摘要：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.
