The STD-RCF 3 Rolling Contact Fatigue Machine is a modified version of the STD-TE 73H Two Roller Machine. It provides a three roller test configuration similar to the now obsolete GE Polymet machine. Two large diameter rollers are loaded diametrically opposed against a small diameter rod specimen. In the original Polymet design, the latter was driven. In the current design, the two outer rollers are driven, allowing much higher rotational speeds to be achieved, while at the same time substantially eliminating potential slip in the roller contacts.
The machine is designed for performing rolling contact fatigue tests under conditions of elastohydrodynamic lubrication, with well filtered lubricant feed, thus minimizing the potential for adhesive, abrasive or oxidative wear or surface propagated micro-pitting; the intended failure mechanism is thus by pressure generated, sub-surface propagated, flaking or spalling.
