ErieTec Educates: How To Tension Your Belts

Summary

In this video, Erie Tech demonstrates how to save time, money, and energy by properly tensioning v-belt drives. The importance of correct belt tensioning is highlighted, as it ensures better torque transmission, prolongs the lifespan of belts and shivs, and minimizes downtime and spare part costs. Two methods for proper tensioning are discussed: the force deflection method using a tensiometer and the elongation method with a Timken tension finder. Both techniques help ensure optimal belt performance, maximizing uptime and efficiency. Erie Tech offers further assistance through their local branches.

Takeaways

• 😀 Proper belt tensioning is crucial for optimal performance of v-belt drives in various industries.
• 😀 Correct tensioning ensures better torque transmission, leading to longer life for both belts and shivs.
• 😀 Proper belt tensioning can reduce downtime, saving money, time, and energy in the long run.
• 😀 The first method to measure belt tension is the force deflection method, using a belt tensiometer.
• 😀 To use the force deflection method, you need to know the distance from the drive to the driven shiv and multiply it by 1/64th.
• 😀 The second method is the elongation method, using a Timken tension finder.
• 😀 With the elongation method, you need to remove slack, scribe a line on the belt, and use the tension finder to determine proper tension.
• 😀 The tensioner’s chart helps in determining the correct slot for the tension level of the belt.
• 😀 After adjusting tension, tighten the bolts to secure the system in place.
• 😀 Proper tensioning maximizes uptime, reduces spare part costs, and ensures the longevity of the belt system.

Q & A

Why is proper belt tensioning important in V-belt drives?

Proper belt tensioning ensures better torque transmission, leading to longer life for both shivs and belts, which results in increased uptime, reduced spare parts costs, and energy savings.

What is the force deflection method used for?

The force deflection method is used to measure the correct belt tension by applying force to the belt and using a belt tensiometer to determine whether the tension is within the proper range.

What equipment is required for the force deflection method?

The key equipment required for the force deflection method includes a belt tensiometer and a few critical measurements, such as the distance from the drive to the driven shiv.

How do you calculate the required force deflection value using the force deflection method?

First, you measure the distance from the drive to the driven shiv, multiply it by 1/64th, and set the corresponding o-ring on the tensiometer. Then, you apply force to the belt, leveling it, and compare the force value with a provided chart to determine if the tension is correct.

What is the elongation method for belt tensioning?

The elongation method uses a Timken tension finder. It involves placing the belt on the shivs, removing slack, scribing a line on the belt, and measuring the belt's elongation to ensure proper tensioning.

What is the first step in the elongation method?

The first step in the elongation method is to place the belt on the shivs and remove any slack from the system.

How do you measure belt tension using the Timken tension finder?

To measure belt tension with the Timken tension finder, you scribe a line on the belt, clip the tension finder to the belt, and scribe a second line on the opposite end. You then use a chart to determine the correct tension slot and adjust the system until the mark aligns with the proper slot.

What should you do once the correct belt tension is achieved using the elongation method?

Once the correct belt tension is achieved, you remove the tension finder, tighten the system's bolts, and ensure everything is secure and ready to operate.

What are the benefits of properly tensioned V-belt drives?

Properly tensioned V-belt drives offer longer belt and shiv life, reduced maintenance costs, improved uptime, and energy savings.
