进行的疲劳强度试验验证结果表明：通过对轴颈圆角半径等局部结构参数的合理选择，可以提高曲轴可靠性。

The experiment and theory proved that the wear resistance and fatigue resistance of the ductile iron crankshaft could be greatly improved,and also the uniform layer of hardness and residual stress could be obtained by the second method-the laser circumference continuously scans the neck of crankshaft,and the laser forms 45°angle with the central line of crankshaft to scan the partial filleted angle of the crankshaft.

实验与分析证明：采用轴颈周向螺旋扫描，过渡圆角处激光束与轴心线成45°角的部分圆角的激光扫描处理方法，更能获得较为均匀的硬化层和残余应力，从而达到了提高曲轴抗磨损，抗疲劳的综合机械性能。

Using this machine,journals,fillets and other areas of a crankshaft can be induction hardened.

该机床能实现曲轴轴颈及圆角等部位的表面感应淬火。

Steel sleeve of inner circle and axle journal repairs b selection of combining precision requirements with tight tolerances.

镶钢套的边方与轴颈拆除处b的打扰不粗度请求采取不松配公役。

Therefore, the offset printing process, in the event of ink color depth of the rollers on channeling, heavy ink roller and roll as well as related and axle journal in line with the inspection of the bearings is essential.

所以，在胶印历程洋，一旦呈现不朱色浅浅纷歧的本体时，差窜不朱辊、匀不朱辊和不沉辊以及不关的与轴颈打扰的轴承的查抄是纷歧不合必定的。

When an axle journal is at a certain position in a bearing, the pad tilting angle is related to initial eccentricity and clearance ratio, but unrelated to speed, viscosity, etc.

当轴颈在轴承中位置一定时，可倾瓦块摆角只与原始偏心和间隙比有关，与转速、粘度等无关

This is the purchase of parts imported equipment, there are certain difficulties, and ride series water roll and axle journal in the design and manufacture of the whole structure, has greatly increased the difficulty of the repair process.

由于该机是出口摆设，采办零件活命着必定的艰难，且该机的串火辊与轴颈在安排和创作发明上是局部拆开布局，大大补充了拆除加工的难度。

, after the axle journal begins to rotate, the characteristic angle of oil film and the original geometric angle of pad have the following relationship

由图1可知，轴颈开始旋转后，油膜特征角与瓦块原始几何角有如下关系

When the clearance ratio is equal to zero, pads cling to axle journal and are unable to tilt, consequently the tilting angle equals zero.

当轴承间隙比为零时，瓦块和轴颈紧贴，瓦块无法摆动，此时摆角为零。

, when the eccentricity is equal to zero, the arc centre of pad and the centre of axle journal are coincident, and the thickness of oil film is constantly C.

当偏心率为0时，如图5所示，瓦块圆弧中心与轴颈中心重合，油膜厚度恒为半径间隙，根据流体润滑理论，无动压效应，压力为0，瓦块摆角为零。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
