Also called the dry fixed gears, helical gears are regarded as the refined version of spur gears. Though they are also cylindrical, their teeth are not made parallel to their rotation axis. Rather, they are angled and look like a segment of a helix, hence their name. With their tooth configuration, they run smoother and quieter than other types of gears and can support heavier loads efficiently. They are also designed in a manner that pressure is distributed gradually along with its entire tooth.
With the application of pressure, helical gears are subject to axial thrust. But this can be easily addressed by applying thrust bearings and special lubricants. They come in two teeth configurations: right hand and left hand. They can transfer energy through two axial configurations as well, perpendicular or parallel axes with the use of their helical teeth. The perpendicular-axis gears, otherwise known as skew gears, transmit energy through a 90° angle. Conversely, parallel axis helical gears come in two opposite hands to offer high load capacity and quiet operation.
In addition, helical gears are utilized in many applications that need heavy load efficiency and silent operations like in the automobile industry. They are also the most preferred choice in many other manufacturing sectors like printing, fertilizers, earthmoving, steelmaking, as well as food industries. They are found to be very useful in the use of elevators, conveyors, compressors, and other industrial equipment and machines.
