Arrow Gear's On-Demand
Program for Ground Tooth Spiral Bevel Gears
Developing a new spiral bevel
gear design from scratch is very costly, and the process can take months.
However, by using Arrow’s On-Demand Program for ground tooth spiral bevel
gears, the customer can take delivery in a matter of days.
Arrow believes that its On-Demand product line, which offers a cost saving
alternative, will help manufacturers in their efforts to gain a
competitive edge.
Arrow’s On-Demand product line includes a full variety of ground tooth
spiral bevel gears. This positions Arrow Gear as the only gear producer in
the world to provide such a diverse selection.
For manufacturers of power transmission systems, utilizing Arrow’s
products in prototype development and low-volume production runs can save
literally tens of thousands of dollars.
“Our On-Demand product line is unique for several reasons. First, no one
else in the world offers stock ground tooth spiral bevel gears in the
variety that we do. Secondly, our engineers are available to assist with
modifications to the contact pattern and other physical attributes to meet
the customer’s specific requirements. And by using our stock gears,
customers can save a great deal of expense,” stated Arrow’s CEO and
Chairman of the Board, James. J. Cervinka.
Arrow’s On-Demand product line features the following:
• 57 different combinations of ground tooth spiral bevels.
• Sizes up to 16 inches in diameter.
• Quality levels up to Q13.
• Parts are carburized and hardened, as opposed to through hardening,
which is common for most stock gears.
Arrow’s On-Demand gears can be modified extensively by Arrow’s engineers,
while still serving as a dramatic cost-saving alternative to
custom
gearing.
Modifications to the blank, in order to meet the customer’s gearbox
envelope requirements, can often be completed in just two weeks. In
addition, only the teeth are carburized and hardened, which simplifies the
modification process.
Modifications to the contact pattern can be performed to account for
gearbox deflections. Working with technical data provided by the customer,
Arrow engineers have the capability of performing contact pattern
development utilizing specialized software for fully loaded tooth contact
analysis and finite element analysis. While this process will obviously
take more time than modifications to the blank, the customer will still
realize significant savings from both a time and cost perspective.
“Developing a new spiral bevel gear design from scratch is very costly,
and the process can take months. Using our On-Demand products, the
customer can take delivery in a matter of days. And even when the gears
are modified, the customer can save up to 50 percent in comparison to
other costly alternatives for prototype or low-volume production runs. In
today’s market, the ability to get your product to market faster than the
other guy is a strong component for edging out the competition. Another
point is that with the flexibility of our On-Demand gear products,
engineers now have the choice of using high-quality precision gearing in
their prototype phase. Even in aerospace applications, our products can be
used for the initial testing of their application without the months of
waiting for a completely new design,” Cervinka explains.
Arrow has offered stock gears for many years. In the past, the stock gear
product line consisted of only a few ground tooth sets while the majority
were lapped gears for less-critical applications. However, there are new
challenges facing manufacturers including:
• The need for lower costs.
• Shorter lead times.
• Quality improvements, yielding…
- increased life.
- quiet operation.
- smooth-running systems for registry or
positioning.
Arrow’s decision to expand its line of precision stock gears is in direct
response to these challenges facing manufactures.
“With a product line such as this, with its inherent benefits for
prototype and low-volume production, we feel that our customers will find
it to be a valuable solution, and one that will fill a rather substantial
void. And in view of the brutal competition that many companies are now
facing, we feel that our product line of stock gears can serve as a
powerful resource for a manufacturer’s competitive posture,” Cervinka
stated.
