A BALL BEARING WITHDRAW DEVICE

摘要

PURPOSE: A ball bearing ejection device is provided to prevent the falling of a bearing structure by stably supporting operating rods with a compression block. CONSTITUTION: A ball bearing ejection device comprises a hydraulic ram, a reaction force plate(20), a plurality of operating rods(30), and insertion balls(40). The hydraulic ram is settled on the top of a supporting shaft. The reaction force plate is settled on the top of the hydraulic ram and lifted by a hydraulic operation. The upper ends of the actuating rods are supported by fastening nuts(31) coupled to the reaction force plate. The insertion balls are respectively coupled to the bottoms of the operating rods. Flat surfaces are formed on both sides of an insertion ball so that the outer diameter of the insertion ball is reduced and the insertion ball is inserted between the outer and inner races of a ball bearing.
