A floating type sealing mechanism of an output shaft of a reduction gearbox comprises the output shaft, one end of the output shaft is located in a connecting base, the connecting base is located between the reduction gearbox and an end cover, an annular isolation plate is arranged in a groove of the connecting base used for assembling the isolation plate and matched with the output shaft in an empty sleeve mode, and the isolation plate is connected with the output shaft. The axial thickness of the isolation plate is smaller than the axial groove depth of the groove, the outer circumference of the isolation plate is in transition fit with the groove wall of the groove, a gap where the isolation plate is in transition fit with the connecting base is sealed through an O-shaped sealing ring, and an oil seal installation groove is formed in a circle center hole where the isolation plate is in clearance fit with the output shaft. And a framework type oil seal is positioned in the oil seal mounting groove to seal a
