With the construction and development of modern social economy and the continuous improvement of people's living standards, entertainment activities have played a huge role in enriching people's lives, especially some large playgrounds have gradually become a good place for young people to pursue stimulation and relieve stress.
What is a must for every playground? There is no doubt that it is large-scale amusement equipment. Each playground is equipped with a variety of large-scale amusement equipment, so as to attract tourists. Affected by various factors, amusement facilities often have various failures and accidents during operation, resulting in casualties and property losses. So how to solve the problem of large amusement equipment? The manufacture of large-scale amusement equipment will tell you.
1. Chain jitter. The possible cause is that the chain is too loose, the load is too high, or one or more links are inflexible. The solution is to install a chain tensioner or adjustable center distance. Reduce load if possible.
Second, the chain plate fatigue. When the load is too large and exceeds the fatigue limit of the chain plate, the chain plate will suffer fatigue failure, and tiny cracks will be generated around the hole until it breaks. The solution is to reduce the load or replace the chain with a higher load capacity.
3. The sprocket teeth are worn. If there is significant wear on both sides of the sprocket teeth, the drive alignment is poor. If a 'bend groove' occurs, it means that the sprocket should be replaced, or the sprocket can be reversely installed so that the less worn side faces the chain. Excessively worn sprockets are best replaced with the chain.
Fourth, the pin shaft wear. China Amusement Equipment Information Network learned that the cause of pin wear may be due to insufficient lubrication. Always check the lubricating oil for abrasives or change the lubricating method.
Fifth, the chain and the sprocket do not cooperate well. If the chain does not cooperate well with the sprocket, it may be that the hinge of the chain is worn and the pitch is elongated. If there is a tooth skipping phenomenon, the chain should be replaced in time. Also replace the sprocket if worn to avoid damaging the new chain.
Sixth, the chain plate side grinding. If the inner surface of the inner chain link is severely worn, it means that the transmission is not aligned. The solution is to check the alignment of the shaft and sprocket. If there is no problem with the installation, it can be observed whether the rigidity is insufficient due to excessive load deformation during operation.
Seven, pin gluing. China Amusement Equipment Information Network reminds you that pin gluing is generally caused by insufficient oil supply. If only one end is glued, check the installation of the shaft and the sprocket, whether the shaft is parallel, whether the sprocket is coplanar, and whether the shaft and the sprocket move during operation.
8. The chain tension is abnormal. China Amusement Equipment Information Network learned that the tension of the chain is related to the sagging distance of the loose edge of the chain. For horizontal and inclined transmission with adjustable center distance, the sag of the loose edge of the chain should be about 2% of the center distance. The centerline is vertically driven or subjected to vibration loads, and the reverse drive should make the chain more tensioned.
Nine, the chain running noise is too large. This can be caused by sprockets that are not coplanar, too much or too little chain slack, insufficient lubrication, worn chain and sprockets, or an oversized chain pitch. China Amusement Equipment Information Network reminds you that when you encounter this problem, you should check the parallelism of the front and rear axles and the coplanarity of the sprocket to correct it. Adjust the center distance and tensioning device to obtain proper tightness and ensure lubrication to the workpiece.
10. The front and rear axles are not parallel, and the coplanarity of the sprockets is poor. In terms of wear life, the performance of the chain depends to a large extent on the correct installation of the front and rear axles and sprockets. The requirements are: the parallelism of the front and rear axles is within 1/300. The coplanarity of the front and rear wheels is 0.5 to 1.0 mm/m. If the chain finds the above problems during operation, it should be adjusted in time.
