De’Ran Gearbox Rebuild, Repair, and Emergency Services
Once your De’Ran gearbox arrives at our
facility we disassemble, clean, inspect and measure all
gears and shafts and determine if your De’Ran gears and
shafts are qualified to be repaired. If the De’Ran gears
and shafts are not repairable, we have the
capabilities and expertise to manufacture all new De’Ran
gears and shafts such as Helical, Double Helical,
Herringbone, Split Herring bone, Bevel, Spiral Bevel, Spur
Gears, Ring Gears, Eternal Ring Gears, Rack & Pinion, Worm
Gears, Double Enveloping Worm Gears, Hypoid Gears, Screw
Gears, Plus More! Once your
De’Ran gearbox is repaired we then do a six hour
test run for overheating, vibration, and leaking to ensure
our 24 Month Guarantee. National Gear Box Repair can do all
of these repairs and rebuilds at a considerable amount of
saving rather than buying a new De’Ran gearbox.
De’Ran Gear Inc
De’Ran Gear produces some of the most notable and recognizable gear drives since the
1950’s. In 1951 Don Randolph was designing and building gear drives for the most intensive
applications. The designs were groundbreaking at the time and the original Gear Case design
has still been used in the production of the De’Ran Gearboxes due to its size.
De’Ran Gear Inc
has produced more than 170,000 Gear Drives for the international market in six continents and
is still continuing to produce new and modern designs that are continuing to improve on
reliability and efficiency out of North County Road in Lubbock Texas.
De’Ran gearboxes have always been constructed with Spiral Bevel Gears that are case
hardened for long lasting endurance and matched and lapped in sets to ensure a quiet
operation. The Bearings are all precision ball and roller styled bearings that are sized to produce
efficiently and reliably for a long time. Because of this the bearing life of De’Ran Gearboxes
often exceed AGMA standards. The size of the Deran Gear Drive requires large shafts for rigid
position of the gear set and high security safety factors needed for the transmission of torque
without wear and tear.
De’Ran Gear Inc Also has been producing Fan Cooling Gear Drives To reduce oil temperature
by 20 degrees or more. This operational technique has been a staple of De’Ran Gearboxes for
over 30 years and aids in doubling the life of the lubricating oil. De’Ran Gearboxes all benefit
from having fan cooling FREE on all De’Ran Gear Drives. The De’Ran Gearbox is utilized for
vertical pumps of all types driven by horizontal engines or motors. They're available in all ratios
with engine speeds of 800 to 2600 RPM and pump speeds of 300-3600 rpm.
