HYDRAULIC REMOVER Russian patent published in 1999 - IPC

FIELD: disassembly-assembly devices. SUBSTANCE: when resting on edge of catch surfaces ends of catches approach each other and enter part to be removed. Under effect of spring on levers of catches through sleeve bottom catches rest with their sides on internal surface of removed part. When rod-piston is moved out truncated cone rests on projections of catches, thereby locking the latter on part being removed. Then amplifier rests on rollers and rolls, on sleeve bottom, tie-rods come apart, and sleeve is separated from hydraulic cylinder. Sleeve skirt rests on body, surfaces of catches thrust on rear surface of part to be removed, and the latter is shifted relative to body. In this case, traction force exceeds direct force of rod-piston, thus providing for destruction of diffusion coupling of part to be removed with body. Then amplifier end face rests on sleeve bottom and completes dismantling of part by direct force of rod-piston. EFFECT: higher reliability of part dismantling. 4 cl, 1 dwg
