Design and fabrication of portable port type intragrated hydraulic bearing press

  1. 1. DESIGN AND FABRICATION OF PORTABLE PORT TYPE INTRAGRATED HYDRAULIC BEARING PRESS (CAPACITY 7TON) ABSTRACT:  Portable Port type hydraulic power press is used to remove bearing from shaft in machine assembly area or use to insert any kind of bush in force fit manner. So there is no need t go machine shop to remove bearing from the assembly point. And it is portable one; we can take this any where the machine assembling point may be CONSTRUCTION WORKING OF HYDRAULIC CIRCUIT Hydraulic cylinders (also called linear hydraulic motors) are mechanical actuators that are used to give a linear force through a linear stroke. A. Hydraulic cylinders are able to give pushing and pulling forces of millions of metric tons, with only a simple hydraulic system. Very simple hydraulic cylinders are used in presses; here the cylinder consists out of a volume in a piece of iron with a plunger pushed in it and sealed with a cover. By pumping hydraulic fluid in the volume, the plunger is pushed out with a force of plunger-area * pressure. Here hydraulic circuit is a port type integrated one. No hoses are found .oil will passes through port only and no separate sump for oil storage .oil store around the shell of hydraulic cylinder itself ECWAY TECHNOLOGIES IEEE PROJECTS & SOFTWARE DEVELOPMENTS OUR OFFICES @ CHENNAI / TRICHY / KARUR / ERODE / MADURAI / SALEM / COIMBATORE BANGALORE / HYDRABAD CELL: 9894917187 | 875487 1111/2222/3333 | 8754872111 / 3111 / 4111 / 5111 / 6111 Visit: www.ecwayprojects.com Mail to: ecwaytechnologies@gmail.com
  2. 2. CALCULATION OF HYDRAULIC CIRCUIT The pushing or pulling force of a hydraulic cylinder is: F = Ab * pb - Ah * ph F = Pushing Force in N Ab = (π/4) * (Bottom-diameter)^2 [in m2] Ah = (π/4) * ((Bottom-diameter)^2-(Piston-rod-diameter)^2)) [in m2] pb = pressure at bottom side in [N/m2] ph = pressure at cylinder head side in [N/m2 ADVANTAGES  It is portable one  No hoses and electric equipment  Less space only required for mounting WORKING OPERATION: This machine has a hydraulic cylinder and piston assembly. Which works in a port type integrated hydraulic circuit. I this circuit there is no need for separate oil pump hydraulic houses, D.C valves, Pumps etc. These all those things are integrated with the hydraulic cylinder itself
