Sprockets : Installation & Care :

Proper sprockets are another consideration. Roller chain sprockets must fit your chain perfectly if you wish the chain to function as it should. You should be able to find gears and sprockets to match your chain type and size, whether you are producing your own machine or replacing the parts inside an existing machine.

Sprocket Matching :

Many roller chains are used improperly with sprockets that fit to a degree, but not perfectly. Your chain is not designed to function on sprockets that are too big or too small, no matter how slightly. The roller chain sprockets must fit into each groove perfectly, and they must not leave any slack as the chain rolls over the sprockets.

Sprockets that are too small may not catch the chain with every turn, and sprockets that are too big will cause wear on the chain that could break it prematurely. You are rarely in danger of breaking your chain, unless the sprocket is too large. If you are not careful, the sprockets you use will not hit the chain in the right places. A chain that is a bit too tight could break your sprockets or run inefficiently. A chain that is too large will simply miss the sprockets as it turns. The motor will use energy, but the system will not function properly.

Clearly, you must choose sprockets measured and rated for your roller chain. Some chains are sold with accompanying sprockets. You may check the rating on the chain to buy extra sprockets, or you may purchase sprockets that match those that came with the chain on your original purchase. You may think of the sprockets as a secondary item, but sprocket matching to your chain will keep it in good condition.

Installation :

Sprockets that are used in your machines or industrial devices must be handled with the same care you handle each chain. The chains you use interact with your sprockets on a surface level. The two items must work closely together, and you should not mishandle the sprockets before you get started on your work.

The sprockets you are installing must be installed with the greatest care possible. Every tooth on the sprocket must be aligned. Be cautious: bending the teeth will cause a lack of alignment in the system. One damaged sprocket tooth could destroy the efficiency of a system, or the sprocket tooth could eat away at the chain until the chain breaks.

Slowly screw in the sprocket until the screw it tight, but do not tighten the screw too much. The screw could break the face of the sprocket, and you will lose the integrity of that piece of the system. You must carefully remove screws when adjusting the system, and then you can adjust each part of the system without causing further damage.
