Cylindrical gears load capacity test rig

Kako bismo izbjegli oštećenja zubi zupčanika, potrebno je točno odrediti dopuštenu opteretivost istih te određene parametre koji utječu na propagaciju oštećenja. Pri radu, kada se prelazi maksimalna nosivost cilindričnih zupčanika, mogu se pojaviti oštećenja kao što su lom zubi, oštećenje bokova zubi, deformacije zubi, habanje te oštećenje neke komponente sustava koje naposljetku dovodi do nefunkcionalnosti samog zupčanog prijenosnika. Detaljna analiza postojećih uređaja na tržištu i postupka ispitivanja maziva prema normi ISO 14635-1:2000, otkrila je neka zadovoljavajuća rješenja koja su odgovarala određenim zahtjevima dodijeljenog zadatka. Na temelju postojećih rješenja i aktualne norme za ispitivanje maziva, nastala su tri koncepta te je odabran onaj optimalan među njima. Odabrani koncept je detaljnije razrađen kroz proračun i tehničku dokumentaciju. In order to avoid the damage of the gear teeth, it is necessary to accurately determine the load capacity of the gears and the parameters that affects the propagation of the crack and the damage to the material. During operation, when the maximum load capacity of the cylindrical gears is exceeded, it causes damage as tooth breakage, damage of the tooth flanks, tooth deformation, abrasive wear and at the end it can cause damages of some components that leads to dysfunctional gear transmission. This thesis describes the development and construction of the device used for measuring of the load-carrying capacity of the cylindrical gears and is also used as gear lubricant test rig. A detailed analysis of the existing devices on the market and according to the ISO 14635-1:2000 standard it came to some solutions that satisfy the specific requirements of this assignment. Based on the existing solutions and the current standard that is used for lubricant testing, it came into creation of the three concepts and it was chosen the optimal among them for subsequent construction that was fully elaborated in a form of both calculation and technical documentation.
