Abstract
The invention discloses a stepped hollow shaft which comprises a first shaft section, a second shaft section and a third shaft section. The first shaft section, the second shaft section and the third shaft section are coaxial. The second shaft section is located in the middle of the first shaft section, and the third shaft section is located at one end of the first shaft section. A through hole is formed in the first shaft section, a through hole is formed in the second shaft section, and a through hole is formed in the third shaft section. The through holes in the first shaft section, the second shaft section and the third shaft section are coaxial and identical in diameter. The stepped hollow shaft is provided with a segmented shaft body and is hollow so that the stepped hollow shaft can meet the using and mounting requirements for segmented connection or segmented transmission.
