There are two ways to repair the broken teeth of the big gear ring of ball mill: 1. Method 1: Turn the broken teeth upward, level the fracture with a flat shovel, and then drill holes with a bit with a diameter slightly smaller than the width of the dressing surface, with a hole spacing of 0.9- 1.2 times the hole diameter. When the tooth profile damage is small, the hole spacing can be appropriately increased. At the same time, select a tap with a depth of 1.5-2.0 times the aperture for tapping. Screw a bolt with the same hole depth and tooth height and length into each hole, and make the tooth shape by surfacing after fastening. Finally, the new welding tooth profile is basically the same as the original tooth profile of the hand mill. This is an emergency treatment method. Pay attention to empty materials and polished bodies before repair, and avoid using hammers, flat shovels and gas welding during shaping. In order to ensure the repair quality, the cast steel gear ring is welded by cold welding, and the cast iron gear ring is welded by hot welding. If conditions permit, the tooth profile of the side contacting the pinion can be prepared in advance and welded on the bolt. 2. Method 2: Use oxygen-acetylene flame to heat the periphery of the surfacing part to about 300℃, then carry out surfacing, and check with the tooth template. After surfacing, it can be machined by machine tool, or the tooth profile can be trimmed by hand grinding wheel, shovel and file, and the tooth profile and pitch can be checked by tooth profile template to make the tooth profile basically consistent with the original tooth profile. Finally, local surface heat treatment is carried out by oxygen-acetylene flame or other heating methods.
