Disk 1 whose plane makes an angle not equal to 90° with axis x-x rotates about fixed axis x-x. The turning pair connecting links 1 and 2 is designed as rim a sliding in groove b. Link 2 is connected by a turning pair to link 3 which is designed as a circular slider that moves in fixed circular guide c. When disk 1 rotates about axis x-x, it slides in the groove of annular slotted link 2. Link 2 turns with respect to slider 3 which oscillates about axis y-y. These motions take place under the condition that the axes of all the kinematic pairs intersect at a single point.
