Spur Gears are widely accepted as the most efficient type of gearing solution, when the application of transmitting power and uniform rotary motion from one parallel shaft to another is required. Determined by the center distance, spur gears create a steady functioning speed drive.

Several of our custom spur gears have been used in gear-train applications – where multiple gears are required to have the same pressure angle and diameter pitch. They are available in plastic, non-metallic, brass, steel and cast iron.

Internal Spur Gears

These internal spurs have a cylindrical pitch surface and teeth which are parallel to the axis. However, the internal gearing teeth are formed on the inner surface of a cylinder. Also, the precision engineered mating component will be an external spur gearing.

When manufacturing ring gears, increased durability is the most important factor to focus on achieving. Ring gearing components, manufactured at AmTech International, allow for very close proximity operation versus externally toothed gears. Also, internal spur gear parts include customized pressure angles to mate with nearly any accompanying gearing type. Our custom ring products are most ideal for light applications, through smooth, quiet operation.

Cluster Gearing Assemblies

Cluster gear types are produced through a precision array or cluster of spur gears, with contrasting bores, on a shaft or gear blank. Normally, these particular gear assemblies are used in OEM automotive, off-highway and marine industry applications.
