Noise control of needle bearings

The bachelor thesis deals with the noise of needle bearings. By analysing the noise of the bearings, it is possible to find out the technical condition of the bearing and reveal the types of bearing damage. The beginning of the work is devoted to the theory of bearing noise. Vibration diagnosis methods are described. In the practical part, a manual noise meter is tested, and the investigated values are evaluated by a system for measuring the noise of bearings. The primary objective of this thesis is to find out how the noise of the bearings could be controlled more effectively

Noise control of needle bearings

Bakalárska práca sa zaoberá hlučnosťou ihlových ložísk. Analyzovaním hlučnosti ložísk je možné zistiť technický stav ložiska a tiež odhaliť typy poškodenia ložísk. Začiatok práce je venovaní teórii hlučnosti ložísk. Sú popísané metódy diagnostiky vibrácií. V praktickej časti je testovaný manuálny hlukomer a sú skúmané hodnoty vyhodnotené systémom na meranie hlučnosti ložísk. Hlavnou úlohou práce je zistiť ako by sa dalo efektívnejšie kontrolovať hlučnosť ložísk.The bachelor thesis deals with the noise of needle bearings.
