Repair of the flange frame after surfacing in the gas tank wagon
Regeneration consists in machining out the material at the point of contact with the nut in the plate on both sides of the hole for the actuator. Material losses are replaced with inserts. 4 pcs. new, turned inserts will be mounted in the grooves and screwed with screws. In future renovations, it is enough to replace the inserts.
Multi-bucket excavators working in open-pit mines are one of the largest mobile devices in the world. A characteristic element is a bucket wheel, often with a diameter exceeding 20 m. And it was the bearing seat of the bucket wheel that was the subject of our concern. It is clear that the time and cost of dismantling the bucket wheel would be gigantic, which is why the only solution became mobile machining. On the surface, this is a standard work, one obstacle in this case was a spigot with a diameter of Ø630, impossible to disassemble, and located in the center of the Ø1100 socket (an element with holes around the perimeter). The size of this journal also significantly limited the working space of the machine tool. Modification of the machine tool and the use of additional fasteners were required.
