First, the commutation method: For single-face wear of the gear surface, if the structure allows, the gear can be swapped or flipped 180 degrees, use its unworn side, but it is best to use in pairs, or to change the gear Made into new products to ensure normal gear engagement.
Second, insert gear ring method: tower gear is made of several gear together, the damage of each gear is different. If the teeth of individual gears are worn out, they can be repaired by replacing the ring gear. First go to the gears that need to repair the gears, and make a ring gear press-fitted on the parts of the car's gear teeth. In order to prevent the new ring gear from loosening, it can be spot-welded circumferentially at the joint of the ring gear and the gear, or drilled into a stud to fix it.
Third, insert the tooth method: the load is not high, the speed is not high gear, after the individual teeth are destroyed, repair the bad gear root planing trapezoidal groove on the planer, with a certain degree of tension to the same with the groove of the new The tooth germ presses in, welding and machining plastic.
Fourth, surfacing welding method: gear teeth or individual wear or wear on both sides of the limit exceeds the limit, etc., can be based on gear damage, the entire or part of the surface of the gear overlay welding one or more layers of metal. The welding repair of gears can be divided into welding and gas welding. Surfacing repair gear, simple operation, good repair quality.
5. Screw-toothing method: Remove the toothed and worn gear, clean it, measure the thickness of the tooth root with a vernier caliper, and level and clean the tooth-reduced area with a knife. According to the thickness of the tooth root, choose the screw of the corresponding diameter, the length of the thread is not shorter than 1.5-2 cm. Then use a bench drill on the tooth drop area of ​​the gear to drill a hole of the same diameter as the screw and tap it with a tap. Tighten the screw in the screw hole, then use a hacksaw to saw out the screw that is higher than the top part of the teeth, and then use the crusher to process the tooth with the same tooth shape, and then use it.
