Abstract

Mjerenje i kontrola proizvedenih prstena ležajeva od strane poduzeća Feroimpex automobilska tehnika d. o. o. iz Zagreba ključan je dio proizvodnog procesa. Dosadašnji način mjerenja prstena ležajeva podrazumijevao je korištenje standardnih kontaktnih metoda, kod kojih se pojavljuje niz problema, kao što su izrada posebnih postolja za kontrolu različitih proizvoda, korištenje velikog broja mjernih ura, vrijeme potrebno za kontrolu te utjecaj operatera na točnost rezultata mjerenja i pojavu nesukladnosti.

U prvom dijelu rada su opisane postojeće metode mjerenja prstena ležaja. U drugom dijelu su opisane dvije metode mjerenja ležajeva koje su ostvarene u projektu Inovativna hrvatska rješenja za globalnu automobilsku industriju. Prva metoda podrazumijeva postav za beskontaktno mjerenje gdje je opisan rad sustava, osnovne komponente, karakteristike i provedena su mjerenja na sustavu s ciljem dobivanja rezultata ponovljivosti sustava. Druga opisana metoda je sustav za kontaktno dimenzijsko mjerenje prstena ležajeva. Navedene su osnovne komponente sustava, tehničke specifikacije, njegove karakteristike i analizirani rezultati mjerenja. Za statističku obradu podataka dobivenih rezultata mjerenja iz kontaktnog sustava korišten je program Minitab 19 (probna verzija). Eksperimentalna mjerenja beskontaktnog sustava provedena su na Fakultetu strojarstva i brodogradnje Sveučilišta u Zagrebu.

Abstract (english)

A key part of the successful production process in making of bearing rings is ensured thanks to quality control, in the company Feroimpex automobilska tehnika d.o.o. from Zagreb. The previous method of measuring a bearing ring has involved the use of standard contact methods, which have several problems, such as time constraints, making a special jig for different products and using multiple dial gauges.

The first part of the paper describes the existing methods of bearing ring measurement. The second part describes two bearing measurement methods that were realized in the project “Inovativna hrvatska rješenja za globalnu automobilsku industriju”. The first method involves a setup for non-contact measurement where the operation of the system is described, the basic components, characteristics and measurements are performed on the system in order to obtain the results of system repeatability. Another method described is a system for contact dimensional measurement of bearing rings. The basic components of the system, technical specifications, its characteristics, and analysis results are listed in the paper. The Minitab 19 program (trial version) was used for statistical processing of data obtained from the measurement system. Experimental measurements of the non-contact system were performed at the Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb.
