In order to make the bearing reach the better ideal life value, what grade of grease to fill and the amount of grease to fill are scientific schemes obtained through countless practical experiments. It is generally believed that the grease consumption life is equivalent to the bearing life. In addition, the design of the sealing cover, the distance from the inner ring, or contact, or non-contact, or labyrinth are well designed. When refueling, the disassembly of the seal cover is bound to affect its effect, and then affect the service life of the bearing.

軸承密封方法有哪些？

What are the sealing methods of bearings?

滾動(dòng)軸承的密封方法可分為接觸式密封及非接觸式兩類。所謂軸承自帶密封就是把軸承自身制作成具有密封功能設(shè)備的。如軸承帶防塵蓋、密封圈等。這種密封占用空間很。所謂軸承外加密封功能設(shè)備，就是在設(shè)備端蓋等內(nèi)部制作成具有各種功能的密封設(shè)備。

The sealing methods of rolling bearings can be divided into contact sealing and non-contact sealing. The so-called bearing with seal is to make the bearing itself into a sealing function equipment. Such as bearing with dust cover, sealing ring, etc. This seal takes up a lot of space. The so-called bearing external sealing function equipment is to make sealing equipment with various functions inside the end cover of the equipment.

1、接觸式密封有氈圈密封、密封圈密封等。

1. Contact seal has felt ring seal, seal ring seal, etc.

2、非接觸式密封有軸向曲路密封、徑向曲路密封、油溝密封、擋圈密封等。

2. Non contact seals include axial curved seal, radial curved seal, oil groove seal, retaining ring seal, etc.

在此壽命以內(nèi)的軸承，應(yīng)在其任何軸承圈或滾動(dòng)體上發(fā)生初步疲勞損壞（剝落或缺損）。然而無論在實(shí)驗(yàn)室試驗(yàn)或在實(shí)際使用中，都可明顯地看到，在同樣的工作條件下的外觀相同軸承，實(shí)際壽命大不相同。

For bearings within this life span, initial fatigue damage (spalling or defect) should occur on any bearing ring or rolling element. However, no matter in the laboratory test or in the actual use, it can be clearly seen that under the same working conditions, the appearance of the same bearing, the actual life is very different.

此外還有數(shù)種不同定義的軸承“壽命”，其中之一即所謂的“工作壽命”，它表示某一軸承在損壞之前可達(dá)到的實(shí)際壽命是由磨損、損壞通常并非由疲勞所致，而是由磨損、腐蝕、密封損壞等原因造成。

In addition, there are several different definitions of bearing "life", one of which is the so-called "working life", which means that the actual life of a bearing before damage is caused by wear, damage is usually not caused by fatigue, but by wear, corrosion, seal damage and other reasons.

軸承密封圈，一種軸承密封件，尤其是一種滾珠軸承密封圈，滾珠軸承密封圈是在圓環(huán)形的一個(gè)端面上向上延伸著兩個(gè)成圓形的凸起，所述的直徑較小的凸起的內(nèi)徑與滾珠軸承的內(nèi)圈外徑相配合，所述的直徑較大的凸起與滾珠軸承的滾珠圈外徑相配合；所述的密封圈的內(nèi)孔徑不小于滾珠軸承內(nèi)圈的內(nèi)孔徑。具有防止油脂起火、避免經(jīng)常加油且結(jié)構(gòu)簡(jiǎn)單等特點(diǎn)。在軸承上被廣泛使用。

The invention relates to a bearing sealing ring, in particular to a ball bearing sealing ring. The ball bearing sealing ring has two round protrusions extending upward on one end face of a ring shape. The inner diameter of the smaller protrusion is matched with the outer diameter of the inner ring of the ball bearing, and the larger protrusion is matched with the outer diameter of the ball ring of the ball bearing The inner diameter of the inner ring is not less than that of the inner ring of the ball bearing. The utility model has the advantages of preventing oil from ignition, avoiding frequent oiling and simple structure. It is widely used in bearings.
