“…It agrees developing technical solutions, on the basis of a structural portrait of the geokhod, beams of WB can be at an some angle to pivot of the geokhod. The corner y (figure 1) can be: equal 90 angle degree, less than 90 angle degree -WB takes a form of a right cone, more than 90 angle degree -WB will be in the form of the back taper [7].…”

Abstract. Influence of geometrical parameters of generatrix of helicoid on a guide of geokhod bar working body is proved in article. The relevance of the conducted research is considered and proved. General characteristics of the geokhod are presented. Features of geokhod working body, in particular formation of irregular shape of a surface of a face and working body are formulated and also it is told that at screw movement of geokhod working body of a face, points of working body will be formed a helicoid (screw) surface of a face. For establishing of the goals and objectives of research general geometrical parameters of generatrix is marked and justified which treat length of generatrix, width of generatrix of helicoid, pitch of helicoid and it's form. Forms of guides of geokhod bar working body based on basis parameters of geokhod and accepted general geometrical parameters of geokhod working body are received and presented. In virtue of the conducted research the dependence of a form of a guide of bar on general geometrical parameters of helicoid is defined and also basis parameters of helicoid in influencing a form of guide of working body.

“…A basic feature of the geokhod is the screwing into the contour strata of the body which performs the function of the mobile support. At the same time, the force providing motion and balancing the reaction from the technological operations is formed not by friction forces at the media interface (soil-crawler mechanism) or repulsion from an artificially constructed support element (hydraulic jack-permanent support), but as a result of introducing the propulsion elements in the contour strata and the use of a normal reaction arising from the interaction of the elements of the geokhod with the rock mass [5][6][7][8].…”

Abstract. The article presents the power dependencies for determining the number of blades of the cutting body of geokhod for destruction of rocks of low hardness. The obtained dependences are based on the developed method of calculation of the blade cutting body of the geokhod. The presented dependences make it possible to choose the rational number of blades of the geokhod cutting body. The intensity of the development of underground space by the countries of the world community, including Russia, is increasing. In this connection, the tasks are to increase the rate of development and to reduce the cost of work.

“…Conventional drives with mechanic transmission and electric or hydraulic motors are difficult to utilize because of insufficient mass-overall parameters [1][2][3][4][5][6][7][8][9]. It is also a problem to use rather perspective wave gears with interposing rolling elements because of their technical complexity and technological imperfection [10,11].…”

Abstract. The issue of designing drives, which provide low frequency (max. 1 rotation per minute) rotation with a big moment (min 1 MN m) of large technical bodies utilized in restricted spaces, is a complex and contradictory one. The drives of geokhod propeller, rotor actuators of tunneling machines with overload protection, as well as actuators of other machinery meeting aforementioned requirements are examples of such machines. The paper considers mathematical model developed by the authors which determines the relation of design factors of transmission tooled with hydraulic cylinders to kinematic parameters of output element movement. The paper also provides description of methods to determine pumping unit efficiency for rotary transmission tooled with hydraulic cylinders.
