One of the most important factors to consider when choosing the right roller chain for your machine is size. Using the wrong size roller chain can result in reduced performance, increased wear, and even complete machine failure. Here’s how to determine the proper roller chain size for your application:
1. Count the number of balls
Pitch is the distance between the centers of two adjacent Roller Pins. To determine the pitch number, simply count the number of roller pins in the chain. Make sure to only count full roller pins – not half pins or connecting links.
2. Measure the diameter of the roller
The roller diameter is the distance between the highest point on one roller and the highest point on the opposite roller. This measurement will determine the roller chain pitch. Be sure to measure several points along the roller to ensure accuracy.
3. Calculate the roller chain pitch
Once the number of pitches and the diameter of the rollers are known, the roller chain pitch can be calculated. To do this, divide the drum diameter by 2, then multiply the result by the number of pitches. For example, if the rollers are 0.5 inches in diameter and there are 48 pitches in the chain, the pitches would be:
(0.5 ÷ 2) x 48 = 12 inches
4. Check roller chain elongation
Over time, roller chains stretch and elongate, which can affect their overall performance. To determine if your roller chain is stretched, you can measure the overall length of the chain. If it is more than 1% longer than its original length, it is likely that the chain has stretched and should be replaced.
5. Consider Load Requirements
The load requirements of your machine also play a role in selecting the proper roller chain size. Be sure to consider factors such as weight, speed and torque when selecting a roller chain.
6. Consult a Professional
If you are still unsure which roller chain size to choose, consider consulting a professional. They can help you decide which machine is right for you and make sure it performs as expected.
In summary, selecting the correct roller chain size is critical to ensuring optimum machine performance and service life. By counting pitch numbers, measuring roller diameters, calculating roller chain pitch, checking roller chain elongation, considering load requirements, and consulting a professional, you can choose the ideal roller chain for your application.
