Gears, Racks and Worm Wheels


Anti-Backlash Gears

Anti-Backlash Gear
Nordex’ Anti-Backlash Gears are available in two designs – Interchangeable and Compact. Anti Backlash Gears are available in 24 Pitch to 120 Pitch in stainless steel and aluminum, pin hub and split hub. Nordex also offers Anti-Backlash Miter Gear Sets. Please consult Nordex’ customer service department for unlisted sizes. Custom machining available on request.

Miter and Bevel Gears

Miter and Bevel Gear SetNordex offers Miter and Bevel Gears with a 20 degree pressure angle AMGA quality 10 gears. To order AMGA quality 12 gears, please contact Nordex directly for pricing per set.

Broken Sets
Individual miter and bevel gears from matched sets can be ordered separately. It is important to specify which set the single gear is to fit.

Helical Gears

Parallel Shaft Helical Gears

Parallel shaft application of helical gears result in smoother action than spur gears because, the load is transferred uniformly and gradually as successive teeth come into play. They also reduce noise and vibration.

To substitute normal pitch helical gears for spur gears while Helical Gear substitution for spur gearsmaintaining center distances and ratio, proceed as follows: Select a diametral pitch finer than the spur gearing employed (called the new pitch) and divide the spur gear diametral pitch by the new pitch. This results in the cosine of the helix angle required.

Therefore the helix angle = 27 degrees 16 minutes and the diametral pitch in the plane of rotation remains 64. One would therefore employ a helical gear cut with a standard spur gear 72 pitch hob set to cut a helix angle of 27 degrees 16 minutes.
