The invention concerns a hypocycloidal gear, a method for construction of such a gear and use of such a gear. The method is for constructing a compact gear system with a high gear ratio R, the method comprising, pre-deciding a minimum decided gear ratio R, determining parameters A, B, C, and D with the constraints (C>D and A>B) or (C<D and A<B) such that 1/ä1-Ä(C*B)/(D*A)Üü = R, providing a first gear wheel as a eccentric double satellite gear wheel with a first set of teeth and a second set of teeth, where the number of teeth of the first set of teeth is D and the number of teeth of the second set is B, providing a second hypocycloidal gear wheel with a number C of teeth configured to mesh with the first set of teeth, providing a third hypocycloidal gear wheel with a number A of teeth configured to mesh with the second set of teeth. <IMAGE> <IMAGE> <IMAGE> <IMAGE>
