ABSTRACT:
A puller driving structure is connected to a fixing module and a propping module for installing or removing a bearing, and the structure connects a hydraulic driving device with a connecting module, and the connecting module is connected to a plurality of slide rods and a plurality of resilient elements of a position resuming module, such that an actuating element is actuated on each slide rod, and the hydraulic driving device presses and moves the actuating element, and each resilient element presses and props the actuating element in an opposite direction to resume its original position, so as to achieve a better balance during the use of the puller driving structure provides a better concentricity for the bearing and the spindle.
