Single girder bridge crane coupling maintenance

Nov 14, 2017
Single girder bridge crane coupling is an important transmission components on the crane, to ensure its normal safe work, it should be regularly checked and maintained, as follows:
 
1. Check the tooth profile coupling tooth;
 
2. Check the inner and outer ring center line swing oscillating quantity;
 
3. Check the coupling installation radial displacement error is within the allowable range or not;
 
4. If there is no radial displacement, check whether the two couplings are concentric or not;
 
5. If the couplings is not concentric, should check the outer lane skew angle;
 
6. The inner and outer ring end face swing: Diameter (40 ~ 100) mm, the allowable swing amount is ± 0.01; Diameter (100 ~ 200) mm, the allowable swing amount is ± 0.02; Diameter (200 ~ 400) mm, the allowable swing amount is ± 0.04 ,; Diameter (400 ~ 800) mm, the allowable swing amount is ± 0.08; Diameter (800 ~ 12000) mm, the allowed swing amount is ± 0.120.
