There are many types of chains, including plate chains and double-speed chains. The fatigue failure of the plate chain is a problem we need to understand, but for the two-speed chain, the correct use is more important. The knowledge is helpful to prolong the service life of the chain.
As mechanical equipment often needs to operate 24 hours a day, the plate chain, as an important part of the chain, needs to have high requirements, because if it reaches a certain fatigue value, the chain will soon fail and fail.
If the plate chain in the process of operation load is too large, resulting in uneven force, it is easy to break or be squeezed. However, since the tension on the elastic side of the chain is different from that on the elastic side, the working state of the chain is an alternating tensile stress. After a certain number of stress cycles, the chain will be damaged due to insufficient fatigue strength.
In the case of plate chain failure, the problem of surface carburization can only be solved by means of strengthening to resist stress concentration. The waist of the chain plate is widened to reduce the stress concentration of the hole. The parts are shot peening and so on.
Two-speed chains are usually used only for two-speed chain conveyors. Through its acceleration function, the tooling board supporting the cargo can run quickly and reach the designated position. In the normal use of the equipment, due to normal or accidental wear and tear, the double-speed chain may appear a variety of abnormal phenomena, at this time must immediately stop using, timely repair, so as to avoid major accidents.
