helical Gears MAKE A DIFFERENCE YOUCANHEAR Helical Gears vs Spur Gears Helical gears have slanted teeth compared to spur gears with straight eut teeth, producing a smoother gear mesh, resulting in a significant reduction in noise levels. ■ Smooth, quiet operation ■ Input speeds up to 6,000 rpm Typical sound level diffrence between spur gearing (left) and helical eut gearing. The db(A) scale is logarlthmic. An increase of 3db doubles the apparent volume.
