Abstract:
     The disclosed measuring apparatus and method for frictional moment comprise: the target bearing with diameter as D is suspended a segment nylon wire with ends connected to weight and dynamometer respectively, when bearing static, the show value on dynamometer as A1 balances to the weight; if rotating toward one direction by some rate, the show value increases to A2, and the formula M=(A2-A1) .D/2 can express the corresponding frictional moment. This invention is reliable, simple, and well practical.
