The Best Methods of Attachments for Standard and Custom Couplings

In our catalog couplings, and on most of our custom products as well, we offer different types of attachment features. The two most common end attachments are the integral clamp and set screw styles. We would like to provide you with the information you need to make the right choice for your application. Integral Clamp Ends When using a clamp attachment, the shaft is held in by tightening the cap screw and transmitting torque against the shaft through friction. A benefit of this method is that removing the coupling is very easy. Simply loosening the cap screw allows the shaft to easily slide out. Set Screw Ends When using a set screw attachment, there are set screws that will come down and bear directly on the shaft. The drawback to using a set screw attachment on a typical, round shaft with no flats is the screws can sometimes create a burr on the shaft. When you go to remove the shaft, the burr can become lodged in the set screw hole, making the coupling more difficult to remove. Also, if an application has a lot of starts and stops, the screws can sometimes begin to loosen up. Once that begins, it will progressively transfer less and less torque. The key to using a set screw attachment is to make sure that your shaft has a flat that lines up with the set screws. Running the screws down onto a flat surface gives you a much more positive attachment. For more information, visit: http://www.heli-cal.com
