Pumps using oil rings can suffer the following lubrication problems.
Oil slinger ring function.
Because the slinger is held only by a detent action in the rest position the slinger can be moved aside during assembly and disassembly of the companion bearing and seal structure and thereby provide greater access.
Quick video on how splash lubrication works in briggs and stratton vertical shaft engines.
An oil slinger is held in place on a shaft by an o ring which serves as a detent when the shaft is at rest and as a static seal when the shaft is rotating.
The oil slinger is a thin metal disc that deflects the oil away from the crankshaft seal.
A ring oiler or oil ring is a form of oil lubrication system for bearings.
The oil that lubricates the timing chain is pumped toward the crankshaft seal at high pressure and very high volume.
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.
Shows how the oil slinger sits in the oil sump and how the camsha.
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.
A slinger flinger disc or oil rings can also be used to provide splash lubrication.
Not all versions of constant level oilers will serve the reliability focused user well.
Purge mist lubrication utilizes the same principles of pure mist but a reservoir of oil in the housing exists.
Ring oilers were used for medium speed applications with moderate loads during the first half of the 20th century.
Less frictional heat results from lower oil levels figure 2 than from an oil level reaching the center of the bearing.
All of these conditions can result in insufficient lubrication from the oil ring.
Bath with slinger ring.
12 to 25 inches from the lower edge of the flinger or above the lower edge of the bore of the oil ring.
This paper seeks to reprise the work of lemmon booser heshmat pinkus gardner and ettles et al in defining.
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.
There is no reservoir of oil in the housing and oil rings are not used.
Beware of oil sumps with incorrect oil viscosity or with varying depths of oil ring immersion or incorrect roundness or rough surface finish of the slinger ring.
