Increasing the Efficiency of Drilling Rigs by Using the Blagonravov IVT in the Top Drive System

The article deals with the issue of installing a mechanical infinitely variable transmission with an electric drive in the top drive system of drilling rigs. The disadvantages and advantages of the top drives existing design of drilling rigs in electric and hydraulic versions are considered. The results of the external characteristics calculation of the top drive are presented, showing that the use of Blagonravov mechanical infinitely variable transmission as a reduction unit will provide a more complete use of the electric motor power. At the same time, the dimensions of the transmission will not exceed the dimensions of the existing top drives of the corresponding power.
