Philadelphia Gear has built a reputation for quality
and durability by manufacturing high quality precision gearing for
over a century. During these 100-plus years, we've continued to
develop our design and manufacturing capabilities to produce unique,
high capacity gearing solutions for a diverse list of industrial
clients. Please note that Philadelphia Gear is the exclusive provider
of Delaval, Western Gear and WesTech parts.
Our experience has taught us that the higher the level
of precision, the longer a gear system will last. That is why Philadelphia
Gear utilizes the latest in gear production equipment in the manufacture
of our precision gearing. Precision gears are capable of carrying
more load while reducing transient loads. Plus, our precision gearing
runs quieter, lasts longer and ultimately lowers operational costs
by reducing input power requirements. At our Gear Manufacturing
Center in Santa Fe Springs, California, Philadelphia Gear engineers perform
all aspects of gear production, from precision tooth grinding, hobbing,
shaving and lapping, to quality assurance, all in an effort to provide
our customers with the custom gearing they need.
Philadelphia Gear utilizes the following production
methods to manufacture our precision gearing:
• Precision Gear Grinding: The custom-built
gear grinders at Philadelphia Gear are capable of precision
tooth grinding from the smallest pinions to large bull gears
up to 100inches in diameter. Temperature and humidity control
is important in maintaining product uniformity and accuracy
- that's why our tooth grinders are isolated from other
factory operations in air conditioned manufacturing centers.
• Gear Hobbing, Shaving and Lapping: Philadelphia
Gear utilizes ultra precision gear cutters for cutting even
the largest of gears. Surface, finish improvement and tooth
contact optimization are obtained by shaving and lapping
when a particular application requires such techniques.
• Metallurgical Improvement: Philadelphia Gear
has been producing case-hardened gearing for over 40 years.
Philadelphia Gear was the first gear manufacturer to design,
heat-treat and manufacture case-hardened precision tooth
ground gearing in the United States. Today, that metallurgical
experience allows Philadelphia Gear to continue providing
our customers with cost effective gear design solutions.
Further, our solutions include material choice and case
hardening techniques that have become the "best practices"
for the entire industry. And, finally, our case hardened
gears are capable of carrying significantly more load than
conventional gearing. This means that for a given load transmission
task, our gears can be considerably smaller in weight and
size - often significantly reducing inertia loads and lowering
pitch line velocities to more manageable levels.
• Turning and Boring: Philadelphia Gear utilizes
the latest in equipment to meet the turning and boring needs
of any sized gear. For precision gear case boring, we have
available a wide range of technology to fit the needs of
each job, from horizontal boring mills for excessively large
and heavy gear cases, to CNC machine centers for production
of multiple work pieces. Philadelphia Gear also utilizes
a battery of precision surface grinders for absolute flatness
and parallelism of gear housing.
• Gear Metrology and Gear Drive Performance
Assurance: Our Quality Assurance personnel employ sophisticated
checking instruments, ensuring that each manufactured component
measures up to our rigid tolerance specifications. Actual
power transmission equipment operating conditions are duplicated
using various test stands that simulate the same service conditions
our gear drives will experience in field operation.
