What are the common mechanical failures

Manufacturing of large-scale amusement equipment

The manufacturing of large-scale amusement equipment is a favorite among many people, and now more and more large-scale amusement parks are emerging. During the manufacturing process of these large amusement equipment, some malfunctions may occur. In order to ensure the safety of amusement personnel, it is necessary to adopt some correct handling methods for these malfunctions, so as to better and effectively avoid various accidents.

Chain shaking

Possible reasons may be that the chain is too loose, the load is too high, or one or more chain links are not flexible. The solution is to install a chain tensioner or an adjustable center distance. If possible, reduce the load.

Chain plate fatigue

When the load exceeds the fatigue limit of the chain plate, the chain plate undergoes fatigue failure, producing small cracks around the hole until it fractures. The solution is to reduce the load or replace the chain with a higher load-bearing capacity.

Wear of sprocket teeth

If there is obvious wear on both sides of the sprocket teeth, it is due to poor alignment of the transmission. If there is a "bend groove", it indicates excessive wear and the sprocket should be replaced. Alternatively, the sprocket can be reversed so that the less worn side faces the chain. It is best to replace the excessively worn sprocket together with the chain.

Wear and tear of the pin shaft

The service life of the pin shaft is very long, and if there is wear on the pin shaft. The usual reason is due to insufficient lubrication. Regularly check whether there are abrasives in the lubricating oil or change the lubrication mode.

The chain and sprocket do not match well

If the chain does not fit well with the sprocket, it may be due to wear of the chain hinge and elongation of the pitch. If there is tooth jumping, the chain should be replaced in a timely manner. If the sprocket is worn, it should also be replaced to avoid damaging the new chain.

Chain plate side grinding

If the inner surface of the chain link is severely worn, it indicates that the transmission is not aligned. The solution is to check the alignment of the shaft and sprocket. If there is no problem with installation, observe whether the insufficient rigidity is caused by deformation due to excessive load during operation.

Pin axis bonding

Pin shaft bonding is generally caused by insufficient oil supply. If only one end is glued, it is necessary to check the installation of the shaft and sprocket, whether the shaft is parallel, whether the sprocket is coplanar, and whether the shaft and sprocket move during operation.
