- A broad and deep knowledge of gear technologies to help solve an existing problem, or design a system from the ground up.
- Decades of experience with a wide variety of gear drive system applications.
- Three
specialized gear systems, combined with conventional gearing expertise
for a complete selection of the best gear arrangement to use. (For
details, see Gear Design Technologies.)
- Well-developed, global sources of supply result in high quality components at lowest cost.
GEAR DESIGN TECHNOLOGIES

|
 |
Evoloid® Gearing:
- Provides excellent efficiency and high power density.
- 3, 4, 5 tooth parallel axis helical pinions, no undercut, no pointed teeth.
- Single pass ratios from 7:1 to 22:1.
- Computerized stress analysis.
- Customer's special requirements.
- Mesh efficiencies generally 95+%
- Plastics to hardened gearing.

Convoloid® Gearing:
- New, patented, non-involute tooth form.
- Significant improvements in surface durability compared to involute forms.
- Increase rated power of existing gear system in same housing, or
- Reduce size of present gear drive system for same performance as involute system.
- Manufacturing processes and sequencing is generally the same as those for involute gearing.
|
|
|
|
 |
Angled Axis (AA) Gearing:
- A
performance enhancing and more cost effective approach to applications
that typically require Spirod®, Helicon®, or spiral bevel technology.
- Axis angles from 0o to 135o.
- Pinion offsets permitted.
- Mesh efficiencies of +95%.
- Patented design permits cutting or grinding of face gear on traditional machinery.
- Plastics and powdered metal technology can be utilized.
- Combining with Evoloid® pinions high single pass ratios achievable, i.e., 7:1 to 22:1.

Conventional Gearing:
- We use computerized stress analysis standards of the American Gear Manufacturers Association.
- We can analyze bearings, shafts, and other interfacing components.
- We can match ratios, center distances, and other special requirements.
