Abstract

To perform precise measurement on mega gears

the principle of mega-gear in-site measurement system with laser tracker and corresponding key techniques are originally introduced. Considering the mega-gear in-site measurement system with laser tracker integrates the large-scale measurement capacity of laser tracker and the high accuracy of coordinate measuring machine

the laser tracker is used to establish the coordinate system both for mega gears and the Three-coordinate Measurement Platform (TMP)

thereby

their coordinate systems are associated by the coordinate system of the laser tracker

and the module and algorithm of coordinate system fitting are proposed simultaneously. Meanwhile

a novel module of attitude adjustment of TMP is established

which can be accomplished by the system of attitude adjustment to ensure that the position relationship between TMP and the axis of gear can meet the measuring requirements. The results illustrate that the principle of mega-gear in-site measurement system with laser tracker is correct and feasible

and in consequence it can meet the six grade precision measurement requirements of mega gears.
