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.
Claims23
A puller driving structure, connected to a fixing module and a propping module, for installing or removing a bearing, and the puller driving structure comprising:
- a hydraulic driving device, having a body, a driving handle and a driving rod passed through the center of the body, and the body having an adjusting portion disposed at the exterior of the driving rod, and the driving handle being provided for the driving rod to extend or retract the adjusting portion of the body;
- a connecting module, sheathed onto the adjusting portion of the body, and having a plurality of fixing holes;
- an actuating element, installed at the bottom of the connecting module, and having a plurality of through holes corresponding to each fixing hole of the connecting module, and the center of the actuating element corresponding to the driving rod provided for the driving rod to press and actuate the actuating element, and the actuating element having a plurality of support arms extended from the center towards the outside, and each support arm having a guide rail portion for installing the propping module;
- a position resuming module, installed at the bottom of the actuating element, and having a plurality of slide rods, a plurality of resilient elements and a fixing plate, and each slide rod passing through each fixing hole of the connecting module and having each resilient element passing towards the fixing plate, and the fixing plate having a plurality of fixing holes corresponding to each slide rod for installing each slide rod, and after each slide rod is extended and passed into each fixing hole, each slide rod is fixed onto the fixing plate by a fixing element, and a fixing portion being protruded from the center of the bottom of the fixing plate for installing the fixing module.
