　　我们先来看看该高温电机轴承室磨损的原因：

　　设备长时间运行导致的金属疲劳，金属内部结构并不均匀，从而造成应力传递的不平衡，从而导致磨损。缺乏保养意识，在机器出现振动还没有意识要加注润滑油，没有完善的保养计划。机器在运转过程中没有润滑油出现干磨现象这也加剧了损坏速度，从而导致直接性磨损。

　　电机轴承室磨损现场维修步骤：

　　(1)用氧气乙炔表面烤油，直至无火花四溅为止;

　　(2)磨光机打磨修复面，无水乙醇清洗修复表面，保证修复面粗糙洁净干燥;

　　(3)调和材料SD7101H，涂覆在修复表面;

　　(4)采用基准刮研工艺恢复原始轴径;

　　(5)涂覆完成后，加温固化;

　　(6)固化完毕后，装配开机试运行无异常，修复完毕共用6小时。

　　针对该企业出现的电机轴承室磨损问题，主要原因是平常缺乏设备的保养意识，所以建议大家加强电机的日常维护和保养：

　　1、及时清除高压电机机座外部的灰尘、油泥。如果使用环境灰尘较多的话，每天清扫一次。

　　2、检查高压电机接线端子。检查接线盒接线螺丝是否烧伤、松动等。

　　3、检查各固定部分螺丝，并将松动的螺母拧紧。

　　4、检查传动装置、皮带轮或联轴器有无魄力、损坏，皮带及其联结扣是否完好。

　　5、高压电机的启动设备，要及时清擦外部灰尘，擦拭触头，检查各接线部位是否有烧伤痕迹，接地线是否良好。

　　6、轴承的检查与维护。轴承在使用一段时间后应该清洗，更换润滑脂或润滑油。

　　Let's first look at the reasons for the wear of the bearing chamber of the high-temperature motor:

　　Metal fatigue caused by long-time operation of equipment and uneven internal structure of metal, resulting in unbalanced stress transmission and wear. Lack of maintenance awareness. When the machine vibrates, they are not aware of filling lubricating oil, and there is no perfect maintenance plan. During the operation of the machine, there is no lubricating oil and dry grinding occurs, which also aggravates the damage speed and leads to direct wear.

　　Field maintenance steps for wear of motor bearing chamber:

　　(1) Bake oil on the surface with oxygen and acetylene until there is no spark splashing;

　　(2) Polish the repair surface with a grinder and clean the repair surface with absolute ethanol to ensure that the repair surface is rough, clean and dry;

　　(3) Blending material sd7101h, coated on the repair surface;

　　(4) Restore the original shaft diameter by using the benchmark scraping and grinding process;

　　(5) After coating, heat and cure;

　　(6) After curing, the assembly, startup and trial operation are normal, and it takes 6 hours after repair.

　　In view of the wear problem of motor bearing chamber in the enterprise, the main reason is the lack of equipment maintenance awareness. Therefore, it is recommended to strengthen the daily maintenance and repair of motor:

　　1. Remove the dust and oil sludge outside the high-voltage motor base in time. If the use environment is dusty, it is best to clean it once a day.

　　2. Check the wiring terminal of high voltage motor. Check whether the wiring screws of the junction box are burned, loose, etc.

　　3. Check the screws of each fixed part and tighten the loose nuts.

　　4. Check whether the transmission device, pulley or coupling is strong and damaged, and whether the belt and its coupling are intact.

　　5. For the starting equipment of high-voltage motor, the external dust shall be cleaned in time, the contact shall be wiped, and the wiring parts shall be checked for burn marks and whether the grounding wire is in good condition.

　　6. Inspection and maintenance of bearings. The bearing should be cleaned and replaced with grease or lubricating oil after being used for a period of time.
