你知道怎样预防直线导轨的防尘与磨损吗?

来源:http://www.jngongrun.com/ 日期:2018-12-07 发布人:admin

直线导轨要想得到很好的加工精度保持它的性能特点,防尘是非常关键的一个措施。对于这种精度要求极高的部件来说,任何的一点灰尘和杂质都是不好的,它会破坏整个直线运动系统,进而缩短使用寿命。那么,应该如何做好直线导轨的防尘工作呢?

Dust-proof is a key measure for linear guide to obtain good machining accuracy and maintain its performance characteristics. For such components with high precision requirements, any dust and impurities are not good. It will destroy the whole linear motion system and shorten the service life. Then, how should we do well in the dust prevention work of linear guides?
首先,直线导轨系统里面离不开密封件的使用,因为它有不少的缝隙比较容易让灰尘和杂质钻空子,所以要想让整个系统内部达到一个密封的状态就必须要用密封垫片将这些缝隙给堵上。
Firstly, the use of seals is indispensable to the linear guideway system, because it has many cracks which are easy to let dust and impurities drill holes, so in order to make the whole system to achieve a sealed state, it is necessary to use sealing gaskets to plug these cracks.
但是对于密封垫片的使用是有一些讲究的,它不是普通的材料就可以,相反,用于制作直线导轨密封垫片的材料必须是专业的橡胶材料,然后制作成清洁环。
But for the use of sealing gaskets, there are some fastidious, it is not ordinary material can, on the contrary, used to make linear guide sealing gaskets material must be professional rubber material, and then made into a clean ring.
橡胶垫片较大的好处就在于它具有非常强的韧性,弹性系数非常高,虽然它的制作成本比普通的塑料垫片高了很多,但是它作为垫片使用的时候可以不留半点缝隙。
The greatest advantage of rubber gasket is that it has very strong toughness and high elastic coefficient. Although its production cost is much higher than that of ordinary plastic gasket, it can be used as gasket without leaving half a gap.
其次,防尘罩的使用对防尘也有很好的效果,现在使用的防尘罩有专门针对恶劣环境和普通的工作环境两种。在恶劣环境下使用的防尘罩柔软性是非常好的,它可以自由的伸缩,这样就能应对不同的机床结构。还有一种是专业防尘器,它主要是防止灰尘接近直线导轨。
Secondly, the use of dust-proof cover also has a good effect on dust-proof. The dust-proof cover used now has two kinds of special for harsh environment and ordinary working environment. The dustproof cover used in harsh environment is very flexible, it can be flexible freely, so that it can cope with different machine tool structures. There is also a professional dustproof device, which mainly prevents dust from approaching linear guides.
较后,如果需要对直线导轨的滚珠丝杆提供防尘保护的话,还可以使用大型的伸缩防尘罩。
Finally, if it is necessary to provide dust-proof protection for ball screw of linear guideway, large-scale retractable dust-proof cover can also be used.
 
 
直线导轨的磨损
Wear of linear guides
直线导轨发生磨损,将会导致导轨失效,必须更换新的直线导轨,否则将会严重影响到机械设备的生产效率,更有甚者会造成设备的损坏。所以我们在日常的工作中,应当仔细分析直线导轨产生磨损的各种原因,这样才能找到针对直线导轨的磨损解决方案。
The wear and tear of linear guides will lead to the failure of the guides. It is necessary to replace the new linear guides. Otherwise, it will seriously affect the production efficiency of mechanical equipment, or even cause damage to the equipment. Therefore, in our daily work, we should carefully analyze the causes of wear and tear of linear guides, so as to find a solution for wear and tear of linear guides.
1、当有异物进入到了密封不严的直线导轨内部后,将会与润滑油混合在一起,从而造成滑块内部沟槽堵塞,或者直接对直线导轨内部造成损伤。
1. When a foreign body enters the improperly sealed linear guide, it will be mixed with lubricating oil, which will result in the blockage of the grooves in the slider, or directly cause damage to the internal of the linear guide.
2、如果润滑油里面的杂质没有过滤干净,有杂质混入导轨内部,或者润滑的方式不良、选用的润滑剂不正确或变质都会造成直线导轨的磨损。
2. If the impurities in the lubricating oil are not filtered, impurities are mixed into the guide rail, or the lubrication method is not good, the selected lubricant is incorrect or deteriorated, it will cause the wear and tear of the linear guide rail.
3、直线导轨使用时因为温度变化所产生的冷凝水或是润滑剂中添加剂的腐蚀性物质也会造成导轨滑块的锈蚀,从而造成磨损。
3. Condensate water or corrosive substances of additives in lubricants caused by temperature change will also cause the rust of slider of linear guideway, which will cause wear and tear.
以上这些异常将会引起直线导轨工作表面的粗糙和游隙的增加,较终导致导轨的失效。由此可见只要是金属零件,它的正常磨损是不可避免的,而且正常磨损是均匀并且缓慢的进行的,它的磨损程度以及磨损的时间我们也可以按照规律进行预料。
These abnormalities will cause the roughness of the working surface and the increase of the clearance of the linear guide, and eventually lead to the failure of the guide. Therefore, as long as it is a metal part, its normal wear is inevitable, and the normal wear is uniform and slow, its wear degree and wear time can also be predicted according to the law.
