How to know the specification model of chain

1, Measure the pitch of the chain, the distance between two pins .

2, Inner section width, this part is related to the thickness of sprocket .

3, The thickness of the chain plate, in order to know whether it is reinforced .

4, Roller outer diameter, some conveyor chains use large rollers.

5. Generally speaking, the above four data can be analyzed to find out the type of chain. There are two kinds of chains, A series and B series, with different outer diameter of rollers for the same pitch.

Structure

1. Among the similar products, the basic structure of the chain, i.e., according to the shape of the element, the parts and parts that engage with the chain, and the proportion of the size of the parts, is divided into the chain product series to which they belong. There are many kinds of chains, but their basic structures are only the following ones, and the others are the deformation of these kinds.

2. As we can see from the above chain structure, most of the chains are composed of chain plates, chain pins, bushings and other parts. Other types of chains are just the chain plate according to different needs to make different changes, some on the chain plate on the scraper, some on the chain plate on the guide bearing, there are also on the chain plate on the roller and so on, these are in order to be applied in different applications for the modification.

Inspection method

The accuracy of chain length should be measured according to the following requirements:

1.The chain is cleaned before measurement.

2. The measured chain is put around the two sprockets, and the upper and lower sides of the measured chain should be supported.

3. Before measurement, the chain should be kept in the state of one-third of the minimum ultimate tensile load for 1min.

4. When measurement is made, the specified measuring load is applied to the chain, so that the upper and lower sides of the chain will be tensioned, and the chain should be ensured to be properly fitted to the sprocket wheels.

5.Measure the center distance between two sprockets.

Measurement of chain elongation:

1. In order to remove the clearance of the whole chain, it is necessary to measure the chain under a certain degree of pulling tension.

2.Measurement is done at 6-10 knots in order to minimize the error.

3.Measure the inner L1 and outer L2 dimensions between the rollers of the number of links to find out the judgmental dimension L=(L1+L2)/2.

4.Find out the elongation length of the chain, and this value is compared with the value of the limit of use of the chain elongation in the previous item.

Chain structure: it consists of inner and outer links. It also consists of inner chain plate, outer chain plate, pin, sleeve, roller five small parts, the chain's quality depends on the pin and sleeve.
