The invention discloses a mechanism for preventing axial endplay of a high-speed motor rotor in transportation and a mounting method of the mechanism and solves a problem of how to prevent axial endplay of a motor shaft in transportation of a high-speed motor. A first left step shaft annular hoop (15) and a second left step shaft annular hoop (18) which are adjustable in distance in the horizontaldirection are arranged in a gap between a left bearing seat (3) on the left side of a motor and a motor stator base (2), and the two hoops move back to back in the horizontal direction by rotating anabutting bolt (20), so the right side vertical face of the first left step shaft annular hoop (15) is made; the second right step shaft annular hoop (24) leans against a right side annular step surface (7) on a first left step shaft (11), so that the right side vertical surface of the second right step shaft annular hoop (24) leans against a right bearing seat left side vertical surface (10) of aright bearing seat (4); th
