In be used actually, because the link is often slightly bigger than a conveyor chain, the wear situation is serious, so the connect link became a weak spot in the whole transport chain. The main damage form for serious wear, fracture, and the reasons are mainly:

Long-term under fluctuating load, fatigue damage;

2 falls off, connecting pin or bolt looseness, failed to timely found supplement, caused by uneven or rato chain;

3, to set ring, uneven wear more serious, such as not timely replacement, prone to fracture.

After 4, the chain, can produce a lot of dynamic load and impact load, lead to transport chain velocity instantaneous large fluctuations, the transmission chain running is not smooth, so as to accelerate joint link wear or fracture;

5, production quality is poorer, wearability is poor or toughness, hardness is low, or fatigue cracks appear stress concentration, leading to insufficient strength.
