The wind turbine engineer must have enough knowledge to specify the application, environ-ment, loads, gear life and quality, acceptance criteria, noise, and many other factors, and relate this information to the gearbox vendor. Still not sure the best type of gear to use for your next project? Ask the experts! involvement of the wind turbine engineer during the design and procurement process. So there you have it, those are the main differences between helical gears and spur gears. A downside to helical gears is they produce an axial thrust that needs to be accounted for something not needed with spur gears. Further, helical gears can transmit power between either parallel or non-parallel shafts, while spur gears can only transfer power between parallel shafts. Helical gears also have greater tooth strength and a higher load carrying capacity.

Since the teeth engage more gradually, they have a smoother and quieter operation than spur gears. Title: Computer Aided Optimal Design of Helical Gears. Thesis, the University of Texas at Arlington,2010 Keywords Design, Modeling, Helical Gear, Bending Stress, AGMA, FEA. Helical Gears have teeth that are set on an angle to the gear axis. Muthukrishnan for the Master of Science in Mechanical Engineering presented December. Shreyash D Patel, Finite Element Analysis of Stresses in involute Spur Helical gear, M.Sc. They run well at slow to moderate speeds, but they tend to vibrate and become noisy at higher speeds. Spur gears are not known to be the smoothest or quietest gears, but they are highly efficient and produce a lot of power. Since they have the simplest design, they are the easiest to design and manufacture, and are therefore the most economical type of gear. They have straight teeth that are produced parallel to the axis of the gear. Spur gears are the most common type of gear, and are also the most simple.

They can often be used for the same types of applications so what are the differences between helical gears vs. Spur gears and helical gears are two of the most common types of gears.
