In recent years, the domestic large-scale amusement industry has experienced rapid development, with many cities constructing large amusement parks and an increasing number of large amusement facilities being put into operation. Due to various factors, amusement facilities often encounter various malfunctions and cause accidents during operation, resulting in casualties and property losses. Therefore, Shandong Huanwei reminds you that by analyzing some common malfunction phenomena of amusement facilities, adopting correct handling methods, and formulating sound preventive measures, you can more effectively avoid the occurrence of various accidents. Below, Shandong Huanwei provides a summary of common mechanical malfunctions and solutions for large amusement equipment during operation for your reference.

1. Chain shaking. Possible causes include excessively loose chain, excessive load, or one or more inflexible chain links. The solution is to install a chain tensioner or adjustable center distance device. If possible, reduce the load.

2, chain plate fatigue. When the load exceeds the fatigue limit of the chain plate, it will undergo fatigue failure, resulting in microcracks around the holes until it fractures. The solution is to reduce the load or replace the chain with one with greater load-bearing capacity.

3. Sprocket tooth wear. If there is noticeable wear on both sides of the sprocket tooth, it indicates poor transmission alignment. If "bending grooves" appear, it signifies excessive wear and the sprocket should be replaced. Alternatively, the sprocket can be installed upside down so that the less worn side faces the chain. It is best to replace the excessively worn sprocket along with the chain.

4. Wear of pin rollers. According to China Amusement Equipment Information Network, the wear of pin rollers may be caused by insufficient lubrication. It is necessary to regularly check whether there are abrasives in the lubricating oil or change the lubrication method.

5. Poor fit between the chain and sprocket. If the fit between the chain and sprocket is poor, it may be due to wear on the chain hinge or elongation of the pitch. If there is a tooth skip, the chain should be replaced promptly. If the sprocket is worn, it should also be replaced to prevent damage to the new chain.

6. Side wear of chain plate. If the inner surface of the inner chain link plate is severely worn, it indicates that the transmission is not aligned properly. The solution is to check the alignment of the shaft and sprocket. If the installation is correct, observe whether the rigidity is insufficient due to deformation caused by excessive load during operation.

7. 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, 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.

8. The chain tension is abnormal. China Amusement Equipment Information Network has learned that the tension of the chain is related to the distance of the chain's slack side from the vertical. For horizontal and inclined transmissions with adjustable center distances, the sag of the chain's slack side should be around 2% of the center distance. For vertical centerline transmissions or under shock loads, the reverse transmission should make the chain more tensioned.

9. The chain operates with excessive noise. The possible reasons could be that the sprocket is not coplanar, the chain tension is too high or too low, the lubrication is insufficient, the chain and sprocket are worn, or the chain pitch size is too large. China Amusement Equipment Information Network reminds you that when encountering such problems, it is necessary to check the parallelism of the front and rear axles and the coplanarity with the sprocket, and make corrections accordingly. Adjust the center distance and tensioning device to achieve the appropriate tension and ensure lubrication reaches the workpiece.

10, the 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 largely on whether the installation of the front and rear axles and sprocket is correct. The requirements are: the parallelism of the front and rear axles should be within 1/300. The coplanarity of the front and rear wheels should be within 0.5~1.0 mm/m. If the above problems are found in the operation of the chain, they should be adjusted in time.
