IKONA'S Technologies

Unique Design

Ikona possesses a unique patented gear design technology which enables extremely high gear ratios to be achieved in a single stage of gearing, which can be used to create high-ratio gear reducers or gear increasers. Ikona has an expert gear engineering team and the knowledge and experience to custom design engineering applications for virtually any of your needs.

Intelectual Property

The heart of the patented Ikona intellectual property is a non-involute tooth form based on a design created in Dnepropetrovsk, Ukraine, a military technology enclave of the former USSR, where the gear technology was designed to reduce the weight of gearboxes in military attack helicopters. Ikona acquired this technology and further developed it, and patented it in the USA, Canada and Europe.

Designed stronger & lighter

Ikona is the only practical gearing technology that has achieved a difference of one tooth between the internal and external gear. As a result, the Ikona gear is capable of much higher gear ratios, much higher meshing and gear contact ratios, than competing involute technology. This means that in high ratio applications, the Ikona gear can be designed stronger, lighter and with fewer parts (lower cost) than normal involute technology.

Revelutionary one tooth difference method

Illustration #3 on right demonstrates how Ikona can achieve a 44:1 gear ratio by combining a 44 and 43 set of external and internal gears (one tooth difference). Involute technology would require a 5 tooth difference to prevent tip interference, and as a result of a 44 and 39 set of external and internal gears, the result would be an 8.8:1 gear ratio, with inferior meshing and much lower contact ratio.

Also, the non-involute design and patented tooth form results in the internal teeth being wedged into place at 10:00 and 2:00 o'clock on the outsides of their teeth. This results in theoretically zero back-lash which is highly desirable in positioning drives such as in robotical applications.
