1) Features of Helical Gears
Helical gears are often the default choice in applications that are suitable for spur gears but have
non-parallel shafts. They are also used in applications that require high speeds or high loading.
Regardless of the load or speed, they generally provide smoother, quieter operation than spur gears.
Besides smoother motion, higher speed capability, and less noise, another advantage that helical gears
provide over spur gears is the ability to be used with either parallel or non-parallel (crossed) shafts.
Helical gears with parallel shafts require the same helix angle, but opposite hands (i.e. right-handed teeth vs. left-handed teeth).
