Abstract
Lubrication plays a decisive role in performance and operating costs of rolling bearings. Oil lubrication, which initially may be more expensive than grease lubrication, can provide longer maintenance intervals and reduce total cost of ownership, especially in case of unfavourable operating conditions. In this context, oil lubrication including a simple designed ring lubricator for oil supply, might be an economic choice for industrial operators. This paper comprises results of oil analyses obtained within a 6 000-hour long-term test featuring an oil lubricated rolling bearing arrangement equipped with a ring lubricator for oil supply. Periodically taken oil samples show changes in oil condition during the period of operation and reveal impacts on the oil caused by the ring lubricator. Crucial design criteria of a ring lubricator influencing operating characteristics of the ring and thermal behaviour of the rolling bearing are presented and evaluated regarding effects on service life of oil. Based on the data provided by the oil analyses accompanied by a final optical inspection, attainable service life of the oil is specified and compared to the relubrication interval of a grease lubricated bearing running under identical conditions. The central objectives of the presented study are to prove and quantify the benefits of using a ring lubricator in rolling bearing arrangements concerning maintainability compared to a grease lubricated rolling bearing and to identify crucial design characteristics of the ring lubricator influencing service life of the oil.
