Helical gears are ideally suited for very high speed and take up appreciable load. Helical gears primarily join to parallel shafts, with the teeth lying along helices. Parallel shafting ensures high speed and application where spurs gears are used. Helical gears are widely recommended for all high speed and high load meshes. Helical gear is more or less equal in quality to spurs except the complication of the angle. Proper lubrication should always be done in use of helical gears.
