Free Standing Teeth (FST) Gear Reducer, is a new single stage gear system that reduces input speed by great gear ratio and provides high torque amounts. In this system the direction of output rotation can be obtained either to the direction of input rotating or the counter direction of it. This gear system consists of one or more eccentric element (7) which is similar either sliding contact element (e.g. cam) or rolling contact (e.g. roller) element, free standing teeth (8) which are drived by these eccentric elements (7) and mate gear (9) which is being internal or external. That is to say free standing teeth work either as an internal or as an external gear's teeth. In summary this system is a rijid body gear system but has also free movable parts that is, different from both conventionnal rigid body gear systems and elastokinesis gear systems.
