FIELD: oil and gas industry.
SUBSTANCE: invention relates to devices for measuring the coefficient of friction of a pair of "metal-rock" and can be used in the oil and gas industry. The device contains the bottom and top plates, load cell and guides. In this case, the load cell is connected to the lower and upper plates through the axle and mounting brackets, and support balls are placed between the upper and lower guides.
EFFECT: development of a device for measuring the coefficient of friction of a pair of "metal-rock", allowing research under conditions of increased axial loads with maximum measurement accuracy.
