The manufacture of automobile gear is a complex, multidisciplinary process that combines materials science, mechanical engineering, precision machining, and quality assurance. Gears are widely used in many applications ranging from simple ones such as wall clocks and wrist watches to complex machines and manufacturing machine tools, automobiles, aviation, defense, very large gear boxes are used in large ships, cranes, wind turbines, railways, aviation, space telescopes to construction machinery, dam gate operations and heavy weight lifting machines and systems requiring positive and phased drives. is. Each gear must meet high standards of strength, durability, and accuracy to ensure reliable vehicle performance over the years of use. With ongoing innovations such as hybrid materials, advanced coatings, and smart manufacturing, the gear making process is evolving to higher efficiency and performance.
