1. Lifting accessories coupling oil shortage or lack. Or improper use of grease, resulting in calcification of grease, resulting in non-lubrication between the tooth surfaces of Plum Blossom Elastic Couplings, or bad lubrication, resulting in serious wear of the tooth surfaces. This situation can be avoided as long as new grease is replaced, qualified grease oil is injected regularly, oil leakage is prevented, and the amount of oil is sufficient.
2. The errors of the two axes'level and coaxiality are too large to be compensated by the coupling, which makes the engagement between the axle teeth and the inner teeth incorrect and causes local contact and additional moment. This additional moment can be decomposed into an axial force. Acting on the inner gear ring, the force depends on the deviation, which is proportional to the deviation. The larger the deviation, the greater the force, resulting in the axial displacement of the inner gear ring of the hoisting fitting coupling. If the displacement is too large, it will be uncontrollable, resulting in serious wear and tear of gears, even broken teeth, internal and external teeth can not mesh until they can not drive.
How to solve the failure of plum blossom coupling?
1. It is difficult to deal with the failure of Plum Blossom Elastic Couplings. It needs to stop production, i.e. re-aligning, or re-aligning the reducer, or re-aligning the drum. Firstly, locate the position where the deviation error is bigger, so we must first measure the deviation of the coupling to that side, that is, to measure the level of the spindle and the coaxiality of the coaxiality and the coaxiality of the reducer spindle, and to re-leveling and correcting according to the quality standard, we can eliminate the fault.
2. The horizontal and concentricity errors of the two axes are large, which are basically similar to the causes of gear wear of crane coupling.
3. The main reason is that the connecting bolt of Plum Blossom Elastic Coupling is subjected to additional bending moment besides normal force, which causes it to break. This kind of reason mostly occurs in the horizontal height difference around the reducer spindle. Furthermore, the smaller bolt diameter, insufficient strength or poor bolt material can also cause bolt breakage.
