Company History
Started in 1993, Quality Transmission Components is an
operating division of Designatronics, Inc. Since its inception
in 1960, Designatronics serves a worldwide customer base in
excess of 15,000 firms ranging from Fortune 100 companies
to individual inventors. The company occupies 139,000 sq.
ft. of warehouse and manufacturing space on Long Island,
New York.
In 1993, the combination of an ever-increasing demand
for metric gears and a strong growth in demand for power
transmission products spawned Quality Transmission
Components. Designatronics capitalized on its relationship
with Kohara Gear (KHK), and Quality Transmission
Components became the exclusive North American distributor
of their complete product line. In 2006, Quality Transmission
Components shipped over 30,000 metric gears to users,
making us the largest supplier of stock metric gears in the
United States.
In 2000, Quality Transmission Components saw the
opportunity to expand our product line. We added the
Zetasassi line of belt and chain tensioners. We then added
neoprene timing belts, aluminum, steel and nylon timing
pulleys, roller chain and planetary gearheads. We also
became a distributor of Davall Stock Gears representing
their inch gear line in the North American marketplace. All
of these products are marketed under the Econobelt™ brand
name.
Quality Transmission Components' selection of off-the-shelf
power transmission components now includes almost 13,000

QTC Stock Gear Selection Methods
Please refer to this page when you are selecting gears.
Selecting Gears Based on Gear Strength
Step 1
Approximate the type of gear, strength and torque load.
Definition of Bending Strength
Definition of Surface Durability
The allowable bending strength of a gear
is defined as the allowable tangential force
at the pitch circle based on the mutually
allowable root stress of two meshing gears
under load.
The surface durability of a gear is defined as
the allowable tangential force at the pitch circle,
which permits the force to be transmitted safely
without incurring surface failure.
Step 2
Example of the defacement
due to insufficient surface
Make a tentative selection based on the torque load using the KHK catalog or the Web catalog. durability.
Example of the failure due to
insufficient bending strength.
■ The KHK catalog is used for the tentative selection.
Step 3
■ The Web catalog is used for the tentative selection.
After calculating the required strength using the actual conditions of usage, examine the selection made in Step 2.
The formal strength calculation can be performed using the various
formulas.
If the Web catalog is used, the strength can be
easily confirmed.
(2) Equation - Bending Strength
In order to confirm an acceptable safe bending strength, it is
necessary to analyze the applied tangential force at the working
pitch circle, Ft, vs. allowable force, Ftlim. This is stated as:
Ft ≤ Ftlim
(1.4)
It should be noted that the greatest bending stress is at the root of
the flank or base of the dedendum.
Then Equation (1.4) becomes Equation (1.5)
Ft≤ sFlim
(1.5)
Equation (1.6) presents the calculation of Ftlim:
mnb KLKFX 1
Ftlim = sFlim ––––––– (––––––) –––
(kgf) (1.6)
YFYeYb KVKO SF
Equation (1.6) can be converted into stress by Equation (1.7):
YFYeYb KVKO
sF = Ft –––––– (––––––) SF
(kgf/mm2) (1.7)

QTC Stock Gear Selection
There are many ways to select gears depending on which parameters are more
important than others such as the strength, size, precision, and speed ratio. As
a guide, we have introduced "Selecting Gears Based on Strength" and "Selecting
Gears Based on Use".
Selecting Gears Based on Use
Example 5: Cost performance
Example 1: High Speed Rotation
For applications requiring noise and vibration reductions in high speed gear
drives, we recommend the ground gears (items with letter G in catalog
numbers). Using helical gears will increase the contact ratio, leading to smoother
transmission.
Example
The more production steps, the higher the cost. For example, the SS series which
goes thru steps of - raw material, turning, gear cutting, and black oxide - has
excellent cost-performance ratio. The Injection Molded Gears and Sintered Gears are
also products with high cost-performance figures due to mass production.
■ MSGA Ground Spur Gears
JIS N5 Class (OLD JIS1)
Overall carburizing
Example
■ SS Steel Spur Gears
■ DS Injection Molded Spur Gears
■ LS Sintered Metal Spur Gears
■ SSG Ground Spur Gears
JIS N7 Class (OLD JIS3)
Tooth surface induction
hardened
Example 2: High Strength (compact design)
Example 6: Availability of Secondary Operations
Generally, the size of gears is proportional to load capacity. To make the design
compact requires the use of alloys (SCM415, SCM440) with heat treating. We
recommend catalog parts that start with letter M or K.
Please note that heat treated items have hard surfaces. While they gain the strength,
they lose the ability of secondary operations to be performed.
Example
Overall carburizing (Secondary operations
not possible)
■ SSG Ground Spur Gears
Tooth surface Induction hardened
(Secondary operations possible except the
tooth)
■ SS Steel Spur Gears
No heat treatment (Secondary operations
possible)
Example
SCM415 overall carburizing
■ KHG Ground Helical Gears
Tooth surface induction
hardened
Example 7: High Reduction Ratios
Example 3: Backlash Considerations
In order to minimize the backlash, use high precision parts with ability to adjust center
distances. KHK carries, as standard products, items with ability to adjust backlash such
as Tapered Racks and Pinions and Duplex Worms and Worm Wheels.
We recommend the use of Worm Gear Pair or High Ratio Hypoid Gears.
It is also possible to obtain high reduction ratios by forming planetary gear
systems using spur and internal gears.
Example
■ Worm Gear Reduction Ratios
1/10、1/15、1/20、1/30、1/40
1/50、1/60、1/80、1/100、1/120
Example
■ Tapered Racks & Pinions
KTSCP, STRCPF
■ High Ratio Hypoid Gear Reduction Ratios
1/15、1/20、1/30、1/45、1/60
1/90、1/120、1/180、1/200
■ Duplex Worms, Worm Wheels
KWGDL(S), AGDL
Example 4: Calculating and Positioning
Example 8: Rust Prevention
It is very convenient to use CP Racks and Pinions for positioning applications. We
recommend using ground gears for use in calculating to reduce pitch errors.
Stainless steel and plastic material are suitable where rust will cause problems such
as in food and chemical processing equipment. KHK uses these materials in the
manufacture of many kinds of spur, rack, miter, bevel, screw and worm gears.
Example
■ SSCPG CP Ground Spur Pinions
SSCPG10-20
JIS N7 Class (JIS B1702-1;1998)
■ KRGCP CP Ground Racks
