The Research and Design of Transmitting Large Torque with Large Universal Shaft of Large Interference Joint;

Theoretical and Experimental Research on Interference Fit Friction Coefficient;

Taking account of the randomness of the parameters for designing the interference fit of rolls and their shafts, this paper regards the interference-fit strength of the rolls and their shafts, shaft strength and roll strength as a series system, and puts forward a reliability-design model for the interference fit of the rolls and shafts on the basis of the system reliability.

Probability mathematical model of interference fit was derived and the reliability of interference fit was analyzed thoroughly, It is known that diameter reduction of the fit will reduce breaking magnitude of interference and length reduction of the fit will increase least magnitude of the interference essential for transmission, both of them will drop reliability of the interference fit.

The effect of angle windage on the linking intensity of interference fits;

On the basis of analyzing the pressure change aroused by angle windage on linking length, this thesis presents a math model of circle moment for interference fits in the dissimilarity of generatrix angle, then states the effects opposite circle moment because of angle windage, thus, to provide reference for the design of taper interference fit
