-
The
shaft lines should be kept concentric when
the coupling is connected with a motor. The
installation error should not bemore then
the tolerance value of the coupling.
-
When the output shaft is installed with the
coupling or belt wheel, they should be pressed
into the screw hole on shaft end, or assembled
by heating. No hammering should be done on
it.
-
The
mechanical stepless speed variator is not
used in such a occasion where overload or
running-blockage happen to occur.
-
Speed-regulation
should be effected in running. No turning
the hand wheel of speed-regulation when the
machine stops.
-
The
banking screws of speed-regulation on tow
ends under the operating box are well adjusted.
Please don’t touch them.
-
This
set is not suited to work in the environment
of above 40 C, especially more than 45 C when
the temperature goes up.
When the variator starts to work (without
load), the temperature rise higher than normal,
up to 40~50 C above the environment temperature.
After 60-80 hours running, the temperature
will decrease gradually. Finally, the temperature
will be about 20 C higher than surrounding
and keep stable. The high temperature at beginning
do not damage any parts of variator and do
not effect its service life. (Suggestion:
running without load at first.)
-
The
liquid lubricating oil is used for the speed
variator. Its trade mark is Ub-3. Please check
up the oil level before use.
-
The
machine is filled with lubricating oil before
leaving the factory. When it starts to work
up to 1000 hours for the first time, its lubricating
oil should be replaced.
-
The
lubricating oil level inside the speed variator
should be kept at the height of one-third
in the oil scale. Users should usually check
up the height of oil level.
It is strictly prohibited to operate it short
of lubricating oil. The air screw nut on the
operating box is screwed up for preventing
from oil leakage in moving when leaving the
factory.
It should be loosed when it start to run.
It is strictly forbidden to use it before
loosing.
