What is hobbed gears?

Hobbed gears are used in many mechanical systems to transmit power and motion. They are cylindrical gears that are cut using a special tool called a hob. The hob is a cutting tool that has teeth that are shaped like the desired teeth of the gear. As the hob rotates, it cuts into the gear material and forms the teeth.

Hobbed gears are used in many applications, including automotive transmissions, robotics, and industrial machinery. They are also used in hobbyist projects such as 3D printers and CNC machines.

One of the advantages of hobbed gears is their efficiency. Because the teeth are precisely cut, they engage with each other more efficiently than gears that are not hobbed. This means that less power is lost due to friction, resulting in higher efficiency and smoother operation.

Hobbed gears can be made from a variety of materials, including steel, brass, and plastic. The material used depends on the specific application and the desired properties of the gear. For example, steel gears are often used in heavy-duty applications where durability is important, while plastic gears are used in applications where low weight and corrosion resistance are required.
