Oil Slinger Ring Design

Ring oilers were used for medium speed applications with moderate loads during the first half of the 20th century.

Oil slinger ring design.

Our 17 000 square foot manufacturing site houses an in house foundry cutting edge technology 40 000 drawings and we can offer access to the largest inventory of. A slinger flinger disc or oil rings can also be used to provide splash lubrication. A disc is mounted inside the bearing housing and is driven by the pump shaft. Instead of greasing the part a high speed journal bearing design relies on oil lubrication.

These represented the later years of the stationary steam engine and the beginnings of the high speed steam engine the internal combustion oil engine and electrical generating equipment. An oil ring collar or a wick is typically used for supplying the oil to the bearing through the use of a pressurized system. As it rotates oil is lifted from the sump and thrown onto the inside of the housing. In pure mist lubrication the oil air mist is fed under pressure to the housing.

Oil slinger design considerations and prior art the oil slinger disc arrangement is simple to understand. Ensuring that the oil ring flinger is immersed at the correct oil level is crucial. Less frictional heat results from lower oil levels figure 2 than from an oil level reaching the center of the bearing. About two decades later in 1999 at least one major pump manufacturer saw fit to examine the situation more closely.

However pumps incorporating a two inch shaft operating at 3 600 rpm dn 7 200 would use oil rings sometimes called slinger rings to lift or spray the oil from a sump with its level maintained below the bearing. For high speed 3000 rpm and higher slinger discs or oil rings are commonly used due to the short re greasing interval exhibited with grease lubrication and the high heat generation due to churning seen with oil bath lubrication. Pumps using oil rings can suffer the following lubrication problems. A ring oiler or oil ring is a form of oil lubrication system for bearings.

Purge mist lubrication utilizes the same principles of pure mist but a reservoir of oil in the housing exists. In a comprehensive paper the manufacturer described remedial actions which included grade 46 oil viscosity and oil rings made of high performance polymers bradshaw 2000. There is no reservoir of oil in the housing and oil rings are not used. The disc outer edge is immersed some depth into the oil.
