压榨机辊轴轴颈磨损面的焊接工艺

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.

联立基于平均流量模型的广义Reynolds方程、三维能量方程和固体热传导方程等,计算了计及热效应时,不同表面形貌和轴颈倾斜角下的轴承油膜压力、油膜温度、油膜反力、端泄流量、摩擦系数和保持轴承稳定工作的力矩。

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

25 F型引风机主轴轴颈损坏的原因进行分析,介绍了现场修复轴颈的方法,为延长类似主轴使用寿命提供经验。

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.

针对铁路客车轴承与轴颈人工测量效率低、成本高、劳动强度大、精度差等缺点,研制了一套客车轴承与轴颈尺寸的测量系统,能够完成尺寸的测量、数据存储、通信和管理工作。

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.
