The main reason for the failure of the drum gear coupling

XINLAN coupling analysis of lifting parts drum type gear typeCouplingInsufficient or lack of oil.Or improper use of grease causes calcification of the grease, resulting in the inability to lubricate between the tooth surfaces, or poor lubrication, resulting in serious tooth surface wear. In this case, just replace the new grease and inject qualified grease regularly to prevent oil leakage. The amount of oil is sufficient. Can be avoided.The horizontality and coaxiality errors of the two shafts are too large, exceeding the range that the coupling can compensate, making the shaft tooth and the internal tooth meshing incorrectly, causing local contact and additional torque.And this additional moment can be decomposed into axial force.Acting on the inner gear ring, the magnitude of this force depends on the size of the deviation, and is proportional to the deviation. The greater the deviation, the greater the force, resulting in axial displacement of the inner gear ring of the coupling of the lifting accessories.If the displacement is too large, it will be uncontrollable, resulting in serious gear wear and even broken teeth.It is difficult to deal with this kind of fault, and it needs to stop production.That is to re-align, or re-align the side of the reducer, or re-align the side of the reel.First find out the part with large offset error, so first measure the side of the coupling that is offset, that is, measure the level and coaxiality of the main shaft and the level and coaxiality of the reducer main shaft, and then press the quality again. Standard leveling and leveling can eliminate the fault.
