Like any power transmission component, a roller chain requires the careful and accurate installation to ensure trouble-free operation and long life. Though roller chain installation is a fairly simple process, certain precautions must be taken and maintained in order to achieve the desired results. The following are the installation method and inspection items of the roller chain.

Roller Chain Installation 

You will need an angle grinder, chain vise, punch or chain screw, hammer, and either a straight edge, level, or laser alignment tool.

(1)Grind the riveted portion of the two pins with the angle grinder (remove the cotter pins if necessary).

(2)Secure the chain in the chain vise. Use the primary and secondary punch (or chain screw) and remove one set of pins.

(3)Check both parallel shaft alignment and sprocket axial alignment using a straight edge, level or a laser alignment tool. Misalignment results in uneven loading across the width of the chain and may cause roller link plate and sprocket tooth wear. Remember to place the sprockets as close to bearings as possible.

(4)Install both ends of the chain onto the sprocket and join with the connecting links, then fastened by a spring clip or cotters (it may be necessary to have assistance to support the chain as the connection is made).

The Inspection of Post-Installation 

After installing the chain, you must check the accuracy of the installation. Verify the amount of slack and the precise positioning of the shafts.

1.Some form of chain length adjustment must be provided to ensure maximized chain life, preferably by moving one of the shafts. Chain slack should be about 4-6% mid-span movement in horizontal drives and 2-3% in vertical drives.

2.Giving the chain a short test run is important. This is not only to see if the installation was successful but to also regulate oil delivery to the chain.

3.When inspecting the chain, be sure to check for the following conditions.

(1)Cracks in the rollers

(2)Cracks in the link plates

(3)Rotated Pins

(4)Wear on the end surfaces of the link plates

(5)Loud noises or excessive vibrations in the chain

If you find any of these conditions, take immediate steps to correct the problem.

(1)Ensure that the roller chain, sprocket, and other parts are in good condition

(2)Align the shaft and sprocket correctly

(3)The chain tension needs to be appropriate

(4)Provide adequate lubrication

After the roller chain is installed, it needs daily lubrication and maintenance to prevent the chain from accelerating wear and shorten the service life.
