Bronte Precision talks Internal Gears in latest capabilities blog

An Internal spur gear is a gear with its teeth cut in the internal surface of a cylinder and meshes with spur gears.
Bronte Precision can also engineer Internal Helical Gears.

Spur gears are one of the most extensively used types of parallel-shaft gears as they have high mechanical efficiency. Due to the noise and vibration of simultaneous contact between the teeth which continuously shock loads across the entire tooth face, spur gears are mostly suitable for low to medium speed applications.

Internal gears are often used in applications involving planetary gear drives and gear couplings. There are three major types of planetary gear mechanisms: planetary, solar and star types. Depending on the type and the pattern of which shafts act as input and output, many variations of speed transmission ratios and rotational directions are produced.


Bronte Precision have an extensive portfolio of gear production capabilities which includes the ability to produce all of the individual gears that make up a Planetary Gear System and full Gearboxes. For specific manufacturing capabilities such as minimum and maximum diameter and face width see our Gear Cutting page and please get in touch in you require any further information.


We also have decades of experience when it comes to gear engineering and design. We will work with you through the entire process to ensure your gears are designed and manufactured with precision. Our engineering services also include reverse engineering of gears.
