Sažetak
In the paper the bearings maintenance system and wear measurements are analysed. Continuous and dedicated efforts of engineers have led to improvements of this system as it has evolved from manual measurements and use of old tools and measurement instruments to a sophisticated software for precise measurement and alerting. Along with technological advances, in an effort to make improvements and prevent failures and/or damages, the monitoring and measurement systems of this fundamental part of marine engines have been developed. The need for safer, higher quality and more reliable measurements of bearing wear has led to development of software providing such services on the market for engineers all over the world. These systems have also been improved and upgraded in accordance with the ship owners' requirements, depending on the type of ship and requirements of the crew involved. AMOT system is the type of software enabling complete control over the bearing condition, wear and monitoring of all parameters directly on the screen. Furthermore, one of the advantages of the system is flexible installation, arrangement of monitoring units and installation of sensors. Moreover, special attention has been paid to monitoring bearing wear as well as measurements, both manually and by application of AMOT system within a period of time. Due attention has been given to the very AMOT system as well, installation, operation, handling, options and requirements for instalment, sensors, i.e. their installation and arrangement. Attention has also been given to the crankshaft, crankshaft deflection and deflection measurements, as well as correlation between deflection and bearing wear. Since in maritime industry the correlation between crankshaft deflection and bearing wear is well known, due attention has been given to taking and recording measurements as well as their calculations in order to reduce or prevent these two occurrences that have been happening ever since the invention of internal combustion engines. Nevertheless, as the sophisticated monitoring system is analysed, parts of AMOT system have been included in the analysis as well as system interface, signal processing unit, dimensions and technical characteristics.
