The quality of gear manufacturing significantly influences the way load is distributed in meshing gears. Despite this being well-known from practical experience, gear quality effects were never systematically characterized for polymer gears in a manner able to account for them in a standard calculat ...

V doktorskem delu je obravnavana problematika konstruiranja polimernih zobnikov. Predlagan je model za preračun polimernih zobnikov s progresivno ukrivljeno ubirnico, t. i. S-ozobjem. Pri postavitvi modela za S-ozobje smo izhajali iz uveljavljenih modelov za preračun kovinskih in polimernih zobnikov ...

V diplomski nalogi smo preučevali utrujanje polimernih zobnikov ob cikličnih upogibnih obremenitvah. Zaradi utrujanja materiala se lahko pojavijo razpoke, katerih rast vodi v lom zoba. Kritični prerez na korenu zoba, določen s 30° tangento, je bil analiziran na osnovi teoretičnih in numeričnih izrač ...

The potential for replacing the fossil-based Polyoxymethylene (POM) and Polyamide 66 (PA 66) in polymer gear applications with a bio-based Polyamide 6.10 (PA 6.10) was studied and is presented in the article. The use of bio-based plastics is increasing but mostly in undemanding applications like pac ...

The study aims to investigate the possibility of employing machine learning models in the design of non-involute gears. Such a model would be useful for design calculations of non- standard gears, where there are no available guidelines. The aim is to create a decision- support model accompanying th ...

Napaka montaže zobnikov predstavlja pomemben doprinos k predčasni odpovedi gonila. V sklopu magistrske naloge smo obravnavali vpliv napake medosne razdalje na življenjsko dobo polimernih zobnikov. Uporabili smo ravnozobe valjaste zobnike z evolventnim profilom ozobja. Glavni poudarek pri raziskovanj ...

The article presents a comprehensive study on the tooth bending strength of spur gears with a progressive curved path of contact, or so-called S-gears. Systematic gear meshing simulations were conducted to study the effects of S-gear geometry parameters on tooth bending strength. Different S-gear ge ...

Gear-manufacturing quality affects the load sharing between the meshing gears as well as the load distribution along the width of the tooth. This study aims to investigate the effect of gear-manufacturing quality on the mechanical and thermal states of polymer-gear pairs and consequently on their li ...

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 ...
