Gear Blank
In
a typical manufacturing cycle the gear blank goes through many processes
from being transformed from the raw material to the final end product.
Actually the gear blank is the work piece which is processed to give the
final shape of gears. A lot of things goes into making a quality gear blank.
Materials for Gear Blanks
Most of the gear manufacturing companies maintain a large number of gear
blank inventories. Typical materials used are low carbon steel, high grade
carbon steel, Aluminum Gear Blanks, Stainless Steel Gear Blanks, Brass Gear
Blanks. Gear blanks can be of various diameters and thickness. Those that
are engaged in the manufacture of gear Blanks can make them available in
various forms. Typical examples range from completely machined gear blank,
with or without keyways. Other options of gear blanks include saw cut stock,
or even semi finished to meet the customers needs. Today with the advancing
technology the nonmetallic gear blanks are also used plastic gear blanks are
very popular.
Selecting the Correct Material
A correct gear blank should have a correct wall thickness. This ensures the
wall thickness between the tooth root diameter and outside diameter of the
metal core is just right.
For
select the suitable core size of the gear blank please ensure the following
things:
- Authentication of the bore dimensions including the keyway.
- Making sure the top of the keyway does not intersect the metal core
OD.
- For optimal use, the metal core should be around half of the gear's
OD.
Knurled Core
The knurled core in the gear blank comes with many good features. They
provide high torque transmission. Also, they can even perform heat
dissipation from the shaft to the metal through the gear teeth. The knurled
core has virtually replaced conventional options like the hexagonal or the
round notched metal core. Another distinct advantage is the closer minimum
wall thickness in context to both bore and root diameter, this is especially
profound in border line cases. The following image shows the different types
of cores:

Manufacturing of the Gear Blanks
Gear Blanks are today made with a number of technologically advanced
techniques that offers many advantages including increasing the material
strength to withstand the tremendous stress and strain of highly critical
gear operations.
