Helical Gear Boxes
(Industrial) Sections :-
a) Toughened
b) Hardened & Ground |
|
Some
salient Features Of Helical Gear Boxes (Industrial)
are :
Casing: Cast Iron
inoculated for grain refinement, for small and medium size units
and of steel fabricated (By M.I.G. Welding) duty stress relieved
for large size units. The stress zones are amply ribbed against
distortions under dynamic load.
Gearings: Helical
and spiral bevel gearing are provided with addendum correction
based on latest scientific findings. Gears made of Chrome Nickel
Molybdnum steel are integral or alloy steel rings shrink fitted
onto cast iron or cast steel centres. The internals are heat
treated upto 300 BHN for pinions and upto 260 BHN for gears
prior to teeth cutting.
Shaft Extensions:
Provided with long holes at ends and grooves under bearing seats
for removal of Bearings & Couplings with S.K.F. hydraulic
injection system. The Shaft ends are of "u6" tolerance
for recommended shrink fitted couplers and to "n6"
tolerance for key fitting.
LUBRICATION:
Forced lubrication or scrapers are provided on both sides of
gear for positive flow of oil into the
the bearings in either direction of rotation.
COOLING: Unibuilt
cooling coils or external heat exchangers are provided where
required.
We
can also supply hardened and ground gear boxes in our range.
