The possibility of using spiral-screw conveyors in smart-transport systems of municipal services has been studied in order to reduce traffic congestion caused by the destruction of the roadway or seasonal precipitation (winter sediments), which reduce the efficiency of the road transport infrastructure and increase the level of environmental pollution. Internet technologies make it possible to obtain information from all available sources: traffic lights, cameras and sensors, analyze this data and use the information for a prompt response to emergency situations. For efficient operation of spiral-screw conveyors of a smart vehicle, it is necessary to select a control link based on computer modeling, consisting of a motion source and a motion transducer interacting with an actuator to coordinate the parameters of their operation. A technique for determining some of the most important characteristics of a conveyor is presented, on the basis of which, depending on the Reynolds number, variants of its application are recommended. When choosing a motion converter, depending on the required performance and characteristics of the transported medium in CAD/CAE systems, the calculation and design of bevel gearboxes for the spiral-screw conveyor of mobile machines and plants infrastructure of the “smart city”. In the process, a three-dimensional bevel gear was formed using CAD tools and calculated for strength. The main dimensions of the gears, the power and strength parameters of the bevel gearing, shafts and bearings were calculated in the APМ TRANS, APМ SHAFT and APМ DEAR modules of the APМ WinMachine system. In addition, the calculation results can be used to select a standard gearbox.
