Abstract
The invention discloses a method and a device for measuring actual static frictional torque of a rolling bearing. The method is that a transmission shaft is mounted into an inner ring hole in the measured rolling bearing, and the measured rolling bearing is synchronously fixed into a bearing hole in a supporting seat; a counterweight plate and a rotating plate are respectively fixed to two ends of the transmission shaft, wherein the radius of the outer circle of the rotating plate is R; a lifting line coils the rotating plate; a supporting plate is suspended at one end of the lifting line; the acting torque of the supporting plate applied to the rotating plate through the lifting line is less than the actual static frictional torque M of the measured rolling bearing, so that the rotating plate is static, and fine iron sand is gradually added to the supporting plate; when the rotating plate starts to rotate, the fine iron sand is stopped adding, the sum of the weight of the supporting plate and the added fine iron sand is W, and thus the actual static frictional torque M of the measured rolling bearing is M=W*R. The method and the device have the advantages of being simple in structure, small in cost, convenient to operate, relatively high in measurement precision, and particularly suitable for large, medium and small scale enterprises and labs.
