Gears

A gear is a rotating machine part that has cut teeth/cogs that mesh with another toothed part in order to transmit torque. Geared devices are used to change the speed, magnitude, and/or direction of a power source, and offer an advantage over pulleys in that they do not slip. When two or more gears work together, they are called a transmission.

Gears appear in a wide variety of types. The principle distinction is between an external gear that contains teeth on the outer surface of its cylinder or cone, and an internal gear that positions teeth on the inner surface. The spur gear is the simplest type, containing a cylinder or disk with teeth projecting radially; others include single- and double-helical, bevel, hypoid, crown, worm, and non-circular.

  • AME Components

    Advanced Machine & Engineering manufactures high precision worm gears consisting of a hollow and a shaftworm. Worm gear blackashes can be changed by turning or moving the hollow worm in relation to the shaftworm. Worm gear teeth have considerably more contact ratio than in standard worm gear pairs. This results in greater power transmission with greater accuracy of the parts.

  • HPC Gears

    HPC Gears manufactures internal gears, helical gears, gear racks and bevel gears for a broad range of applications. Products include a wide bariety of racks in metric and imperial sizes. Spur racks  are available in steel and up to 2 metres in length. stainless steel and delrin racks are produced with Spur and Helical tooth forms, square and round  sections up to 400mm in length. Alternative materials are available on request. Moulded  Hostaform Racks are available to offer an economical alternative where less torque is  required.

  • American Precision Gear

    American Precision Gear manufactures a variety of gears including worm gears, spur gears and helical gears as well as gear racks for a wide range of applications.

  • Garauda Gears

    Garuda Gears manufactures internal gears and helical gears. Garuda internal gears have cylindrical pith surface with teeth parallel to the axis and teeth cut from inside the rim rather than outside. These gears are used along with the pinion. Teeth of internal gears carry the load and are evenly distributed. The center distance of given velocity is short. One thing, which should be kept in mind, is that the difference between teeth of girth gear and pinion gear should not be less than 15.
