Gear Engineering Solutions

ASI Drives has a broad and deep knowledge of gear technologies. We can help solve an existing problem or design a system from the ground up. We have decades of experience, with a wide variety of gear drive system applications. We utilize three specialized gear systems, combined with conventional gearing expertise, for a complete selection of the best gear arrangement to use. We have well-developed global sources of supply which result in high-quality components at the lowest possible 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
  • Mesh efficiencies generally 95+%
Evoloid® 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 of involute system
  • Manufacturing processes and sequencing is generally the same as those for involute gearing
Convoloid® Gearing

Angled Axis (AA) Gearing:

  • A performance enhancing and more cost-effective approach to applications that typically require spiral bevel technology
  • Axis angles from 0° to 135°
  • Mesh efficiencies of +95%
  • Patented design permits cutting or grinding of face gear on traditional machinery
  • Combined with Evoloid® pinions, high single pass ratios are achievable, i.e., 7:1 to 22:1
Angled Axis Gearing

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
