▎ 摘　　要

NOVELTY - The device has an assembling supporting frame (4) provided with a torque wheel mechanism (5). A rear side of the supporting frame is provided with a torque motor. A top side of a panel is provided with a lubricant box mechanism (6). A right side of the lubricant box mechanism is provided with a pump body (10). An input end of the pump body is fixed with a bottom side of the lubricant box mechanism by a pipeline. An output end of the pump body is provided with an infusion tube. Another end of the infusion tube is fixed with a coating mechanism. A top side of a base (1) is located on a lower side of the torque wheel mechanism that is provided with a lubricant collecting mechanism (7). A right side of the base is orderly provided with a display screen and a programmable logic controller (PLC) (8). A right side of a hollow block is uniformly provided with a wetting brush hair. An outer side of a locating rod is fixedly sleeved with a torque wheel. USE - Ergometer integrated graphene lubricant friction coefficient testing device. ADVANTAGE - The pump body pumps graphene lubricant in the lubricant box to the hollow block through the infusion tube so that the wetting brush hair is wetted by a leakage hole on the hollow block such that the driving torque motor drives the locating rod so as to rotate the torque wheel, thus uniformly coating an outer side wall of the torque wheel with the graphene lubricant, improving graphene lubricant friction coefficient testing stability, precision and efficiency and reducing labor intensity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an ergometer integrated graphene lubricant friction coefficient testing method. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of an ergometer integrated graphene lubricant friction coefficient testing device.
