變速箱齒輪常見的缺陷有：齒側和齒端面磨損、齒面剝落、輪齒折斷、齒圈松動或破裂等。
濟南自動變速箱修理時可根據具體情況采用下列不同的修復方法：
Common defects of gearbox gears include wear of gear side and end face, peeling of gear surface, broken gear teeth, loose or broken gear ring, etc. Jinan automatic transmission can be repaired by the following different methods according to the specific situation:
（1）換向法。左右對稱的齒輪在出現單面磨損后，可將其左右齒輪調換位置或翻轉180°繼續使用。
(1) Reversing method. After unilateral wear occurs to the left and right symmetrical gears, the left and right gears can be replaced or turned 180 ° to continue using.
（2）鑲齒法。變速箱齒輪中如果負荷小、轉速不高的齒輪出現了斷齒，可將斷齒的齒根部位刨出或銑出燕尾槽，并以一定的過盈量壓入新齒坯，經焊牢后整形可繼續使用。
(2) Tooth inlay method. If the gear with small load and low speed in the gearbox has broken teeth, the tooth root of the broken teeth can be planed or milled out of dovetail groove, and a certain amount of interference is pressed into the new gear blank, which can be used again after welding and shaping.
（3）鑲齒圈法。若變速箱上的塔形齒輪某部位出現輪齒磨損超限，可先將其退火，車去該部的全部輪齒，另制一個齒圈壓裝在車去的輪齒處，為防齒圈松動，可用電焊在接合處點焊，或沿圓周鉆孔用穩釘固定。
(3) Ring gear insert method. If the tooth wear of a certain part of the tower gear on the gearbox exceeds the limit, it can be annealed first, and all the teeth of that part can be turned off, and another gear ring can be made and pressed on the gear teeth to be turned off. To prevent the gear ring from loosening, spot welding can be used at the joint, or drilling along the circumference can be used to fix it with stable nails.
（4）堆焊法。若變速箱齒輪的個別輪齒折斷或齒面、齒端磨損超限，可先用汽油將齒輪表面的污物、銹漬除盡，使其露出金屬光澤，再進行堆焊，然后經機械加工整形再經回火處理后可繼續使用。
(4) Surfacing method. If the individual teeth of the gearbox gear are broken or the wear of the tooth surface and tooth end exceeds the limit, the dirt and rust stains on the gear surface can be removed with gasoline first to expose the metal luster, then the surfacing welding can be carried out, and then the gear can be used after mechanical processing and shaping, and then tempering treatment.
