Study on welding technology of abrasive surface of journal of presser roll shaft;

The film pressure,film temperature,load-carrying capacity,end leakage flow-rate,frictional coefficient and misalignment moment of a journal bearing with different journal misalignment angle and surface roughness are calculated based on generalized Reynolds equation,three-dimension energy equation and solid heat conduction equation etc,considering thermal effect.

This paper analyzes the causes of the damage on the journal of the Y4-73-02No.

A set of measurement system for bearing and axle journal on passenger car has been developed to fulfill the work of measuring the dimension,data saving,communication and data management,which overcomes disadvantage of manual measurement,such as low efficiencies,high cost,high labor intensity and low precision.

In the system, the thought of differential measurement mode and automatic on-line alignment are applied, so as to make the fully automatic non-contact measurement of the train wheel-set journal diameter, dust guard seat diameter and axle journal length.

The scratch repairing technique of stator bearing neck for the home-made 300MW turbine generator

The structure and importance of industrial steam turbine rotor were described,including process the rotating blade groove and bearing neck,scratch cross central line,balance hole line and lock hole line,the processing of rotating blade groove and bearing neck,and how to guarantee the demand for rotor precision in processing were mainly described.
