Reasons for premature aging of linear guide rail: we know that any mechanical product has a certain service life, so we need to find out the problems as early as possible and maintain the service life of the product! Next, the guide screw manufacturer will elaborate the reasons for premature aging of linear guide rail and how we should deal with these problems for you. Through more than ten years of experience, we can judge the linear guide rail Causes of premature aging: too tight fitting, poor lubrication, misaligned installation, strong vibration, material fatigue, pollution and corrosion, etc.

　　1、直線導軌帶得太緊:導軌被迫將內圈放入軸頸，輕則會造成滾道圈軌道底部嚴重磨損，重則在滑塊內側，外圈與滾珠會有裂紋或剝落。原因:球與滑塊之間的間隙過小，轉矩增大，摩擦增大，軸承工作溫度過高，使軸承的磨損和疲勞加劇而失效。解決方案:恢復導軌徑向間隙，減少干擾。

　　1. The linear guide rail is too tight: the guide rail is forced to put the inner ring into the journal. If it is light, it will cause serious wear at the bottom of the track of the raceway ring. If it is heavy, it will be inside the slider. The outer ring and the ball will crack or peel off. Causes: the clearance between the ball and the slider is too small, the torque is increased, the friction is increased, and the working temperature of the bearing is too high, which makes the wear and fatigue of the bearing increase and the bearing fails. Solution: restore radial clearance of guide rail and reduce interference.

　　二、直線導軌潤滑:其原因是潤滑脂嚴重缺乏或潤滑脂干燥老化。由于電機高速運行時產生的摩擦熱，軸承溫度過高而氧化變色，軸承的球、保持架、內圈及其軸頸等性能呈褐色或藍色。解決方案:根據電機的運行時間、環境溫度、負載狀態、油脂質量等4個因素，確定其換油及換油時間。一般電機運行6000~10000h后應補充一次。10000~20000h運行中換油一次，2根及4根以上電機換油量為軸承室容積的1/2~2/3，鋰基潤滑脂(代號zl-2)應使用。

　　2、 Linear guide rail lubrication: the reason is serious lack of grease or aging of grease. Due to the friction heat generated by the high-speed operation of the motor, the bearing temperature is too high and the oxidation discoloration occurs. The ball, cage, inner ring and Journal of the bearing are brown or blue. Solution: according to the four factors of motor operation time, environment temperature, load state and grease quality, determine the oil change and oil change time. Generally, the motor shall be supplemented once after running for 6000-10000h. Oil change shall be carried out once in 10000-20000 h operation. The oil change capacity of two or more motors is 1 / 2-2 / 3 of the bearing chamber volume. High quality lithium-based grease (code ZL-2) shall be used.

　　3.直線導軌振動強:電機核心失效時，軸承振動強。其原因是:鐵芯受熱變形;電動機軸承老化;轉軸彎曲變形大;端蓋止動處的緊固螺栓因振動松動;地基薄弱使軸承振動。解決方案:鐵芯小車，用有機硅清漆1052浸漬硅鋼片表面并打開縫隙;更換同類型軸承;出口轉子鐵芯對準軸彎曲部分;采用180°對稱法;上緊端蓋止動螺栓;加固基礎，擰緊地腳螺栓。

　　3. Strong vibration of linear guide rail: when the motor core fails, the bearing vibration is strong. The reasons are: the iron core is deformed by heat; the motor bearing is aged; the shaft is bent and deformed greatly; the fastening bolts at the end cover stop are loose due to vibration; the bearing vibrates due to the weak foundation. Solution: iron core trolley, impregnate the silicon steel sheet surface with silicone varnish 1052 and open the gap; replace the same type of bearing; align the iron core of the outlet rotor with the bending part of the shaft; use the 180 ° symmetry method; tighten the end cover stop bolt; strengthen the foundation and tighten the foundation bolt.

　　四、直線導軌污染腐蝕:此時，導軌與球體表面出現紅色、褐色斑點腐蝕，與新的軸承噪音相比。解決方案:裝配軸承應保持環境、工具和操作的清潔;徹底清潔軸承;更換高質量的鋰潤滑脂

　　4、 Pollution and corrosion of linear guide rail: at this time, there are red and brown spots on the surface of guide rail and ball, compared with the new bearing noise. Solution: keep environment, tools and operation clean when assembling bearing; clean bearing thoroughly; replace high quality lithium grease

　　直線導軌的作用是導向和支撐。為了保證機床具有較高的加工精度，要求導軌和直線具有較高的導軌精度和良好的運動穩定性。在設備運行過程中，被加工工件的加工過程中會產生大量的腐蝕性粉塵和煙塵。基于這些煙霧和灰塵沉積表面的導軌和直線軸大量很長一段時間,它有一個偉大的對設備的加工精度的影響,并將表面形成腐蝕斑點的直線軸導軌,縮短設備的使用壽命。為了使機床工作正常穩定，保證產品的加工質量，要認真做好導軌、直軸的日常保養。

　　The function of linear guide is to guide and support. In order to ensure the high machining accuracy of the machine tool, it is required that the guide rail and the straight line have high precision and good motion stability. In the process of equipment operation, a large number of corrosive dust and dust will be produced during the processing of the processed workpiece. Based on these smoke and dust deposition surface of the guide rail and linear axis for a long time, it has a great impact on the machining accuracy of the equipment, and will form corrosion spots on the surface of the linear axis guide rail, shorten the service life of the equipment. In order to ensure the normal and stable operation of the machine tool and the processing quality of the products, the daily maintenance of the guide rail and the straight shaft should be done well.
