DEVICE FOR FRICTION TEST IN INVESTIGATION OF FRETTING FATIGUE

摘要

The invention relates to a friction material testing m .. The aim - increase in the accuracy of test results. The apparatus comprises a body, holders of a flat sample 12, which are mounted in the guides 24 and 25 for moving the latter in the perpendicular plane of contact of the sample 12 and kontrobraztsov 10 and 11 toward the mechanisms 26 and 27 provide a static and dynamic loads associated with the respective guide 24 and 25, the pressing mechanism with equal force kontrobraztsov 10 and 11 to the sample 12, which is coupled to the housing by means of an axis 15 perpendicular to the plane passing through the axis of the specimen holder and the guide, the frictional force meter, configured a first dynamometer 19 which through swivel 18 is coupled rigidly with the pressing mechanism attached to arm 17. 1 yl. with G
