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(dǎo)軌帶得太緊:導(dǎo)軌被迫將內(nèi)圈放入軸頸，輕則會(huì)造成滾道圈軌道底部嚴(yán)重磨損，重則在滑塊內(nèi)側(cè)，外圈與滾珠會(huì)有裂紋或剝落。原因:球與滑塊之間的間隙過(guò)小，轉(zhuǎn)矩增大，摩擦增大，軸承工作溫度過(guò)高，使軸承的磨損和疲勞加劇而失效。解決方案:恢復(fù)導(dǎo)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(dǎo)軌潤(rùn)滑:其原因是潤(rùn)滑脂嚴(yán)重缺乏或潤(rùn)滑脂干燥老化。由于電機(jī)高速運(yùn)行時(shí)產(chǎn)生的摩擦熱，軸承溫度過(guò)高而氧化變色，軸承的球、保持架、內(nèi)圈及其軸頸等性能呈褐色或藍(lán)色。解決方案:根據(jù)電機(jī)的運(yùn)行時(shí)間、環(huán)境溫度、負(fù)載狀態(tài)、油脂質(zhì)量等4個(gè)因素，確定其換油及換油時(shí)間。一般電機(jī)運(yùn)行6000~10000h后應(yīng)補(bǔ)充一次。10000~20000h運(yùn)行中換油一次，2根及4根以上電機(jī)換油量為軸承室容積的1/2~2/3，鋰基潤(rùn)滑脂(代號(hào)zl-2)應(yīng)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(dǎo)軌振動(dòng)強(qiáng):電機(jī)核心失效時(shí)，軸承振動(dòng)強(qiáng)。其原因是:鐵芯受熱變形;電動(dòng)機(jī)軸承老化;轉(zhuǎn)軸彎曲變形大;端蓋止動(dòng)處的緊固螺栓因振動(dòng)松動(dòng);地基薄弱使軸承振動(dòng)。解決方案:鐵芯小車，用有機(jī)硅清漆1052浸漬硅鋼片表面并打開(kāi)縫隙;更換同類型軸承;出口轉(zhuǎn)子鐵芯對(duì)準(zhǔn)軸彎曲部分;采用180°對(duì)稱法;上緊端蓋止動(dòng)螺栓;加固基礎(chǔ)，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(dǎo)軌污染腐蝕:此時(shí)，導(dǎo)軌與球體表面出現(xiàn)紅色、褐色斑點(diǎn)腐蝕，與新的軸承噪音相比。解決方案:裝配軸承應(yīng)保持環(huán)境、工具和操作的清潔;徹底清潔軸承;更換高質(zhì)量的鋰潤(rùn)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(dǎo)軌的作用是導(dǎo)向和支撐。為了保證機(jī)床具有較高的加工精度，要求導(dǎo)軌和直線具有較高的導(dǎo)軌精度和良好的運(yùn)動(dòng)穩(wěn)定性。在設(shè)備運(yùn)行過(guò)程中，被加工工件的加工過(guò)程中會(huì)產(chǎn)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(dǎo)軌和直線軸大量很長(zhǎng)一段時(shí)間,它有一個(gè)偉大的對(duì)設(shè)備的加工精度的影響,并將表面形成腐蝕斑點(diǎn)的直線軸導(dǎo)軌,縮短設(shè)備的使用壽命。為了使機(jī)床工作正常穩(wěn)定，保證產(chǎn)品的加工質(zhì)量，要認(rèn)真做好導(dǎo)軌、直軸的日常保養(yǎng)。

　　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.
