EVERCOOL's
Research and Development team has created the Air sealed shaft
fan. It has ready made an impact to the market. This kind of
shaft structure is very cost efficient (low material cost and
a longer life span than the traditional shaft.) The features
are as follow:
Design
Principle: |
|
The
sealed bearing is composed of five components including
the oil cap, copper bearing, plastic washer, mylar piece,
and o-ring; wherein the components can effectively prevent
the oil from leaking through the top part of the bearing.
At the bottom of the fan, the sealed single-piece mechanism
can completely seal the oil within the fan structure without
leakage. The copper bearing used for the fan unit can
reduce the amount of oil spreading, effectively retaining
the proper amount of oil in the fan for a long period
of time to increase the lifespan and reduce the noise.
However, EL bearings are achieved by injecting a sufficient
amount of oil into the copper bearing<and fulfill oil
space>, and then sealing off the top and bottom parts
of the bearing to prevent the oil from leaking, thereby
improving the lifespan of the fan unit. As the bearing
is sealed, dust can be effectively stopped at the top
or bottom of the bearing to prevent malfunction of the
fan unit due to dust accumulation. |

Concept: |
|
EL: Completely sealed bearing structure ¡÷No
mechanical contact during usable lifespan of fan ¡÷No
oil loss ¡÷Oil quality not degraded
|
Comparison
between EL bearing and sleeve bearing: |
|
 |
Sleeve bearing has a simple structure with only
an o-ring at the tip of the fan to prevent oil from
spreading. |
|
 |
EL bearing has the o-ring at the tip of the fan
and the single-piece fan base in addition to the
seal mechanism (rubber washer, o-ring, mylar piece,
copper cap) to effectively reduce the risk of oil
leak and improve the fan lifespan. |
