Spur Gears Vs Helical Gears - What's the Difference?
Spur gears and helical gearboxes are the most common types of gears. Although their application may be similar, there are several differences between the two. Helical Gears Helical gears work more smoothly and silently as compared to spur gears. In helical gearboxes , the teeth are placed at an angle to the rotational axis. This allows them to have greater tooth strength and higher load-carrying capacity. A major difference between helical and spur gears is that helical gearboxes can transmit power between both parallel and non-parallel shafts. Spur gears, on the other hand, can transfer power only between parallel shafts. Spur Gears Spur gears are the simplest and most common type of gear. They have straight teeth that run parallel to the axis of the gear. Spur gears are the most economical gears as their simple design facilitates easy designing and manufacture. Spur gears can become noisy when used at high speeds. Advantages of Helical Gears Helical gearboxes have...
