How to repair the severely damaged blow molding machine gear?
â‘ If the involute tooth surface of a pair of straight-toothed cylindrical gears has pits, it can be smoothed and smoothed with whetstone before use; the pair of gears can also be removed from the shaft, turned over 1800, and then installed on the drive shaft So that the involute tooth surface of the other surface without wear is engaged.
â‘¡If the gear teeth with a small modulus specification are broken, generally new gears are replaced. If the gear teeth with larger modulus specifications are broken and there are no spare parts, the method of supplementing gears can be used.
Before repairing the gears of the bottle-blowing machine, the fitter should make the tooth shape model and the adjacent tooth pitch model. Tooth shape welding: first cut out the trapezoidal groove at the broken tooth, shape a tooth according to the tooth shape, then insert it into the trapezoidal groove for welding, and then file the tooth shape according to the tooth shape and the adjacent tooth pitch model. Repair method: first drill and tap at the broken tooth, then screw in a row of screws according to the tooth width, and then correct and file the tooth shape according to the two patterns of tooth shape and pitch.
