FIELD: measurement technology, mechanical engineering. SUBSTANCE: gear to determine wear-out of rubbing surfaces includes light-emitting diode connected to power supply unit. Light-emitting diode is built in fibre-optical light guide coupled to optical lens and photodetector of matrix type composed of photodiodes and connected to signal converter-amplifier coupled to microprocessor which is linked to information input device and digital indicator and to interface for communication with computer. EFFECT: increased accuracy of measurements, automation of measurement process, creation of capabilities for measurements without disassembly of units, prediction of wear-out. 1 cl, 2 dwg |
