轮对大齿轮退卸机

本发明公开了一种轮对大齿轮退卸机，轮对大齿轮退卸机包括：机架；轮轴驱动件，轮轴驱动件为两个且分别固定在机架左右两侧的相对位置；退卸装置，退卸装置安装在机架上且位于两个轮轴驱动件之间，退卸装置包括：退卸套和退卸插片，退卸套的内径大于轮对的轴承外径且外径小于大齿轮的直径，退卸插片在第一位置和第二位置之间可移动，退卸插片在第一位置时，退卸插片适于插套在轮对的轮轴上且用于抵靠大齿轮一侧的轴承，退卸插片在第二位置时，退卸插片远离轮轴。通过设置退卸套和退卸插片，可以分步骤地完成对轮对上的大齿轮和大齿轮两侧轴承的退卸，从而可以提高轮对大齿轮的退卸效率。 The invention discloses a wheel set large gear dismounting machine which comprises a machine frame, two axle driving parts fixed to opposite positions of the left and right sides of the machine frame correspondingly, and a dismounting device mounted on the machine frame and located between the two axle driving parts. The dismounting device comprises a dismounting sleeve and a dismounting insert piece, the inner diameter of the dismounting sleeve is larger than the outer diameter of a bearing of a wheel set, and the outer diameter of the dismounting sleeve is smaller than the diameter of a large gear. The dismounting insert piece can move between a first position and a second position. When located at the first position, the dismounting inser
