Improvement in accuracy of strain gauge measurements for using in high precision measurements of gearboxes efficiency

Abstrakt
The paper describes further development in our research from the previous year [1]. We are still focused on finding a method of measuring the torsion on shafts of gearboxes installed in a real machine to determine their actual efficiency.
The biggest problem is the limited accuracy of our strain gauge apparatus, because of over-sized design of shafts and thus their very small deformations. We still believe that use of various technological and structural notches is an acceptable solution, whereby the level of recorded signal could be amplified by this way.
