From the perspective of manufacturing process and economy, spur gear is a gear with a simple processing process and low manufacturing cost, and its tooth shape is regular, which can be mass-produced using a variety of conventional processing methods.

During manufacturing, through conventional processes such as hobbing and shaping, the gear teeth parallel to the axis are processed on the cylindrical blank, and there is no need to adjust complex helix angle parameters during the processing process, which reduces the risk of machining errors. The cost advantage allows it to achieve basic transmission functions with low investment in scenarios where performance requirements are not extreme.

It is widely used in low-cost mechanical products, such as the transmission system of small blowers, the gearbox of agricultural irrigation pumps, and the drive mechanism of simple conveying equipment.
