Precision Helical Gear
Precision Helical Gear

American Precision Gear Co., Inc. custom manufactures tight tolerance precision helical gears to your specifications. We can produce the most complex helical gear designs, including both left and right hand helixes and single and double helix gears. We work to your specifications and all critical contact surfaces are held to your tolerances (up to 0.0001"). Every ring gear we manufacture is put through our rigorous QA procedures. We can provide our clients with AGMA Level 12 quality gears. Both inch and metric unit helical gears are available.

Helical Gear Specifications

Use
Helical Gears are used to accommodate applications involving high speeds, large power transmission or where noise reduction is important. In addition helical gears allow for additional design flexibility as the rotating shafts do not have to be parallel.
No. of Teeth
Up to 197 teeth
Helix Angle
Typically 45 degrees, but any helix angle is available per your designs
Diameter
Up to 48"
Tolerances
We specialize in holding very tight tolerances on your Helical Gear designs. We can provide up to +/-0.0001"
Quality Control
Conforming to general Military Quality control requirements as follows: MIL-I-45208A, MIL-STD-45662A, ISO 9001:2000 compliant and ISO 13485 Medical Device Certification is pending.
Applications
We provide helical gears to the aerospace, oil and gas, and industrial machining marketplace.
Quantities
As needed.
Lead Time
Average lead time on helical orders is 4 weeks
Preferred Drawing Formats
We prefer to accept CAD files of your designs in DXF format
