What is “Crowning”?
– Crowning is the removal of a slight amount of tooth from the center on out to reach edge, making the tooth surface slightly convex. This method allows the gear to maintain contact in the central region of the tooth and permits avoidance of edge contact. The larger the amount of crowning, the less the amount of tooth surface contact.
Crowning is the difference in diameter between the center and ends of the roll body forming a curve in its surface. The purpose of this curve is to guarantee uniform pressure throughout its length once being subject to flexion by forces applied in its journals. Precision crowning in our corrugating or pressure rolls are always required to avoid air bags in our finished product. The precision required for this job is only obtained by state-of-the–art machinery designed specially for the task.
