Large playground equipment
①The front and rear axles are not parallel, and the coplanarity of the sprocket is poor. In terms of wear life, the performance of the chain depends to a large extent on whether the front and rear axles and the sprocket are installed correctly. The requirement is: the parallelism of the front and rear axles is within 1/300. The coplanarity of the front and rear wheels is between 0.5 and 1.0 mm/m. If the above-mentioned problems are found during the operation of the chain, it should be adjusted in time. (amusement park rides)
②The chain tension is abnormal. The tension of the chain is related to the drooping 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. If the center line is driven vertically or subjected to vibration load, the reverse drive should make the chain more tensioned. (amusement park rides)
③The chain and the sprocket do not fit well. If the chain and the sprocket do not fit well, it may be that the chain hinge is worn and the pitch is elongated. If there is a phenomenon of tooth skipping, replace the chain in time. If the sprocket is worn out, replace it to avoid damage to the new chain. (amusement park rides)
④The chain shakes. The possible reasons are that the chain is too loose, the load is too large, or one or more chain links are not flexible. The solution is to install a chain tensioner or an adjustable center distance. Reduce the load if possible. (

⑤ Excessive chain running noise may be caused by non-coplanar chain wheels, too large or too small chain tension, insufficient lubrication, chain and sprocket wear, or excessive chain pitch size. The solution is to check the coplanarity of the front and rear axles parallel to the sprocket and correct them. Adjust the center distance and tensioning device to obtain proper tightness and ensure lubrication to the workpiece. (amusement park rides)
⑥The chain plate is side-grinded. If the inner surface of the inner link plate is severely worn, it means that the transmission is not aligned. The solution is to check the alignment of the shaft and the sprocket. If there is no problem with the installation, you can observe whether the rigidity is insufficient due to excessive load and deformation during operation. (amusement park rides)
⑦The chain plate is fatigued. When the load is too large and exceeds the fatigue limit of the chain plate, the chain plate will undergo fatigue failure, causing tiny cracks around the hole until it breaks. The solution is to reduce the load or replace a chain with a large carrying capacity. (amusement park rides)
⑧ The pin is worn out. The reason may be due to insufficient lubrication. Always check whether there is abrasive in the lubricating oil or change the lubrication method. (amusement park rides)
⑨The pin is glued together. 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.

⑩The sprocket teeth are worn. If there is obvious wear on both sides of the sprocket teeth, the transmission alignment is not good. If there is a "curved groove", it means that the sprocket should be replaced with excessive wear. You can also install the sprocket backwards so that the lighter wear side faces the chain. It is best to replace the excessively worn sprockets together with the chain. (amusement park rides)
Many playground equipment also need regular maintenance and maintenance, so as to extend the service life of the machine!
