DEVICE FOR MEASURING NORMAL ELASTICITY MODULUS IN PLAIN BEARINGS Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: amount of light passed through given section of bearing shell is proportional to tension or compression in this section. Light with narrow spectral range goes from infrared range emitter 1 through radial hole in bearing housing to shell material over its radius counter-clockwise and to photodetector 2, parametric amplifier 3, luminous load detector 4, which is essentially differential stage with adjustable gain. EFFECT: improved measurement accuracy. 2 cl, 3 dwg
