Of the mechanical transmissions used in mechanical engineering, the most common are gears with an involute profile of the teeth flanks. Gears made up of such wheels have a number of advantages, but they also have a number of significant disadvantages. Therefore jne of the current trends is the study of gears with a complex non-involute profile of the teeth flank which have advantages over involute gears in a number of applications, as well as the development of tools for their processing. There are two ways of gear teeth cutting: the copying method and the rolling-in method. The rolling-in method has advantages. The profile of the tool working by the rolling-in method does not depend on the number of teeth of the gear being cut, therefore, the same tool can be used to cut gears with any number of teeth. The accuracy of a gear made by the rolling-in method is significantly higher than the accuracy of a gear made by the copying method. This is primarily due to the continuity of the rolling-in process. When cutting teeth by the rolling method, the tooth surface is formed as a result of…

The increase in the complex of operational properties of materials is achieved by performing a combined surface hardening, including the sequential action of various technological methods. The most promising are the technologies of combined modification based on the energy impact of highly concentrated heat sources. At the same time the problem of strengthening of large-sized heavy-loaded products and the tool is especially actual. The influence of the combined induction-plasma hardening of 75X2МФ steel samples on the nature of structural transformations, hardness and fracture toughness was studied. Plasma hardening after induction hardening increases the hardness from HV 780 to HV 930 and the coefficient of dynamic crack resistance from 4,63 MPa ∙ to 9,84 MPa ∙ , which is due to the formation of a surface layer with a highly dispersed structure. An additional factor in increasing crack resistance is the inhibition of cracks at the boundaries of the layers of plasma and induction hardening. An additional increase in the crack resistance of tool steel with combined hardening can be…

The experimental investigations of the intensity of the heat exchange between the internal surface of the thin-wall metal cylinder and the studied liquid medium were carried out in conditions of its cooling (heating), i.e. under nonstationary heat exchange conditions. The existence of the regular thermal mode in the liquid medium surrounded by the thin-wall metal cylinder has been established. Local in time heat loss coefficients were derived using appropriate dimensionless equations for the stationary mode conditions of heat-exchange in a large volume. Heat loss coefficients were determined using regular thermal mode methods and computational-&-experimental heat loss coefficients. The changes in the relative values of the heat loss coefficients were analyzed using the method of regular thermal mode and computational-&-experimental heat loss coefficients. The deviations in the values of given coefficients in time are mainly within ± 10 %. Relative values of the heat loss coefficients deviate within ± 40 % using appropriate dimensionless equations for the conditions of the stationary…

The features of the processes of magnetic-pulse processing of metals in traditional schemes of technological processes of modern industrial production are highlighted. The work is a brief description of the state, application, and also proposed induction pre-heating schemes in industrial magnetic-pulse processing of metals. A method for increasing the efficiency of performing specified production operations is considered. The use of preheating leads to a significant improvement in the quality of production operations while reducing energy consumption. New directions of magnetic-pulse processing of metals are noted, implying the transformation of the natural repulsive forces of the metal of the processed object into the forces of magnetic-pulse attraction with a decrease in the operating frequencies of the acting fields. A significant decrease in operating frequencies makes it possible not only to go from repulsion to attraction, but also to go from working with ferromagnetic metals to non-ferromagnetic ones. For example, it becomes possible to attract aluminum blanks. Examples of…

Research and experimental studies of stress-strain state of discrete-continual hardened machine parts are presented in this work. This hardening method is distinguished by incorporation of numerous hard spots into the surface layer of one of the bodies. Meanwhile the other part is covered by a continuous corundum layer. Correspondingly, a network of microchannels for lubricant is formed between the bodies. Furthermore the contact loads are intensified in the vicinity of the harder material in the discrete zones. As a result the strength and durability of the loaded parts is increased. The technological parameters of the hardening process have great impact on the resulting characteristics. In particular, this concern the shape of the discrete hardening zones and the material properties of the corundum layer. These factors were varied in stress-strain analyses of the contacting bodies. The dependence of the stress-strain state characteristics on the varied parameters was established. The justified recommendations regarding the technological parameters of the discrete-continual…

Before turning the heated air heater (AH) to the blast mode, it is necessary to raise the pressure in it up to the value of the cold blast pressure. This process is called inflation. When the heated AH is inflated, part of the cold blast is taken from the AH, which is being inflated, and fed into the heated one. Thus, for a certain time there is a branching of the cold blast flow – the main flow goes to the AH of the hot blast, and part of it goes to the hot blast. As this takes place, the hydraulic resistance of the cold blast supply pipeline system decreases and during this period the pressure in the cold blast pipeline drops sharply, which is evidenced by the decrease in the mass quantity of blast to the furnace. To estimate the amount of the blast losses (BL) during inflation, the AH is considered as a closed tank, at the inlet of which cold blast is supplied with a certain pressure P1 in the pipeline in front of the AH unit and, in the working space of which, there will be pressure P2. During the inflation, P2(τ) begins to change from atmospheric pressure to cold blast…

The article is devoted to the actual problem of increasing the performance indicators of machine gear drives. To solve this problem, in the article proposed to use a conchoidal engagement made with a shifting of the reference profile and special contact conditions. A feature of the proposed engagement is that it is less sensitive to manufacturing and assembly errors compared to conventional conchoidal engagement. As a result of theoretical studies, the performance indicators of such an engagement were determined. This made it possible to determine the level of load during further experimental tests of new gears. Contact strength and meshing losses were selected as performance indicators subject to further experimental verification. The ratios of these indicators, calculated for conchoidal spur gears with convex-convex contact, made with a shifting of the reference profile, with similar involute ones, are theoretically determined. Comparative analysis of performance indicators was carried out for gears of involute and conchoidal engagement with the same parameters and shifting of the…

The results of investigation of the conditions for obtaining macroheterogeneous chemical compositions within the limits of the single bead by submerged-arc surfacing with composite strip electrode are presented. Studies included the numerical calculations and simulation of heat distribution based on solution of nonlinear differential equation of heat conductivity. Temperature-dependent base metal properties were considered when calculating. It is shown that the mathematical modeling of the process of heating and heat propagation in a semi-infinite body during wide layer surfacing makes it possible to evaluate the influence of the geometry of composite strip electrode on the formation of the weld pool. The shape and dimensions of the pool is affected by the transferred flow of the molten metal. With the increase of the gap between the central and lateral strips of composite electrode the intensity of the transferred flow weakens because of the decrease in the conditions, especially in reducing the fluidity of liquid metal in certain parts of the weld pool. The data of computational…
