The invention relates to a method for predicting the friction coefficient of a keyless joint surface. The method mainly solves the technical problems that the friction coefficient of the keyless connection joint surface cannot be accurately given and a prediction method is lacked. The method comprises the following steps: 1) calculating the pressure p1 of the contact surface of a spindle and a shaft sleeve according to elastic mechanics; 2) substituting the pressure p1 of the contact surface of the main shaft and the shaft sleeve into a torque formula to obtain a friction coefficient of the contact surface of the main shaft and the shaft sleeve; (3) the expansion sleeve enables the outer ring to axially move through screwing of a bolt, the moving distance is called as an assembly stroke e,and a relational expression of the assembly stroke and the magnitude of interference is obtained; 4) performing torque capacity experiments under different assembly strokes to obtain a relation tableof the assembly strokes, the magnitude of interference and the torque, and combining formulas (1)-(3) to obtain a friction coefficient value; and 5) obtaining a nonlinear fitting function based on adifferential evolution method, and respectively determining relational expressions of the magnitude of interference, the assembly stroke and the friction coefficient so as to establish a prediction model of the magnitude of interference and the assembly stroke for the friction coefficient.
