As the factor of clearance, bearing chamfer, oil groove etc, The actual load is higher than theory of calculation.

由于受配合间隙、材料强度、轴承倒角、内部油槽等原因的影响，轴承的真正承载面压会大于理论计算值。

As the factor of clearance,bushes chemfer,oil groove etc.,the actually loadis higher than theory of calculation.

由于受配合间隙、材料强度、轴承倒角、内部油槽等原因的影响，轴承的真正承载面压会大于理论计算值。

First, smelters, mines, steel plant machinery and equipment endurance pressure rolling bearings.

Aimed at all kinds of damage phenomena in the sleeve usage of oil-film bearing in the backup roll of Baoshan 1580 hot strip mill,during the process of elastic conjunction between sleeve and rollneck,deformation and load properties are quantitatively analyzed by boundary element method for 3D elastic and plastic contact problems.

针对宝钢1580热连轧机精轧机组支承辊油膜轴承锥套使用中存在的各类损伤问题，利用三维弹塑性接触问题边界元法定量分析了轧机油膜轴承锥套与轧辊辊颈过盈装配过程中的变形和载荷特性，得出了装拆过程中不同的胀型压力和轴向推力条件下锥套接触压力延母线方向的变化规律，同时锥套端部和密封槽附近接触压力峰值的存在是加速锥套损伤及降低其使用寿命的重要原因。

1 In Zhanjiang Power Plant has been analysed,and it is believed that the main causes to be as follows:(1)large deformation of the lowpressure cylinder leading to collision and friction between moving and stationary parts;(2)the vacant space under bearing pedestal and turninggear box bringing on lower rigidity;(3) the natural frequency of bearing pedestal is closing to the power frequency etc.

对湛江发电厂1号机4号轴瓦振动大的问题进行分析，认为其主要原因为：低压缸变形大导致动静碰摩，轴承座及盘车箱下部脱空引起刚度降低，轴承座的固有频率与工频相近等。

Electronically tested, repacked bearings shall be acceptable in units that do not have a high incidence of bearing failure.

经过电子测试和重填黄油的轴承在那些轴承损坏率低的电机中是可以用的。

The tile axis's ZWZ brand bearing has the honor to receive the state-level: The Chinese well-known trademark, China famous brand goods, the quality exempting from inspection product, China export honors and so on recommendation product, the product widely apply in domains and so on railroad, automobile, metallurgy mine, machinery, petroleum, papermaking, engine bed, cement, wind electricity, aviation, the selling to domestic more than 6000 users and the world more than 80 countries and the area.
