts a combination of non-contact oil ring centrifugal seal,contact oil seal and axial labyrinth seal.This sealing method achieves axial sealing in a compact structure,which greatly reduces the potential risk of oil leakage at the input and output ends of the gearbox.This sealing method is especially suitable for outdoor equipment,dusty environment,and other places where it is not easy to maintain frequently.
