Section II Mounting of the Engine and
Coupling of Driven Machine with the Engine
A.Mounting
of
the Engine
The engine should be bolted
down
to
a rigid base with the same mounting dimemsions as
the diesel engines of its kind(see the drawing of overall and mounting dimensions of the enigne).
The axial dimensions of the pulley of the driven machine should coincide with that of the engine
to
avoid torsion of the V-belts.
The engine and driven machine should be in
good
coupling.Protection measures of the
flywheel and belt pulley should be taken
to
avoid danger.
B.Selection
of
the Size of the Pulleys
When the engine
IS
used
to
drive working machines,the user should make a correct selection
of the size of pulleys
to
ensure normal operation of the engine and driven machines.The size of
pulleys
may
be calculated according the following formulas:
Where Dhis the diameter of the pulley on the engine shaft(use pitch diameter in case V-belt is
used) ;
D
2
,the diameter of the pulley on the shaft of the driven machine(use pitch diameter in
case V
-belt
is
used);
nl
,the rotative speed of the engine;
n2,
the rotative speed of the driven machine.
One piece of
V-belt
pulley,148mm in outer diameter,is attached
to
the engine on its delivery
from
the maker's works.Pulleys of special specifications
may
be provided through negotiation when
customer place an order. (Don't increase the diameter
to
get more efficiency and higher speed.Our
company will not .bear three guarantees responsibility for this)
