“…Moreover, each of those formulas is applicable to a particular class of gears (e.g, hypoid, worm. spiroid, spiral bevel or cylindrical-spur and helical) [15][16][17][18]. More recently, FEM has been introduced to evaluate the contact stress between gear teeth.…”

Additive manufacturing is a technology rapidly expanding on a number of industrial sectors. However, it is still hampered by low productivity, poor quality and uncertainty of final part mechanical properties. Materials for production of given components are composite materials, especially on the basis of so-termed CFRP, CRP (carbon fibre - so-termed polymers reinforced by carbon fibres). Composite fibers have properties that can add high strength and stiffness to the printed part. Like all manufacturing processes, composite printing is only suitable for certain design applications. The fibers have a predetermined width during printing and, due to geometrical limitations, can only be used to reinforce structures meeting a certain minimum thickness. The objective of this paper is to predict the contact stresses of carbon/onyx spur gear using Finite Element Analysis (FEA) results through the torque load. Finite element software ANSYS Workbench 20.0 is used to study the stress intensity factor of spur gear. A 3D solid model has been established for simulation of the spur gear which enables to understand the mechanical strength and strain at failure of the composite materials.

Solving the problem of optimization for transmission load-carrier/prime mover MT-LB improves the mass characteristics of the machine. Mathematical model of optimization was constructed, namely: optimization objective function was built; variables planning are defined; a system of constraints was constructed. The solution is based on probing the parameter space, where points of the LPτ-sequence are used as test points in a single multidimensional cube. Also, the algorithm for optimal design of the transmission has been developed.

The aim of this study is the analysis of the mechanical parameters on the tooth roots having different fillet radiuses in case of helical gears having modified teeth. These gear pairs are widely used in different engineering constructions because of the better load transmission and the more silent noise. Consequently, the development researches are determinable in this field. Designing of one helical gear is needed for the analysis. After that the creation of its CAD model is essential. This gear pair is analyzed by different fillet radiuses on the tooth root of the pinion. All of the other geometric parameters are unchanged. The applied moments are also permanent for each experiment. After the FEM analysis the received results and graph will be evaluated.
