In spur gears, the engagement of teeth of driving and driving gear is sudden, when it is working. This is because of the different engagement of helical gear teeth compared with spur gears. The most important advantage of helical gears is the smooth operation compared with spur gears. What Are The Advantages And Disadvantages Of Helical Gears? With this type of assembly, the shafts attached to these helical gear pairs will be parallel, which is the desired construction. In helical gear pairs, one of the used gear must be left hand and another one must be the right hand to obtain flat and even construction. According to this orientation, helical gears are called left-hand helical gears and right-hand helical gears. This angle can be leaned to both the left side and right side in helical gears.

Machine Elements in Mechanical Design (What’s New in Trades & Technology) The angle between the orientation of teeth and the axis of gear is called as helix angle. If this angle is 0, this type of gear is called spur gear. But if there is an angle between the teeth orientation and axis of the gear, these types of gears are called helical gears. The main difference between the spur gear and helical gear is the orientation angle of gear teeth according to the axis of the gear.
