Abstract	Design and development of involute spur gears are played a vital role in mechanical engineering, especially for use in car transmissions. The current work involves the design and development of a spur gear for a 110-cc engine used in two-wheelers. The design process includes the calculation of important parameters like module, number of teeth, pressure angle, and selection of material to ensure that the gear can resist the torque and power of the engine. The gear is designed with a module of 3, teeth of 27, and a pressure angle of 200. Strength calculations involving bending stress and contact stress are computed to check the durability of the gear under working loads. The gear is manufactured with the use of cast iron, and the process involves gear cutting, and finishing methods. The finished gear is checked for correct meshing, and bearing capacity. The outcome proves that the designed spur gear satisfies the specified strength and performance requirements, which in turn ensures efficient functioning in the 110-cc engine. The manufacturing processes for spur gear production were studied in the current work.
