Gear Brass

Gear Brass

Gears are made of variety of materials depending on the requirement of the machine. They are made of plastic, steel, wood, cast iron, aluminum, brass, powdered metal, magnetic alloys and many others. The gear designer and user face a myriad of choices.

A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called cogs), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. call a tooth on a gear The addendum is the height by which a tooth of a gear projects beyond (outside for external, or inside for internal) the standard pitch circle or pitch line; also, the radial distance between the pitch diameter and the outside diameter. Gears can be manufactured by a variety of processes, including casting, forging, extrusion, powder metallurgy, and blanking. Of these, machining is the most common manufacturing method used. Gear machining is further classified into two categories: gear generating and gear form-cutting.
