How to repair single girder bridge crane coupling
time:Oct 19,2016
The single girder bridge crane coupling is an important transmission component on the crane to guarantee the work normally and safely. It should be regularly repaired. The steps are as follows:
1. Check the tooth surface of the toothed coupling;
2. Check the amount of swing of the inner and outer ring gear end with the center line;
3. Check if the radial displacement of the coupling installation is within the error tolerance;
4. If there is no radial displacement, check if the two couplings are concentric;
5. If the coupling are not concentric, the skew angle of outer ring line should be checked;
6. The inner and outer ring end swing amount: diameter (40~100)mm, allowable swing amount is ±0.01; diameter (100~200)mm, allowable swing amount is ±0.02; diameter (200~400)mm, allowable swing amount ±0.04,; diameter (400~800)mm, allowable swing amount is ±0.08; diameter is (800~12000)mm, allowable swing amount is ±0.120.
