In this bending calculation, the driven shaft of a gearbox with a gear is used. The hub of a wheel pressed onto a shaft can serve as a bushing, increasing the cross-section of the shaft. When choosing a fit for the wheel hub on the shaft, it is important to exclude rotation of the wheel on the shaft, as well as the possibility of the joint opening due to a bending moment. According to the results of the analysis, the strength of the annular shaft under the hub of the pressed wheel turned out to be quite high. Calculations have showed that the strength reserves of a hollow shaft with a pressed wheel hub for bending increase from 2.1 to 4.39, and for deflection deformation from 3.85 to 4.5. The calculation shows savings in material consumption for the manufacture of the driven shaft of the gearbox compared to a solid section. At the same time, the load from its own weight on all structural elements is reduced, and the manufacturability of the shaft is increased, since they are designed smooth, and the same range of parts is used as for a solid section shaft
