Abstract
Kako bi se dobili što točniji podaci o nosivosti zupčanika, potrebno je provoditi ispitivanja u uvjetima što sličnijima onima u eksploataciji. Ispitni uređaji koji se pri tom koriste dijele se na uređaje s otvorenim i zatvorenim tokom snage. Iako su uređaji s otvorenim tokom snage konstrukcijski jednostavniji, pogodni su samo za kratkotrajna ispitivanja budući da se sva energija koju daje pogonski stroj pretvara u toplinu. Kako bi se smanjio utrošak energije pri dugotrajnim ispitivanjima zupčanika, koriste se uređaji sa zatvorenim tokom snage. S obzirom na princip rada, dijele se na uređaje s mehaničkim i električkim zatvorenim tokom snage. Tema ovoga rada je konstruiranje ispitnog uređaja sa električki zatvorenim tokom snage. Prednost ovog uređaja naspram drugih sličnih uređaja je što kod podešavanja osnog razmaka nije potrebno pomicati motore niti vršiti dotezanje remena jer se snaga na pomično vratilo dovodi preko stožničkog para i klinastog vratila. Na ovaj način ubrzana je izmjena osnog razmaka, a posao za operatera je olakšan. Dodatno olakšanje kod podešavanja osnog razmaka napravljeno je uvođenjem senzora za mjerenje istog, koji eliminira potrebu za ručnim mjerenjem. Dodavanjem jedinice za kondicioniranje ulja omogućeno je ispitivanje zupčanika sa širokim rasponom temperatura maziva.
Abstract (english)
In order to obtain the most accurate data on gear flank and root strength, testing needs to be done in conditions as similar as possible to those in exploatation. Testing rigs used for such tests can be divided into two main groups – rigs with open and rigs with closed power loop. Open power loop rigs have simple design but they are suitable only for short duration testing since all rotational energy is converted into heat. In order to minimize power consumption, closed power loop rigs are used for long duration testing. They can be divided into rigs with mechanically and electrically closed power loop. Subject of this thesis is design of gear testing rig with electrically closed power loop. In contrast to other similar testing rigs, this one does not require moving the motors or retightening the belts after changing axis distance of test gears. This is due to the fact that power is brought to movable shaft via bevel gear pair and spline shaft. By employing this solution, axis distance changing is faster and easier for the operator. Additional help with axis distance changing is introduced with sensor for measuring axis distance which eliminates the need for manual axis distance measurement. Oil conditioning unit enables gear testing with wide range of lubricant temperatures.
