Gears can be classified according to six criteria namely (1) according to configuration: external and internal gears; (2) according to axes of transmission: (a) for transmission between parallel shafts: straight toothed spur gear, single helical, and double helical or Herringbone gears, (b) for transmission between intersecting shafts: bevel gears (straight-tooth, spiral-tooth, zero-bevel, crown, and mitre type), (c) for transmission between non-parallel and nonintersecting shafts: spiral gears, hypoid gears, worm and worm wheel; (3) according to pattern of rotation: (a) rotation to rotation, (b) rotation to translation and vice-versa (i.e.
Corona spiral gears, DC motors, control panels, door locks and regulators are all made locally according to old designs, says Abdel Atta.
The two primary types are spur or straight-cut gears and helical or spiral gears. Herringbone types have been produced in the past but will not be discussed here.
