The principle of internal gear complex and external gear is completely consistent (involute, gear principle). It is just that the tooth groove of the inner gear is equivalent to the tooth of the outer gear. For example, the top cutting system of the inner gear of the liugong loader accessories is equivalent to the root cutting of the outer gear. In the design, calculation of the internal gear parameters, the tooth groove as the tooth of the external gear can be, but always pay attention to you are in the calculation of the internal gear, some tooth thickness, the size of the width of the tooth groove do not get the opposite.
