The invention relates to a transmission which is always unbalanced, and the torque resulting from the imbalance can be used to generate energy. A rotating system which is always unbalanced is characterised in that the amount of right-rotation torque must be constantly differentiated from the amount of left-rotation torque. The perpetual motion machine of the invention designed to solve this problem is based on a special embodiment of a cross-sliding mechanism that replaces the Cardan circle pair, together with an intermediary. There are two variants, and according to the special embodiment, the bearings of the corresponding variants of the corresponding Cardan wheel are not fixed bearings but floating bearings. In the operating position, the axes of rotation of the Cardan wheels are on the same preferably horizontal level. The weight force components, the floating bearings and parts connected thereto are supported by Cardan wheel thrust guiding elements and guidance, and Cardan wheels comprising fixed bearings are subjected to such torque. The intermediary receives torque in the first step, which is then transferred, in the second step, to another Cardan wheel. The system is rotated in an accelerated manner out of the stationary position.
