When lubricating oil leaks on the turbine or
compressor wheel side, it will adhere to the wheel or
housing. the oil may then be contaminated with dust
or
carbon.
Such
contamination
will
destroy the balance
of
the rotating shaft and prevent normal operation.
To
prevent this problem, lubricating oil is sealed by
the follwoing parts:
On the turbine wheel side
*
A
piston ring
(1)
is placed over the shaft,
*
The shaft itself has an oil fling portion
(2).
*
A
piston ring
(3)
is
placed over the thrust sleever
(5).
*
The
oil deflector (4), which is placed
on
the thrust
sleeve
(5),
prevents oil from leaking to the piston
ring side.
In
addition, oil is prevented
from
leaking to the
outside by
a
seal ring (square rubber ring) placed
between the center housing and the back plate.
