PROBLEMS OF DRIVE MECHANISMS OF TECHNOLOGICAL SECTION OF FIRING AND GRINDING DURING CEMENT PRODUCTION

The analysis of conditions of long operation of driving mechanisms of technological sites of firing and grinding at cement production is carried out in the work. Typical variants of mutual arrangement of crown pair elements in case of rectilinear axis of rotation of technological unit body and axial beating of gear ring, as well as variant of mutual arrangement of crown gear elements in case of curved axis of rotation of rotary unit body are considered. A technique for determining the total angle of skew of the teeth of the crown pair, taking into account the errors of manufacture and the relative position of the wheels of the open gear. On the basis of experimental data the dependences of the total skew angle of the teeth of the crown pair as a function of the rotation angle of the gear crown are constructed and the possible range of the total skew angle under different operating conditions of the considered large rotating units is determined. To assess the stress-strain state of the elements of the ring gear mounted on the furnace body, a solid model was created in the software environment Solid Works Simulation. As an example, the dependences of the change in the magnitude of the deformation of the teeth of the toothed crown in the plane of action of a uniformly distributed normal force are determined. Practical recommendations for improving the design of the crown gear pair are offered. Keywords: rotary kilns; mills; crown gear; toothed crown; the angle of skew of the teeth; finite element method

Simulation of thermal processes in asynchronous traction electric motor of a locomotive

This article analyzes the problem of increasing the reliability of AC traction electric machines installed on traction rolling stock. In the course of the study, a finite element model of thermal processes was built, and the thermal state of an asynchronous traction motor (ATED) of a diesel locomotive was studied in the Solid Works program. The basic method for studying thermal processes in ATED was the finite element method (FEM), as well as the basic equations of heat transfer and the theory of heating a multicomponent solid. The constructed finite element model of the ATED rotor of a diesel locomotive makes it possible to determine the dependence of the temperature values of the rotor elements on the current flowing through them. The obtained values of the temperature distribution of the ATED squirrel-cage rotor are recommended to be taken into account in the design, manufacture and testing of AC electric machines of diesel locomotives.

Comparative analysis on heat transfer of various fin profile using solid works: A systematic review

Fins are widely used to enhance the amount of heat transfer by improving the rate of convection heat transfer. Fins are also known as extended surfaces, i.e., extrusions from the object surface. There are numerous kinds of fins, and based on the shape and size, the amount of heat transfer through the fins will differ. Heat transfer depends upon the geometry of the fin and depends upon a number of factors such as the nature of the fin surface, the ambient temperature; the velocity of the air, etc. In this present study, the systematic review is carried out by critically analyzing the different types of fin profile such as plain rectangular fin, wavy fin, circular pin fin, and rectangular pin fin to increase the fins efficiency. The outcome from this study reveals that the heat transferred by the fins is mainly dependent on the fins profile (type and shape), length, angle, and surface area. Alongside the orientation of the fins, porosity, thermo-geometry also affects the fins’ efficiency.

Dynamic Simulation Analysis and Experiment of Large-caliber Self-propelled Pipeline Crawler Based on ADAMS

The force states of driving wheels are different when the self-propelled pipeline crawler moves in the pipeline, so it is difficult to carry out accurate theoretical analysis and calculation on the force and output torque values of each driving wheel in horizontal, climbing and turning conditions of the crawler. Due to the complex mechanical properties of pipeline sealing and the limitation of visualization, it takes a long period and high cost to develop the robot in pipeline by experimental means. With the gradual application of virtual simulation means, the complicated dynamic analysis and solution process in the past has become relatively easy. In this paper, Solid works is used to establish a simplified model of the crawler, and ADAMS is used to analyze and simulate the dynamics of the crawler. The force of the multi-wheel driven pipeline crawler is given under the condition of horizontal, climbing 35° and turning, which provides the necessary analysis method and theoretical basis for the design optimization and improvement. Finally, the horizontal, climbing and bending motion performance of the crawler is verified by comprehensive pipeline experiment.

Heat transfer analysis on different pin fin types using Solid Works

A fin is an extended part of an object whose purpose is to raise the rate of heat transfer mainly by convection. The heat flow in any object depends on the surface area, temperature difference, and convection coefficient. As convection coefficient cannot vary after a certain limit and temperature difference depends on the process, the way to increase the rate of heat transfer is to increase surface area which was done by adding fins. In this study, steady-state thermal analysis is performed on different types of fins and fins of different heights by using Solid works simulation. Different materials of fins are also used to verify results as the rate of heat transfer is independent of material. Aluminum 6061 and Copper is used as material for rectangular and cylindrical pin fins. In comparison, rectangular pin fin has a high rate of heat transfer as compared to copper pin fin, and also the rate of heat transfer is directly proportional to the height of the fins irrespective of the profile.

Modeling and Finite Element Analysis of Chain Drive using Different Materials

In any automobile the power is transmitted from one shaft to another by using chain drive. Chain drive consists of chain, driving sprocket and driven sprocket. The driving sprocket is connected to engine output shaft, which transfer power to driven sprocket by chain. Further this driven sprocket transfer power to drive shaft. The design and material selection of this chain drive plays a vital role in efficient running of the automobile. Present the material used for chain drive is mild steel. This paper involves increases the strength of the Pulsar 180cc chain drive by selecting the different materials (AISI 1050 steel, EN 8 steel, EN 32 steel, EN 19 steel and C45 steel). In this the Pulsar 180cc chain drive designed through reverse engineering approach and detailed finite element analysis is carried out to calculate stresses and deflections on the chain drive. Later the analysis is extended to fatigue analysis to estimate the life of the chain drive and the dynamic analysis is carried out to calculate stresses and deflections on the chain drive when it is in motion. SOLID WORKS software is used for doing 3D model of chain drive and ANSYS is used for doing finite element analysis.
