Abstract
PURPOSE: To improve a loading capacity and to enable pulling-off of a piston without removing a piston bar packing, by locating a screw part at its end, an axis hole having a staged part at an opening side, a coupling bar, a hydraulic piston, a perforation in a cross head pin, and a cross pulg.
CONSTITUTION: High pressured oil fed to an oil passage 9 rises an internal pressure in an oil chamber 8, and a coupling bar 3 lengthens as a result of the bar 3 being pressed downward with an oil piston 6. A nut 4 is screwed into a bottom end of the coupling bar 3, and the coupling bar 3 being lengthened is inserted into a cross head pin 2. A piston bar 1 is laid on an abutting surface of the cross head pin 2, and a cross plug 5 is inserted into a perforation 11. As a result of the oil pressure in an oil chamber 8 being released, the coupling bar 3 is going to contract, but refrain from contracting due to the cross plug 5 inserted between the nut 4 and the piston bar 1. And thus, the piston bar 1 is firmly tightened to the cross head pin 2 through the work of the nut 4 and the cross plug 5 due to the elastic force.
