Common faults of gear coupling in work
Common faults in the work of gear couplings:
①The internal and external tooth surfaces of the coupling are severely worn.
②The axial displacement of the inner gear ring of the coupling is large, and it can't even mesh.
③The internal and external teeth of the coupling are broken.
④The coupling bolts are broken.
The main reasons for the above failures are as follows:
First, there is insufficient or lack of oil in the coupling of the lifting accessories.Or improper use of grease causes calcification of the grease, resulting in failure to lubricate between the tooth surfaces, or poor lubrication, resulting in serious tooth surface wear. In this case, replace the new grease and regularly inject qualified grease oil to prevent oil leakage. The amount of oil is sufficient. Can be avoided.
Second, the horizontality and coaxiality errors of the two shafts are too large, which exceeds the range that the coupling can compensate, which makes the shaft teeth and the internal teeth mesh 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. The internal and external teeth cannot be meshed until they cannot be transmitted.
