Ring Chain Classification

First, the classification of the ring chain
The grade of the ring chain is used to indicate its quality and strength and other indicators. At present, the national standard GB/T 12718-2006 stipulates three levels: light load level, medium load level and heavy load level.

 

Second, the performance parameters of each level
1. Light load class:

The maximum working load of light load class is 4kN, the transmission efficiency is high, the friction loss is small, and it is suitable for the occasions of low power, low speed and heavy precision transmission.

2. Medium load grade:

The maximum working load of the medium load class is 10kN, which is suitable for the medium load transmission system, and the transmission efficiency is not lower than the light load class.

3. Heavy duty level:

The maximum working load of the heavy-duty class is 20kN, and the transmission efficiency is relatively low, but the carrying capacity is strong, and it is suitable for the heavy-duty transmission system with high power, high speed and large load.

In addition to the above maximum working load, the grade of the ring chain is also related to its contact area, tooth shape and other parameters, which need to be selected according to the actual situation in specific applications.

 

Third, the selection of ring chain
The correct selection of the ring chain can improve the transmission efficiency, but also extend the service life of the ring chain. When selecting, it is necessary to determine the maximum working load and select the appropriate grade according to the actual transmission needs.

 

At the same time, it is also necessary to carry out regular maintenance and maintenance during use, including timely replacement of the chain with serious wear, cleaning and maintenance of the chain surface and other operations to ensure its normal operation and extend its service life.
