Shaft Collar Types, Performances, and Design Considerations
Release Date : March 18, 2011Shaft collars are versatile components that have evolved from the basic set-screw collar to the high performing one- and two piece clamp collars. This video explains the differences between shaft collars and wraps up with an axial load comparison test. |
Transcript Set Screw Shaft Collars: The set screw shaft collars derives its holding power from a single screw as it is tightened onto the shaft. To reach maximum holding power, the shaft must be a softer material than that of the screw. The very nature of the set screw collar is its greatest fault. And as a result, the tightening of the screw causes a deformation of the material around the point resulting in a raised burr on the surface of the shaft. The damage to the shaft makes it difficult to replace or re-position the collar. Removal may require the use of specialized equipment. Due to the shaft damage, I won’t be able to reinstall or re-position the collar without the replacement of the shaft. Here are some examples of shaft damage caused by set screw collars. This type of damage is caused by multiple adjustments of the collar. And this form of damage is caused by axial movement of the collar. |
