Paper Abstract

This paper presents an approach to measuring the coaxiality of a shafting and bearing system for large and medium-sized ship using CMOS (Complementary Metal Oxide Semiconductor) image sensor. The measurement system consists of a laser diode with single mode fibre pigtail, which generates a reference datum-line, and position sensor of centre of shafting or bearings that is composed of a CMOS image sensor and a rotating inductance displacement transducer. The experimental results show that the approach meets the precision requirement of the coaxiality measurement. It provides flexibility and costs less. The method can also be applied to the positioning and accurate coaxiality measurement of similar bearing holes of large-scale axles.
