Predstavljeno doktorsko delo zajema poglobljeno raziskavo o termo-mehanskem obnašanju polimernih valjastih zobnikov med obratovanjem, na podlagi katerih je bil razvit napovedni model za določitev temperaturnih prirastkov v strukturi polimernih zobnikov, kot posledica obratovalnih izgub. Omenjeno pov ...

The engineering characteristics of polymer gears, such as wear and fatigue resistance, are dictated by the underlying processes that take place during the gear meshing phase. These are in turn dependent on the running load, speed, temperature, lubrication regime and other parameters. So far, the str ...

The presented work is focused on the development of a comprehensive thermo-mechanical model for predicting the temperature rise in thermoplastic polymer spur gears with any desired profile geometry while running. The specific constitutional behavior of thermoplastics influences the gear-meshing patt ...

gear metrology;injection moulding;geometrical quality parameters;polymer gears;
Injection moulding is currently the most widely employed production method for polymer gears. Current standardised gear metrology methods, which are based on metal gear inspection procedures, do not provide the key information regarding the geometric stability of injection moulded gears and are insu ...

The nonlinear material properties of thermoplastics like polyoxymethylene (POM) can influence the thermo-mechanical response of polymer gears to applied running loads. In the presented study, the non-elastic strain rate- and temperature-dependent mechanical characteristics of POM are examined, along ...

This study focuses on investigating the fatigue and wear behaviour of carbon fibre reinforced polymer (CFRP) gears, which have shown promising potential as lightweight and high-performance alternatives to conventional gears. The gears were fabricated via an autoclave process using an 8-layer composi ...

Gear assembly errors are an important contributor to a premature gearbox failure. This study investigates the effects of center distance deviation on polymer gearbox life. The main focus was on the influence on the stress state of the gear. Reference spur gears (m = 1 mm, z = 20, b = 6 mm) with a st ...

Accurately manufactured gears require a reliable, holistic, and fast inspection method. Standardised geometrical parameters enable a consistent and regulated inspection of gears; however, current inspection methods include only a limited set of measurements for gears at specific locations. Therefore ...

Laminated composites have so far received little attention as a potential material for gear drive applications. In the presented study, the thermomechanical performance of a newly developed type of epoxy impregnated, autoclave-cured carbon fibre-reinforced polymer gear-running in pair with a steel p ...
