徐州SKF軸承618/900滾子系列的隨機裝配性

發布時間:2019-01-03 08:31:11        

在圓錐滾子徐州SKF軸承中,滾子和內外滾道都是圓錐表面。在制造過程中,由于錐環的直徑、角度和長度的偏差,錐接頭內外的接觸會影響到底距。在圓錐滾子軸承的裝配過程中,滾動體的加工質量對軸承的裝配質量有著非常重要的影響。目前,在國內軸承零件加工中,軋輥的質量控制越來越受到重視。這為圓錐滾子軸承裝配過程中隨機裝配方法的發展和廣泛應用創造了條件。

In the SKF bearing of tapered roller in Xuzhou, both the roller and the inner and outer raceways are tapered surfaces. In the manufacturing process, due to the deviation of the diameter, angle and length of the cone ring, the contact between the inside and outside of the cone joint will affect the base distance. In the assembly process of tapered roller bearings, the processing quality of rolling elements has a very important impact on the assembly quality of bearings. At present, in the domestic bearing parts processing, the quality control of rolls has been paid more and more attention. This has created conditi*** for the development and wide application of random assembly method in the assembly process of tapered roller bearings.

所謂隨機裝配法,是指在生產現場按**終加工順序將徐州SKF軸承分成一組n個顆粒,將每組滾子放入塑料管、塑料袋、盒子等特殊包裝中,或直接用塑料籠成型零件。通過觸摸軸承上的鋼印,可以更快、更準確地識別軸承。這種圖章不需要用手觸摸,但成品組裝時,只要輕輕觸摸指甲上的圖章,就可以感覺到圖章的存在。然后將每組滾輪安裝在一組軸承中。與選擇性裝配相比,隨機裝配具有許多優點和較好的經濟效益。例如,簡化了工藝流程,沒有對**終加工桶進行分類,節省了人力物力。

The so-called random assembly method refers to dividing Xuzhou SKF bearings into a group of N particles according to the sequence of ** final processing at the production site, and putting each group of rollers into special packaging such as plastic pipes, plastic bags, boxes, or directly forming parts with plastic cages. By touching the steel stamp on the bearing, the bearing can be recognized more quickly and accurately. This kind of stamp does not need to be touched by hand, but when the finished product is assembled, the existence of the stamp can be felt by touching the stamp on the nail lightly. Each set of rollers is then mounted in a set of bearings. Compared with selective assembly, random assembly has many advantages and better economic benefits. For example, it simplifies the process flow, does not classify the ** final processing barrel, and s***es manpower and material resources.

圓錐滾子徐州SKF軸承傳統的裝配方法是將加工好的滾子混合在一起,然后通過分級機或手動尺寸分組將其裝配成保持架。軸承具有額定負荷高、噪音低、大大降低維護成本、延長機器運行時間等優點。分離圓錐滾子時,分離器只能測量徐州SKF軸承一個點,但不能測量滾子的角度;不能避免因產品不干凈而導致***精度不準確,降低了分選精度;同時也不能避免產品堵塞、磕碰、生銹的發生。目前我國圓錐滾子分離機的設計制造技術還不成熟,圓錐滾子的尺寸分組嚴重影響軸承的裝配質量。

The traditional assembly method of tapered roller Xuzhou SKF bearings is to mix the processed rollers together, and then assemble them into cages by classifier or manual size grouping. Bearing has the advantages of high rated load, low noise, greatly reducing maintenance costs and prolonging machine operation time. When separating tapered rollers, the separator can only measure one point of Xuzhou SKF bearing, but can not measure the angle of the rollers; it can not ***oid inaccurate positioning accuracy caused by unclean products, which reduces the sorting accuracy; at the same time, it can not ***oid the occurrence of product clogging, bumping and rusting. At present, the design and manufacture technology of tapered roller separator in our country is not mature, and the dimension grouping of tapered roller seriously affects the assembly quality of bearings.

在圓錐滾子徐州SKF軸承裝配計算中,理論分析和數值算例表明,一般軸承配合零件的尺寸偏差可以滿足成品軸承寬度偏差的要求。

In the assembling calculation of SKF bearing with tapered roller in Xuzhou, theoretical analysis and numerical examples show that the dimension deviation of general bearing matching parts can meet the requirement of width deviation of finished bearing.
