**课程名称：** 激光轴对中 - 可靠性工程 **课程概述：** 轴错对是导致旋转机械故障的四大原因之一，占所有相关维修成本的50%以上。精确的轴对中可以预防大量的机械故障，并显著减少因计划外停机造成的生产损失。 本课程旨在帮助所有对轴对中重要性感兴趣的人士，包括但不限于：机械工程师、电气工程师、可靠性经理、船舶经理、技术总监、船长、船厂技术人员、验船师、保险检查员、船舶设计师、轮机工程师等。 经过精密轴对中的机器运行时间更长，运行成本更低。错对会大大缩短轴承、密封件、轴和联轴器的寿命。本课程将概述对中效益、软脚校正、百分表和激光对中方法，以及设备移动技巧。 **适合人群：** * 希望成为轴对中专家的初学者。 * 希望了解轴对中、其效益及激光对中程序的学员。 **电机轴对中的重要性：** 正确的电机轴对中可以延长旋转机械的运行寿命。为了实现这一目标，必须确保最易发生故障的部件在可接受的设计范围内运行。 尽管轴错对对电机效率没有可测量影响，但正确的轴对中可以确保电机与驱动设备之间平稳高效的动力传输。轴错对会导致过度的振动、噪音、联轴器和轴承温度升高，以及轴承、联轴器或轴的过早失效。 **电机错对类型：** 1. **角度错对：** 电机与驱动设备之间存在角度偏差。 2. **平行错对：** 两轴中心线平行，但不在同一线上。 3. **组合错对：** 电机轴同时存在角度错对和平行错对。 大多数大型电机直接与负载通过刚性或柔性联轴器连接。刚性联轴器无法补偿电机与驱动设备之间的错对。柔性联轴器也能在设备之间起到一定的减振作用。 完成本课程后，您将获得基础的轴对中知识，为成为机械对中专家奠定基础。 **课程内容（讲座）：** * 对中定义 * 对中方法 * 错对类型 * 错对原因 * 错对影响 * 错对迹象
Shaft misalignment is responsible for as much as 50% of all costs related to rotating machinery breakdowns. Accurately aligning shafts can prevent a large number of machinery breakdowns and reduce much of the unplanned downtime that results in a loss of production.The Shaft Alignment course is aimed at anyone interested in understanding the importance of shaft alignment. This may include: Mechanical, Electrical Engineers, Reliability Managers, , Ship Managers, Technical Superintendents, Ship Masters, Shipyards Technical Staff; Surveyors; Insurance Inspectors; Naval Architects; Marine Engineers; Etc.Machines that have been precision aligned run longer, and cost less to run. Misalignment greatly reduces the life of bearings, seals, shafts and couplings. This course will provide an overview of the benefits of alignment, soft foot correction, dial-indicator and laser alignment methods, and how to move the machine.Who should attend?The shaft alignment course is ideal if you want to start your career as an expert in shaft alignment.On the other hand, if you want to know more about shaft alignment, its benefits, laser alignment procedures, then this course will give you a very good introduction.The Importance of Motor Shaft AlignmentProper motor shaft alignment increases the operating life span of rotating machinery. To achieve this goal, components that are the most likely to fail must be made to operate within their acceptable design limits.While misalignment has no measurable effect on motor efficiency, correct shaft alignment ensures the smooth, efficient transmission of power from the motor to the driven equipment. Misalignment produces excessive vibration, noise, coupling- and bearing-temperature increases, and premature failure of bearings, couplings or shafts. There are three types of motor misalignment:Angular misalignment occurs when the motor is set at an angle to the driven equipment.Parallel misalignment occurs when the two shaft centerlines are parallel, but not in the same line.Combination misalignment occurs when the motor shaft suffers from both angular misalignment and parallel misalignment simultaneously.Larger motors are usually directly coupled to their loads with rigid or flexible couplings. Rigid couplings do not compensate for motor-to-driven-equipment misalignment.Flexible couplings also can reduce vibration transmitted from one piece of equipment to another.By completing the Alignment Fundamentals course, you will gain the basic knowledge of alignment that will help you in becoming an expert in machinery alignment.Our course is comprised of the following lecturers: Alignment DefinitionAlignment MethodsTypes of MisalignmentCauses of MisalignmentEffects of MisalignmentIndications of Misalignment
