Couplings are inseparable from any enterprise equipment. The operation of the coupling plays a very important role. However, if it is used frequently in the equipment, it will inevitably cause the machine to be strained. Therefore, we need to carry out maintenance from time to time to guarantee the parts. Normal operation.The tooth surface of the gear coupling is severely worn, and the internal gear ring produces a large amount of axial displacement, and even cannot mesh, and the phenomenon of tooth breakage occurs.The bolts on the coupling are broken. These are the failures of the coupling.The coaxiality error is 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.The magnitude of this force depends on the magnitude 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 realign, or realign the side of the reducer, or realign the side of the reel.For the part with large offset error, first measure the offset of the coupling to that side, that is, measure the levelness and coaxiality of the main shaft and the level and coaxiality of the reducer main shaft, and re-level it according to the quality standard. Correction can eliminate the fault.At that time, it was measured that the concentricity deviation of the coupling was 2n, and the reducer side was low, which caused the lifting accessory coupling to fail to work, and the axial displacement of the inner gear ring exceeded the tooth width. After surveying and mapping, the reducer should be re-according to the quality standard. After alignment and adjustment, the operation is normal and the fault is eliminated.
