that the helical gear may be capable of carrying up to fifty per cent more load. Conversely, for a given power, helical gears can be made more compact than a spur set. Helical gears are superior to spur gears in most applications, especially where noise must be kept to a minimum, or the pitch line speed is in excess of 10 m/s.

Helical Gears - an overview | ScienceDirect Topics

Helical gears are similar to spur gears except that their teeth are cut at an angle to the hole (axis) rather than straight and parallel to the hole like the teeth of a spur gear. The line of contact between two teeth is not parallel to the teeth but inclined. This ensures gradual engagement of teeth from one end of tooth to other rather than a sudden engagement as in case of spur gear.
