导轨滑块作为机械传动中的关键部件，其顺畅运行离不开合理的润滑。润滑脂能减少滑块与导轨之间的摩擦磨损，降低运行噪音，延长设备使用寿命。掌握正确的润滑脂添加方法，是保证导轨滑块性能的重要环节，需按照规范步骤操作，兼顾细节处理。

　　As a key component in mechanical transmission, the smooth operation of the guide rail slider relies on proper lubrication. Lubricating grease can reduce the friction and wear between the slider and the guide rail, lower the operating noise, and extend the service life of the equipment. Mastering the correct method of adding lubricating grease is an important step in ensuring the performance of the guide rail slider. It is necessary to follow the standardized steps and pay attention to details.

　　添加前的准备工作直接影响润滑效果。要选择适配的润滑脂，不同型号的导轨滑块对润滑脂的粘度、耐温性要求不同，需根据设备说明书的型号选购，避免因型号不符导致润滑不良或部件损坏。例如，高速运行的导轨滑块应选用低粘度、流动性好的润滑脂，而在高温环境下工作的部件则需耐温性强的润滑脂。其次，需清洁导轨和滑块的润滑部位，用干净的抹布或毛刷表面的油污、灰尘和金属碎屑，若油污较厚，可先用煤油擦拭，待完全干燥后再进行添加，防止杂质混入润滑脂，加剧部件磨损。同时，准备好专用的加注工具，如黄油枪、注脂嘴等，确保工具清洁无杂质，避免污染润滑脂。

　　The preparation work before adding directly affects the lubrication effect. Firstly, it is necessary to choose the appropriate lubricating grease. Different models of guide rail sliders have different requirements for the viscosity and temperature resistance of the lubricating grease. It is necessary to select the recommended model according to the equipment manual to avoid poor lubrication or component damage caused by inconsistent models. For example, lubricating grease with low viscosity and good fluidity should be selected for high-speed running guide rail sliders, while lubricating grease with strong temperature resistance is required for components working in high-temperature environments. Secondly, it is necessary to clean the lubrication parts of the guide rail and slider, using a clean cloth or brush to remove surface oil, dust, and metal debris. If the oil is thick, it can be wiped with kerosene first, and then added after it is completely dry to prevent impurities from mixing into the lubricating grease and exacerbating component wear. At the same time, prepare specialized filling tools such as a grease gun, grease nozzle, etc., to ensure that the tools are clean and free of impurities, and to avoid contaminating the lubricating grease.

　　判断添加时机是合理润滑的前提。导轨滑块的润滑周期需根据使用频率和工作环境确定，一般情况下，每天连续运行 8 小时的设备，建议每两周添加一次润滑脂；运行频率较低的设备，可每月添加一次。当发现滑块运行时有异响、卡顿，或观察到导轨表面润滑脂明显减少、干涸时，需及时补充。添加前需检查润滑脂的状态，若润滑脂出现硬化、结块或变色，说明已变质，需先将旧脂干净，再添加新脂，避免新旧脂混合影响润滑效果。

　　Judging the timing of addition is a prerequisite for reasonable lubrication. The lubrication cycle of the guide rail slider needs to be determined according to the frequency of use and working environment. Generally, for equipment that runs continuously for 8 hours a day, it is recommended to add lubricating grease every two weeks; Devices with lower operating frequencies can be added once a month. When there is abnormal noise or jamming during the operation of the slider, or when the lubricating grease on the surface of the guide rail is significantly reduced or dried up, it is necessary to replenish it in a timely manner. Before adding, it is necessary to check the condition of the lubricating grease. If the grease hardens, clumps or changes color, it indicates that it has deteriorated. The old grease should be removed first, and then new grease should be added to avoid mixing old and new grease and affecting the lubrication effect.

　　具体添加过程需注重均匀与适量。对于带有注脂嘴的导轨滑块，将润滑脂装入黄油枪，对准注脂嘴缓慢挤压，直有少量润滑脂从滑块两端溢出，表明内部已充满润滑脂。添加时需控制力度，避免因压力过大导致润滑脂飞溅或部件变形。无注脂嘴的滑块，可直接将润滑脂涂抹在导轨的滑动面上，涂抹厚度以均匀覆盖表面为宜（约 0.5-1 毫米），同时在滑块的密封件内侧也需涂抹少量润滑脂，增强密封性，防止灰尘进入。对于多滑块组合的导轨，每个滑块都需单独添加，确保润滑均匀，避免因个别滑块润滑不足导致整体运行不畅。添加过程中，可手动推动滑块往复移动几次，使润滑脂在滑块内部充分分布，减少局部缺脂现象。

　　The specific addition process should pay attention to uniformity and moderation. For the guide rail slider with grease injection nozzle, insert lubricating grease into the grease gun, align with the grease injection nozzle and slowly squeeze until a small amount of lubricating grease overflows from both ends of the slider, indicating that the interior is filled with lubricating grease. When adding, the force should be controlled to avoid splashing of lubricating grease or deformation of components due to excessive pressure. For the slider without a grease nozzle, lubricating grease can be directly applied to the sliding surface of the guide rail, with a suitable thickness to evenly cover the surface (about 0.5-1 mm). At the same time, a small amount of lubricating grease should be applied to the inside of the sealing element of the slider to enhance sealing and prevent dust from entering. For guide rails with multiple slider combinations, each slider needs to be added separately to ensure uniform lubrication and avoid overall poor operation caused by insufficient lubrication of individual sliders. During the addition process, the slider can be manually pushed back and forth several times to fully distribute the lubricating grease inside the slider and reduce local grease shortage.

　　添加后的检查与维护能保障润滑效果的持久性。添加完成后，启动设备空运行 1-2 分钟，观察滑块运行是否顺畅，有无异常噪音，若发现异常需立即停机检查，排除润滑脂过多或部件卡滞的问题。运行后再次清洁导轨表面溢出的多余润滑脂，防止吸附灰尘形成油泥。定期检查润滑脂的消耗情况，结合设备运行状态调整添加周期，在粉尘较多、湿度较大的环境中，需缩短润滑周期，加强防护措施，如加装防尘罩，减少杂质对润滑部位的污染。长期停用的设备，在启用前需重新添加润滑脂，避免因润滑脂干涸导致启动时部件磨损。

　　The inspection and maintenance after addition can ensure the durability of the lubrication effect. After adding, start the device and run it idle for 1-2 minutes to observe if the slider runs smoothly and if there are any abnormal noises. If any abnormalities are found, stop the machine immediately for inspection to eliminate problems such as excessive lubricating grease or component jamming. After operation, clean the excess lubricating grease that overflows from the surface of the guide rail again to prevent the adsorption of dust and the formation of oil sludge. Regularly check the consumption of lubricating grease, adjust the addition cycle according to the operating status of the equipment. In environments with high dust and humidity, it is necessary to shorten the lubrication cycle and strengthen protective measures, such as installing dust covers to reduce the pollution of impurities on the lubrication parts. Equipment that has been out of use for a long time needs to be refilled with lubricating grease before use to avoid component wear during startup due to dry lubricating grease.
