Large-scale amusement equipment mechanical operation failure and solution

Large-scale amusement equipment mechanical operation failure and solution

Affected by various factors, various obstacles often occur during the operation of the amusement facilities and cause accidents, resulting in casualties and property losses. Therefore, by analyzing some fault phenomena that often occur in amusement facilities, and adopting correct treatment methods and developing comprehensive preventive measures, it is possible to more effectively avoid various types of accidents. The following is a list of common mechanical failures and solutions for large-scale amusement equipment in operation for reference.

First, the chain shakes. The possible reason is that the chain is too loose, the load is too large, or one or more links are not flexible. The solution is to install a chain tensioner or an adjustable center distance. Reduce the load if possible.

Second, the chain plate fatigue. When the load is too large to exceed the fatigue limit of the link plate, the chain plate undergoes fatigue damage, and micro cracks are generated around the hole until it breaks. The solution is to reduce the load or replace the chain with a large carrying capacity.

Third, the sprocket teeth wear. If the sprocket teeth have significant wear on both sides, the drive alignment is not good. If the "curved groove" is generated, the sprocket should be replaced by excessive wear. The sprocket can also be reversed so that the lighter one faces the chain. The excessively worn sprocket is preferably replaced with the chain.

Fourth, the pin wear. China Amusement Equipment Information Network learned that the cause of pin wear may be due to insufficient lubrication. Always check the lubricant for abrasive or change the lubrication.

5. The chain and the sprocket do not cooperate well. If the chain does not work well with the sprocket, the chain hinge may be worn and the pitch is elongated. If there is a tooth skipping phenomenon, the chain should be replaced in time. If the sprocket wears out, replace it to avoid damaging the new chain.

Sixth, the side of the chain plate grinding. If the inner surface of the inner chain link is worn out, the drive is not aligned. The solution is to check the alignment of the shaft and sprocket. If there is no problem with the installation, it is possible to check whether there is insufficient rigidity due to excessive load deformation during operation.

Seven, the pin is glued. China Amusement Equipment Information Network reminds you that pinning glue is generally caused by insufficient oil supply. If only one end is glued, check the shaft and sprocket installation, whether the shafts are parallel, whether the sprocket is coplanar, and whether the shaft and sprocket are moving during operation.

Eight, the chain tension is not normal. China Amusement Equipment Information Network learned that the tension of the chain is related to the distance between the loose edges of the chain. For horizontal and inclined transmissions with adjustable center-to-center distance, the sag of the chain's loose side should be about 2% of the center-to-center distance. The centerline is vertically driven or subjected to shock loads, and the reverse drive should make the chain more tensioned.

Nine, the chain running noise is too large. The reason may be that the sprocket is 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. China Amusement Equipment Information Network reminds you that when encountering such problems, it is necessary to check the front and rear axis parallel and the sprocket coplanarity to correct. Adjust the center distance and tensioning device to achieve proper tightness and ensure lubrication to the workpiece.

Ten, the front and rear axles are not parallel, and the sprocket's coplanarity is poor. For wear life, the performance of the chain depends to a large extent on the correct installation of the front and rear axles and sprocket. The requirement is that 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.
