A standard spur gear has straight teeth that are parallel to the gear’s axial axis. On the other hand, the helical gear, as the name suggests, has teeth that are inclined to a certain degree. Such a design allows a larger contact ratio for the gears and is, therefore, able to transmit greater forces. It also decreases the shock and wear by gradual contact. It is applicable for both parallel and crossed shafts. The other advantage is the quietness during operation. The use of gears with a helical design is prevalent in industries such as automotive, power tools, engineering, and more.

Powder metallurgy allows for mass production of Helical spur gears with precise tolerances. This ensures the consistent quality of gears even in large quantities.
Gears produced through powder metallurgy exhibit excellent impact resistance. This is vital for helical gears, which often transmit significant forces in various applications.
