“…1) [8,9,10]. At present, a prototype of Geohod with working body for destructing rocks of medium strength has been created ( Figure 2) [11,12,13,14. Therefore, the works aimed at developing technical solutions for the location of cutting elements relative to the center of rotation of Geohod for destructing rocks with a strength up to 1 of Protodyakonov hardness are topical.…”

The article presents the technical solution for the location of cutting elements relative to the rotation center of Geohod for destructing rocks with a strength up to 1 of Protodyakonov hardness. The relevancy of the research is considered. General information about Geohod is given. The features of working body of Geohod are described, in particular, the formation of a complex shape of the face and the working body, and it is also said that in the case of screw movement of working body of Geohod to the face, the points of working body form a helicoidal (helical) surface. To set the purpose and objectives of the study the geometric parameters of generatrix are justified. The parameter depending on the number of blades and on the radius of location of the blade’s cut is identified. Based on the study, the dependence of the number of blades on their location from the center to the periphery is determined. The design of blade working body of Geohod for rocks with a strength f <1 of Protodyakonov hardness is offered. Also the directions for further research have been identified, which include: the development of methods for calculating cutting forces for a technical solution for the location of cutting elements relative to the center of rotation of Geohod for destructing rocks up to 1 of Protodyakonov hardness; the application of this technique for obtaining variants of the blade working body of Geohod of different types.

“…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].…”

“…We have suggested a mathematical model to calculate a turning moment made by transmission according to accepted dimensions of geokhod, necessary clearance of internal space, and conditions of mine working [2,3]. It is stated in paper that the moment made by transmission tooled with hydraulic cylinders will change periodically because of alternating lever of force exertion by hydraulic cylinders.…”

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.

“…So power crowding are created as a result of introduction of elements of the propulsor to the peripheric massif and uses of the normal reaction arising at interaction of elements of the propulsor of the geokhod with the massif of rocks. At present, a prototype of geokhod is manufactured with the cutting body for destruction of rocks of medium hardness ( Figure 1) [8,9,10,11]. At the existing development stage of elements of geokhod technology is particularly acute need in development of constructive and technical solutions of working body which is capable to carry out formation of a cavity in underground space on grounds with a hardness up to 1 on M.M.…”

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.
