Impeller and bearing dismounting device

The utility model relates to the field of chemical machinery, and discloses an impeller and bearing dismounting device which comprises a support (3), a plurality of claws (1) circumferentially arranged on the support (3) and a driving part (8), the claws (1) can be hooked on the edge of an impeller or a bearing, and the driving part (8) can apply acting force away from the direction of the impeller or the bearing to the support (3). Therefore, the impeller or the bearing moves relative to the shaft (7). By means of the technical content, the multiple claws on the support can be hooked to the edge of the impeller or the bearing by moving the support, then the support is pulled under the action of the driving part, the impeller or the bearing is hooked out of a shaft through the claws, damage of the dismounting device to the impeller and the bearing can be small through the multiple stress points, and the dismounting efficiency is improved. And the detached impeller or bearing can be repeatedly used. 本实用新型涉及化工机
