It is also necessary to take into account that a spur gear is cheaper and easier to manufacture than a helical gear.įor the reasons mentioned above, helical gears are often chosen for private vehicles and spur gears for racing vehicles. ![]() In addition, it should be noted that, if we had a spur gear and a helical gear of the same dimensions and similar characteristics, the teeth of the helical gear would have a greater contact area due to their inclination, therefore, its teeth would be more resistant. ![]() The third and final factor is the way the gear teeth come into contact, spur gears do not come into contact “smoothly and gradually” while helical gears do come into contact “smoothly and gradually”, allowing the helical gears to be better to transmit force and speed gradually.The second factor is noise, spur gears at high speeds are much louder than helical gears.Axial load is the most important factor, helical gears produce axial load and spur gears do not.Why choose one or the other? There are generally three salient factors that are taken into account in making this decision: The spur and helical gears are the two most common types of gears. ![]()
