Calculation of the dimensions in a gear system: pinion and gear, determines the parameters according to the number of teeth, pressure angle and diametral pitch:
- circular pitch,
- distance between centers,
- pitch diameters,
- base circles,
- New pressure angle on slightly spaced mated gears,
- Pressure line length,
- contact ratio,
- Indicates if there is interference
- Lewis form factor.

Animation of the system to analyze the contact relationship and validate if there is interference.

Use for design and manufacture of transmissions or mechanism of gears or spur gears coupled to motors.

* Use of Spur Gears:
- Power Transmission: They are used to transfer energy between mechanical components.
- Change of Direction of Motion: Allows the direction of rotational motion to be modified in aligned systems.
- Speed Reduction: They are used in gearboxes to reduce rotational speed while increasing torque.

* Manufacturing of Spur Gears:
- Design: A detailed design is made using CAD software, considering factors such as material, size and load.
- Materials: They are commonly made of steel, stainless steel or high-strength plastics.
=> Manufacturing Processes:
- Machining: Techniques such as milling, turning and grinding are used to shape the teeth.
- Heat Treatment: Heat treatments are often used to increase their hardness and strength.
- Finishing: Finishing processes are performed to improve accuracy and minimize wear.

Spur gears are fundamental in mechanical engineering and are found in a wide variety of applications, from household appliances to industrial machinery.
