.Introduction to round link chain
.Round link chain is suitable for coal mine scraper conveyor, coal plow, drum mining Traction chains for coal machines and other machinery, etc. Ring chain quality assurance, customized processing, in stock, reasonable price, China Coal will relieve your worries!
.Round link chain compliance conditions and failure analysis
.． Eligible conditions
.The eligible conditions for circular link chains are:
.Withstand tensile force
.Fatigue caused by pulsating load
< br/> . Friction and wear occur between chain rings, between chain rings and sprockets, between chain rings and middle plates and grooves
. Made of coal powder, rock powder and The action of moist air causes corrosion.
.． Failure analysis
. The breaking forms of circular link chains are roughly divided into:
. The load of the chain exceeds its own static breaking load, causing premature breakage. This kind of breakage It mostly occurs in the defective parts of the chain link shoulder or straight arm, such as crack welding heat affected zone and individual bar cracks
After running for a period of time, the chain will not reach the breaking load due to fatigue. This kind of fracture mostly occurs at the connection between the straight arm and the arc of the chain link.
.Requirements for circular chain
.With the same material and cross-section, it must have a higher load-bearing capacity
.With the At the same time, a larger breaking load must have a larger elongation
. There must be smaller deformation under the maximum load-bearing capacity to ensure good meshing
.Has higher fatigue strength
.Has higher wear resistance
.Has higher toughness and greater ability to absorb impact loads
.Geometric dimensions comply with drawing requirements.
.This product has been exported to the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran and other countries, and has won unanimous praise from customers.
