Description

Изобретение относитс  к методам триботехнических испытаний в машиностроении и  вл етс  усовершенствованием известного, способа по основному авт, св. № 405056. The invention relates to the methods of tribotechnical testing in mechanical engineering and is an improvement of the known, method according to the basic author, St. No. 405056.

Цель изобретени  - повышение точности определени  коэффициента тре- :НИЯ путем учета динамических параметров одного из элементов пары трени  при его качении по другому элементу. Ма чертеже Схематически изображе- но устройство дл  реализадии предлагаемого способа.The purpose of the invention is to improve the accuracy of determining the coefficient of the three-: NII by taking into account the dynamic parameters of one of the elements of the friction pair as it rolls on the other element. Ma drawing Schematically shows a device for the implementation of the proposed method.

Устройство содержит поворотную |платформу 1, держатель 2 образца, в {качестве которого может служить плос- jкость, слой смазки и т.п. , держатель Iконтрообразца 3 (не показан), физи- :ческий ма тник 4 и акселерометры 5 и 6. The device contains a rotary platform 1, a sample holder 2, in which quality can serve as a plane, a layer of lubricant, etc. , the holder of an I sample 3 (not shown), a physical tandem 4 and accelerometers 5 and 6.

Способ осуществл ют следз;ющим образом .The method is carried out in a following way.

I Контробразец 3, выполненный в ви- |де тела вращени , жестко закрепл ют :в физическом ма тнике 4, который ус- ;Танавливают на держателе 2. Наклон :ют держатель 2 под острым углом б к I горизонту. При фиксированном угле 0 измер ют угол ( отклонени  оси физического ма тника, который всегда меньше 9 . С помощью акселерометров 5 и 6 определ ют величину и направление линейных ускорений точек О и СI Contrast 3, made in the form of a body of rotation, is rigidly fixed: in a physical workbench 4, which is set; Tanned on the holder 2. Tilt: the holder 2 is at an acute angle b to the I horizon. At a fixed angle of 0, the angle is measured (deviations of the axis of the physical model, which is always less than 9. With the help of accelerometers 5 and 6, the magnitude and direction of the linear accelerations of points O and C are determined
