“…Determining the coefficient of tooth friction is not simple, as it is influenced by the properties of the lubricant, the lubrication method, the material and design of the gears, the surface condition, surface roughness, operating conditions, load, speed, and temperature. The power loss due to tooth friction can be described by relation (9) (see [24]).…”

In this paper, a software framework is presented through an application that is able to jointly optimize an electric motor and a gearbox for the design of a drive system for electric vehicles. The framework employs a global optimization method and uses both analytical and finite element method (FEM) models to evaluate the objective functions. The optimization process is supported by a statistical surrogate model, which allows a large reduction of runtime. An earlier version of this framework was only suitable for electric motor optimization. In the application presented in a previous paper, the motor of a belt-driven electric drive system was optimized. In this paper, the optimization of the same drive system is shown, but now with a combined optimization of a gear drive and motor. The objective functions of optimization are minimizing the total loss energy and the weight of the drive system. The optimization results are compared with previous results to demonstrate the further potential of joint optimization.

“…The design and geometry of gearboxes play a key role in their energy efficiency, and the microgeometry of gearboxes not only affects energy loss, but is also a determinant of noise emissions (see [9]). In this case, we focus on energy and mass optimization, as these factors directly affect the efficiency of the drive system operation.…”

“…In particular, we focus on mechanical transmissions, which are widespread systems in industry, from vehicles to renewable energy, and from machine tools to automation and robotics [30][31][32][33]. Many studies focus on transmission machines from multiple perspectives, such as manufacturing and finishing [34][35][36][37][38], or metrology and tolerances [30,[39][40][41], but only a few of them deal with their design knowledge management. The studied subsystems for mechanical transmissions are both designed and manufactured by a leader multinational corporation and are definitely defined mature products with stable technologies.…”

The Systematic Design of Industrial Products through Design Archetypes: An Application on Mechanical Transmissions

Engineering design is a knowledge intensive activity for both new and mature technical systems, such as mechanical transmissions. However, design knowledge is often transferred with conservative and unstructured approaches, although knowledge management would be of the utmost importance for modern industries. In this work, we introduce a design tool, called design archetype, for collecting and managing knowledge in systematic design processes. The design archetype addresses input design requirements for different design concepts, therefore, improving awareness of the design process by interactively modifying the design solution due to different input requirements. Finally, the design archetype updates the parameters of a first embodiment computer-aided design model of the concept. A method for the development of design archetypes is presented and applied to two case studies of mechanical transmission subassemblies. The results demonstrate the effectiveness of a systematic design method based on design archetypes stored in the company database.

Many modern technological processes are implemented at high speeds of the machine tool operating bodies relative to the workpieces. With significant dimensions of the processed parts, rack-and-gear drives are used. The design features of the rack-and-gear drive require coordination of the servo drive with the machine operating bodies movement speeds using a gearbox. This paper considers the possibility of creating a gear-belt gearbox for drives of highspeed equipment. The applied gearbox should not cause additional errors in the movement process. The work carried out experimental investigations of a servomotor dynamic characteristics and the qualitative characteristics of measuring encoders, the gearbox influence on the displacement error, machine tool axis movement. The dynamic characteristics of a servomotor without load, assembled with a gearbox and as part of a controlled axis of a portal-type machine have been investigated. It is determined that the delay time of the movement start is no more than 0.002 s for a servomotor without load and as part of a gearbox, and the delay time of the movement start of the gearbox output shaft does not exceed 0.003 s. It has been determined that the maximum possible acceleration of the controlled bodies of the machine during using the considered drive is 8 m/s 2 . The dynamic error of the axis movement along a straight trajectory does not exceed 0.023 mm, and along a circular trajectory -0.035 mm. The error of position determining for the operating body is no more than ±1 discrete. This indicates that the gearbox error is less than the error of the position measurement system used in the investigated machine.
