Tsiriggakis' Gearless Differential 
Mr. Tsiriggakis Differential is at the disposal of all scientists all over the world. Take into a serious consideration the fact that many other mechanisms can be constructed based on this kinematical theory, depending on the inventiveness of the scientists that will conduct research on this technology. This means that new horizons in the field of transmission of motion will be opened. Examples of mechanisms that can be constructed using Mr. Tsiriggakis' kinematical theory are revolutions reducers, gearboxes and others.
It is remarkable the fact that Mr. Theodore Tsiriggakis' has personally tested his Differential by applying it on cars. These cars have covered tens of thousand kilometers, driving a car with such a Differential gives an amazing feeling of safety and reliability.
The Differential that we present in this Web Page is the first piece that Mr. Theodore Tsiriggakis has constructed in 1981 in his laboratory. He has constructed the differential based on the design that we present in order to register the patents and his kinematical theory. In case of a production Mr. Theodore Tsiriggakis claims that alternate designs must be used depending on the type of the vehicle.
1. The vehicle follows a straight track
The following animations show the motion of the planets and satellites when the vehicle follows a straight track, there is no differentiation. Bear in mind the fact that the satellites can be either rolling objects or sliding objects. By clicking on each of the following animations a more enlightening animation will appear.

2. The vehicle takes a right turning
The following animations show the motion of the planets and satellites when the vehicle takes a right turning, there is a partial differentiation. Bear in mind the fact that the satellites can be either rolling objects or sliding objects. By clicking on each of the following animations a more instructive animation will appear.
3. Complete Differentiation
The following animations show the motion of the planets and satellites when the one motive wheel rotates clockwise, the other motive wheel rotates anticlockwise with the same angular velocity, there is a complete differentiation. Bear in mind the fact that the satellites can be either rolling objects or sliding objects. By clicking on each of the following animations a more informative animation will appear.
