GL type roller chain coupling

Main features of GL roller chain coupling:

Roller chain couplingIt has the advantages of simple structure, convenient assembly and disassembly, large transmission torque, high efficiency, and reliable work.However, the wear between the chain and the chain is large, especially when the radial movement caused by the centrifugal force will accelerate its wear at high speeds, it is not suitable for use at high speeds and impact loads, and it is not suitable for vertical shafts. Join.

When designing the overall structure of the coupling, full attention should be paid to the lubrication and dust prevention between the tooth surface and the roller, and a casing is added.In addition to preventing dust and oil, it also has a protective effect.Because if the chain breaks, it may cause a personal accident.

The double-row sleeve roller chain chain coupling has become a standard (old standard GB6069-85, new standard GB/T 6069-2002).The transmission torque and allowable speed are respectively four times and two times that of a single-row roller chain of the same size.Because when the chain size is used, two teeth can be accommodated in the width of a single-row sleeve roller at the same time, while a double-row type can only accommodate one tooth, so the tooth thickness of a single-row is only half of that of a double-row.Therefore, the rollers of the double-row chain are respectively in the tooth grooves of the driving and driven sprocket, and each independently rotates and does not interfere with each other when subjected to force, so that the wear is greatly reduced.
