轴颈

When the rotor bearing journal of turbine-generator unit and the collector ring of generator are damaged, we can restore them on-line by TR series which are the systems that the rotor bearing journal of large-scale rotary machine is lathed subtly on-line and burnished.

汽轮发电机组的转子轴颈和发电机的集电环损伤可利用TR系列"大型回转机械转子轴颈在线精车与珩磨系统"进行在线修复，其精度可达到国际先进水平，在线修复可避免大范围拆装主设备，避免返厂加工的长途运输，可节省大量的检修时间，具有显著的经济效益。

The second set of scenarios: Journal wear parts of liner with the first scenario, the first correction series water roll excircle and journal excircle parts machining rounding, trimming good necks confecting tight fit of steel casing.

第二套方案：轴颈磨损部位镶套同第一种方案，不后订正串火辊外方，并不兵轴颈外方部位加工方整，再在整理好的轴颈上配制不松打扰的钢套。

In order to reduce the axle journal of mechanical strength loss, grinding the shaft seating surface wear uneven Department just to Polish it, and then to the journal after Polish excircle size, choose a higher wear resistance ZQAl7-1.5-1.5 bronze, confecting a plain bearings again, replacing the original linear ball bearing.

为了减多轴颈的板滞强度吃亏，磨削的尺寸以轴颈表背磨损不服处恰好磨平为好，再以磨平后的轴颈外方尺寸为基准，采取耐磨性能较矮的ZQAl7-1.5-1.5青铜合金，从头配制一只滑动轴承，替代本来的曲线滚珠轴承。

. As a result, the oil film character of tilting pad would be changed into that of the finite arc cylindrical bush, with the bearing centre , the axle journal centre , the eccentricity and the angle of displacement .

假定开始时轴颈是没有运动的，如图1所示，瓦块圆弧中心、轴颈中心以及瓦块支点处于同一直线上，轴颈中心和瓦块中心间距离定义为原始偏心。

Has the ability to purge through the trunnion to keep both the trunnion and the cavity clean.

有能力冲洗整个轴颈，保持轴颈和空穴清洁。

When the rotor bearing journal of turbine-generator unit and the collector ring of generator are damaged, we can restore them on-line by TR series which are the systems that the rotor bearing journal of large-scale rotary machine is lathed subtly on-line and burnished.

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。

By employing coordinate transformation, the overall generalized displacement vector relevant to the motion of pad and axle journal is converted into axle journal displacement vector in a local motion coordinate system, and the oil film force in a partial motion coordinate system is obtained by solving the dynamic characters of a fixed bush bearing.

通过坐标变换，将瓦块和轴颈运动相关的全局广义位移矢量转换为局部动坐标系下轴颈的位移矢量；利用求解固定瓦轴承动力特性的方法求得的局部动坐标系下的油膜力。

The results show that the pad tilting angle in static equilibrium is related to the structural parameters of pad, eccentricity of axle journal to pad, and elearance ratio, but is unrelatrd to the axle journal speed, viscosity of oil film, etc.

研究表明，瓦块静平衡摆角只与瓦块结构参数、轴颈相对瓦块偏心率，间隙比有关，而与轴颈转速、油膜粘度等无关。

The assembly of journal and plain bearing liner space is too little, force of organic still oil pressure is small it is the crucial index that affects lubricant result, make lubricate because of lacking engine oil between crankshaft and plain bearing liner and bite dead invalidation, include to be pulled badly, lack lube, layer of alloy of dry attrition generation is fused, grind sliding surface to did not maintain the oily film of certain ply, and all sorts of local overload exhaustion are destroyed, cavitation erosion and V form are destroyed etc, through technology of him director diesel locomotive old experience reachs the analysis of pair of its breakdown reasons, put forward precautionary measures especially. As a result of,the burns caustic mechanism plain bearing liner to burn caustic mechanism of 1 plain bearing liner is the lube film burst between journal and plain bearing liner, cause plain bearing liner and crankshaft generation clash, below high temperature, high pressure and high rotate speed, the wear-resisting alloy layer of plain bearing liner wears away prematurely or fuse, cause plain bearing liner and crankshaft to stick thereby bite, can make the steel back of plain bearing liner and Kong Zhong produces whirligig, inlet port is jammed, carry on the back by steel again with the friction of aperture causes high temperature to make plain bearing liner burned-out further, can cause bolt to break off, happen swing a malign accident that pounds cylinder body of bad internal-combustion engine.

轴颈和轴瓦的装配间隙太小，还有机油压力低是影响润滑效果的关键指标，使得曲轴和轴瓦之间因缺少机油润滑而咬死失效，包括严重拉伤，缺少润滑油，干摩擦产生合金层熔化，磨滑面没有保持一定厚度的油膜，以及各种局部过载疲惫破坏，气蚀和V形破坏等，通过本人主管内燃机车技术多年经验及对其故障原因的分析，特提出预防办法。1轴瓦的烧损机理轴瓦烧损的机理是由于轴颈和轴瓦之间的润滑油膜破裂，导致轴瓦和曲轴产生摩擦，在高温、高压和高转速下，轴瓦的耐磨合金层过早地磨损或熔化，从而引起轴瓦和曲轴粘咬，会使轴瓦的钢背和座孔中产生旋转运动，进油孔被堵塞，再由钢背和座孔的磨擦进一步引起高温使轴瓦烧坏，并会造成螺栓折断，发生甩出捣坏内燃机缸体的恶性事故。
