Several forms of conveyor chain failure

Conveyor chain should be a common industrial chain. In the process of industrial production, especially in many food processing, the conveyor chain is used in the way of assembly line, which has a wide range of use and high frequency of use. Therefore, it often has wear failure. If combined with the improper use method, it will cause great damage to the chain.

Wear failure is a common and obvious manifestation. There are many reasons for this failure. The main reasons are poor chain material and improper operation of workers. Hongshuo chain introduced to you: the best way to solve this problem is to add idler in the middle and use the weight of idler to tighten the plate chain. The smallest part of the chain that is easy to wear is the sprocket and the pin shaft. The wear of these two parts is mainly due to the lack of local lubrication, so in order to avoid this phenomenon, the operator should pay attention to regularly check the lubrication effect, add lubricating oil in time, check whether there is abrasive in the lubricating oil or change the lubrication mode. When there is slight wear on the sprinket, it can be installed reversely, so that the less worn side faces the chain. In addition, if the use environment is bad or the lubrication seal is bad, it will cause the hinge to wear. Once the chain hinge is worn, the chain link becomes longer, and it is easy to cause tooth skipping or chain breaking when working, reduce the service life of the chain, and accelerate the chain failure.

It is a gradual process for the conveyor chain to grow due to wear, which consists of three stages: the first stage is the initial running in. At present, most of the factories in our country are workers resting and machines not resting. Therefore, the conveyor chain is often overused, that is to say, the chain bears excessive load in the operation process, resulting in uneven stress, which is easy to break or be squeezed. For this situation, our chain factory can only solve it by strengthening parts.

In addition, in the process of low-speed and heavy-duty transmission, overload breaking is also a common failure mode. Under a certain service life, the chain will accelerate the wear when the lubrication seal is poor or the working condition is bad, resulting in a large reduction of I limit power and overload pull off fault.
