Flanging Processes

Roll Staking:

Roll staking is an excellent way of attaching flanges to smaller timing pulleys. Roll staking produces a crimp 100% of the way around the edge of the flange. This method is superior to conventional staking methods which only hold a small percentage of the flange to the pulley.

Heat Shrinking:

Heat shrinking is an excellent way of attaching heavy large diameter flanges to timing pulleys. The flanges are heated to 450 degrees Fahrenheit or more and then placed onto the pulleys’ flange step which is 0.015” to 0.020” larger in diameter than the ID of the flange in its cold state. Upon cooling, the flange shrinks onto the flange step of the pulley, permanently holding it in place.

Bolt on Flanges:

For the ultimate in flanges, IPG makes bolt on flanges. These flanges are the heaviest and most durable flanges available. Flanges are held to the sides of the timing pulleys by flat head screws. An additional advantage to bolt of flanges is the ability to remove the flange for belt maintenance. Other flanging methods do not allow the flange to be removed for maintenance purposes.

Comparing Nylon and Metal Pulleys

When it comes to something like pulleys, their brilliance truly is in their simplicity. They’re used to reduce the effort required to lift heavy objects or change the direction of the force you’re applying. They are also commonly used throughout various manufacturing and construction industries. Because pulleys are nothing if not versatile, they are typically…

Identifying and Replacing a Machine’s Timing Belt

Regardless of the type of equipment you’re talking about, all machines in a manufacturing environment should be subject to a proactive maintenance program. By addressing a small problem today, you can stop it from becoming a much bigger (and more expensive) one down the road – saving your business a lot of time and stress…
