Bearing hole amend

Bearing hole amend while the extravagant wear of the bearing hole could be boring amend casement way. Inlayed material can[2] ht20-40 gray cast iron. Casement, firstly sets the machined diam sizing, pressed out into the bearing hole, and so sets inner diam boring classical sizing. Boring shaft hole cylindricity divergence ought be not larger than 0.03mm; upright divergence inward the basic coaxal two holes in axis machining superficial 100mm, distance ought be not larger than 0.05mm; a different axes The level of divergence of all hole parallel of latitude to the axis vertebra on the full distance ought be fewer than 0.06mm.

Broadcaster gear case 2 could be full complement plate of the gearbox case crack and crack amend case perforations and perforation amend welding amend or filling elastic. Amend of the filling plate, along the cracking or perforation round drill a amount of holes with a diam of 4.9mm, tapping M6 threaded find out open blocking around 3mm thickly iron plate, inward the matching location of the irons plate drill diam 6.5mm hole sandwiched between the iron plate and the side wall of the asbestos pad iron plate and shell m6 × 1.0 screws tightened up. Welding stop time, you must drill holes out of 3.5mm diam at both closings of the crack, open v-shaped groove on the crack, coldness welding electrode of copper and irons or casting irons electrode. Gum stop time, must too be finished hole, open v-shaped grooves, and so epoxy filling ac in gear motor
