With
slinger disc lubrication, the chain operates above the oil level. The disc
picks up oil from the sump and deposits it into the chain, usually by means
of a trough. The diameter of the disc should produce rim speeds between
600 fpm minimum and 8000 fpm maximum. A collector plate is usually required
to direct the oil to the chain linkplates. See typical drive installation
using slinger disc lubrication immediately below.

Oil
Stream Lubrication. (Type C)
This
type of lubrication is required for large horsepower, high speed drives.
An oil pump should be provided to spray the oil across the lower span of
chain in a continuous stream. Orifices should be placed so that oil is
sprayed across each strand of the chain. This type of lubrication may be
used up to the maximum speeds shown in the horsepower rating tables for
each size of chain, except where the rating is zero. |
