Abstract
The main feature of the proposed work is a comparative analysis of the use of a gear landing with guaranteed tension on hollow and solid-section shafts. In order to reduce the stress concentration and increase the malleability of the joint, it is also proposed to reduce the thickness of the hub. The conclusions of the research in the form of calculated data confirm the effectiveness of the proposed measures. As a result of these structural changes, the cross-section of the joint becomes smaller: for the structure under study compared to the basic assembly, i. e. with a wheel with a conventional hub and a solid-section shaft, 1.7 times. Consequently, the metal consumption of the unit decreases, the loads on the shaft supports and the drive decrease, and the energy efficiency of the device increases.
