In the present research, the possibility of designing and manufacturing a gear mechanism including a unilobe elliptical gear and a spur gear was investigated. The innovation of this mechanism is the engagement of a circular gear with a non-circular gear and the creation of a continuous movement in one of the two shafts on which the gears are placed. First, the geometry of both gears was assessed and the two-dimensional cross-sectional model of the gears was drawn by Gearotic motion software. Then, 3D models of the gears were produced and assembled, followed by a scrutinization of the engagement of the gears, the proper design of teeth shapes, and the driven shaft movement. The wire electrical discharge machining was employed to manufacture the gears from the Al 7075. Next, the surface roughness of the gear teeth was measured and their engagement checked. The results revealed that the designed mechanism provides cyclic movement in the driven shaft of the spur gear during engagement with the elliptical gear. Moreover, the smooth and proper movement of the gears shows that the use of the software and the correct selection of the input parameters did not cause any errors in the manufacturing process.
