Abstract

There is a range of mechanical components in tribological systems that operate under oscillatory sliding contact. An example of interest is the so-called pin-bushing joint interface that is typically lubricated with grease. Pin-joints are often heavily loaded and the relative sliding motion at the interface between the pin (shaft) and inner surface of the bushing generates considerable amount of heat. As a result, the surface and near-surface materials can quickly deteriorate and often trigger premature catastrophic failures. Nevertheless, the severity of the temperature rise is strongly dependent upon a series of design factors including various geometric variables, materials properties, and operating conditions. In this paper, the development of a fractional factorial experimental design for evaluation of the effect of five important design factors in pin-bushing assembly is reported. The factors of special interest include the clearance ratio (C/R), aspect ratio (L/D), oscillating angle, RPM, and applied load. The performance response is the interface temperature rise. The factorial analyses presented provide quantitative information on the factors that tend to have the greatest influence on the thermal behavior of a pin-bushing assembly. Copyright © 2006 ASME.
