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.

contact and resulting premature gear failure. Also, since the teeth mesh at an angle, a side thrust load is pro-duced along each gear shaft. Thus, thrust bearings must be used to ab-sorb this load so that the gears are held in proper alignment. The three other principle classes of helical gears are: double-helical, her-ringbone, and cross-helical.
