Abstract

Изобретение относитс  к области машиностроени , в частности к устройствам дл  измерени  момента трени  подшипников. Цель изобретени  - повышение точности измерени  переменной составл ющей момента трени . При вращении вала 1 посто нна  составл юща  момента сопротивлени  под- шипника 2 регистрируетс  по отклонению упругого элемента 8, на которой воздействует посредством рычага 4 оправки 3 упор 9 бруска 7. Переменна  составл юща  момента трени  определ етс  по его отрицательной амплитуде, котора  регистрируетс  упругим эле-г ментом 6. малой жесткости, зажатым между упорами 5 рычага 4 без иска жений. 4 ил.The invention relates to the field of engineering, in particular, to devices for measuring the moment of friction of bearings. The purpose of the invention is to improve the measurement accuracy of the variable component of the frictional moment. When the shaft 1 rotates, the constant component of the moment of resistance of the bearing 2 is registered by the deflection of the elastic element 8, which is acted upon by the lever 4 of the mandrel 3, the stop 9 of the bar 7. The variable component of the friction moment is determined by its negative amplitude, which is recorded by the elastic element -grout 6. low stiffness, sandwiched between the stops 5 of the lever 4 without distortion. 4 il.
