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.
Oil slinger ring function.
There is no reservoir of oil in the housing and oil rings are not used.
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.
The oil slinger is a thin metal disc that deflects the oil away from the crankshaft seal.
Pumps using oil rings can suffer the following lubrication problems.
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.
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.
Purge mist lubrication utilizes the same principles of pure mist but a reservoir of oil in the housing exists.
The sole function of purge mist is to protect against contaminants by maintaining a slight positive pressure in the headspace above an oil.
Ring oilers were used for medium speed applications with moderate loads during the first half of the 20th century.
A ring oiler or oil ring is a form of oil lubrication system for bearings.
A slinger flinger disc or oil rings can also be used to provide splash lubrication.
12 to 25 inches from the lower edge of the flinger or above the lower edge of the bore of the oil ring.
Less frictional heat results from lower oil levels figure 2 than from an oil level reaching the center of the bearing.
Not all versions of constant level oilers will serve the reliability focused user well.
Bath with slinger ring.
And that slinger sits between the timing chain and the seal and keeps a lot of the oil from pounding directly on the seal.
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.
The oil that lubricates the timing chain is pumped toward the crankshaft seal at high pressure and very high volume.
All of these conditions can result in insufficient lubrication from the oil ring.
