1) Description of Helical gears
Helical gears contain special teeth that are placed at a particular angle to the shaft.
This leads to more than one tooth being in touch during the function, making the gear capable of tolerating more load.
This configuration also allows helical gears to perform quieter and smoother than spur gears because of the load sharing between teeth.
