The invention relates to a mechanical friction and
adhesion coefficient measuring device, which is used to measure the
friction coefficient or
adhesion coefficient of a piece to be tested, including a frame, a
drive shaft, a friction disc, a force transmission shaft, a force measuring mechanism, Pressing mechanism and thrust mechanism, one end of the
drive shaft is connected to the external drive device, and the other end is connected to the friction plate, the thrust mechanism and the test piece are sequentially installed on the force transmission shaft, and the test piece is in contact with the friction plate , one end of the force transmission shaft is connected to the force measuring mechanism, and the pressing mechanism is arranged at the other end of the force transmission shaft; the external driving device rotates the
drive shaft, drives the friction disc to rotate, and simultaneously the force transmission shaft rotates in the
vertical plane, By adjusting the pressing mechanism and the thrust mechanism, the force applied to the test piece is changed, and the
friction coefficient or
adhesion coefficient of the test piece is obtained according to the torque measured by the force-measuring mechanism. Compared with the prior art, the invention has the advantages of high reliability, simple operation, low cost and the like.
