Substantiation of the Need to Create an Eccentric Cycloidal Gearing Transmission of Geokhod

The state of the issue of the underground space development rate in Russia is considered. An analysis of shortcomings of the existing tunneling equipment (tunneling shields and machines) is carried out. It is noted that a promising way of mine tunneling is screw drilling technology, the basic functional element of which is the geokhod. It is claimed that one of the key systems of the geokhod, which determines its efficiency, is transmission. It is noted that the hydraulic cylinder type transmissions implemented in practice at the present time in the form of the development prototype have both their advantages and disadvantages. This does not allow considering the hydraulic cylinder type transmission the optimal solution for its use when designing new-generation geokhod. An overview of various gearing types is made and conclusions about the prospects of using them in the geokhod transmission are drawn. It is claimed that the eccentric cycloidal gearing, according to a set of indicators, is the most suitable for its application in the geokhod transmission. Therefore, studies aimed at proving parameters of the eccentric cycloidal gearing geokhod transmission are relevant.
