In recent years, there have been frequent problems of amusement rides caused by the failure of amusement equipment in the amusement market, which is distressing. Only from the root cause of the problem of amusement equipment failure can we provide tourists with a reliable amusement place. Common faults and troubleshooting methods of large playground equipment, let's take a look with Kangyuan Xiaobian!

① 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.

②The chain tension is abnormal. The tension of the chain is related to the sag 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.

③ The chain and 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.

④The chain shakes. 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.

⑤ The chain running noise is too loud, the reason may be that the sprockets are not coplanar, the chain is too tight or too small, the lubrication is insufficient, the chain and the sprocket are worn, or the chain pitch is too large. The solution is to check the parallelism of the front and rear axles and the coplanarity of the sprockets to correct them. Adjust the center distance and tensioning device to obtain proper tightness and ensure lubrication to the workpiece.

⑥ side grinding of chain plate. 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.

⑦Chain 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.

⑧ The pin shaft is worn. The reason for this may be due to insufficient lubrication. Always check the lubricating oil for abrasives or change the lubricating method.

⑨ The pin is glued. The pin shaft 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.

⑩ 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.

Many playground equipment also need regular maintenance and maintenance, so as to prolong the service life of the machine!
