徐州SKF轴承618/900滚子系列的随机装配性

在圆锥滚子徐州SKF轴承中，滚子和内外滚道都是圆锥表面。在制造过程中，由于锥环的直径、角度和长度的偏差，锥接头内外的接触会影响到底距。在圆锥滚子轴承的装配过程中，滚动体的加工质量对轴承的装配质量有着非常重要的影响。目前，在国内轴承零件加工中，轧辊的质量控制越来越受到重视。这为圆锥滚子轴承装配过程中随机装配方法的发展和广泛应用创造了条件。

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.

所谓随机装配法，是指在生产现场按**终加工顺序将徐州SKF轴承分成一组n个颗粒，将每组滚子放入塑料管、塑料袋、盒子等特殊包装中，或直接用塑料笼成型零件。通过触摸轴承上的钢印，可以更快、更准确地识别轴承。这种图章不需要用手触摸，但成品组装时，只要轻轻触摸指甲上的图章，就可以感觉到图章的存在。然后将每组滚轮安装在一组轴承中。与选择性装配相比，随机装配具有许多优点和较好的经济效益。例如，简化了工艺流程，没有对**终加工桶进行分类，节省了人力物力。

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.

圆锥滚子徐州SKF轴承传统的装配方法是将加工好的滚子混合在一起，然后通过分级机或手动尺寸分组将其装配成保持架。轴承具有额定负荷高、噪音低、大大降低维护成本、延长机器运行时间等优点。分离圆锥滚子时，分离器只能测量徐州SKF轴承一个点，但不能测量滚子的角度；不能避免因产品不干净而导致***精度不准确，降低了分选精度；同时也不能避免产品堵塞、磕碰、生锈的发生。目前我国圆锥滚子分离机的设计制造技术还不成熟，圆锥滚子的尺寸分组严重影响轴承的装配质量。

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.

在圆锥滚子徐州SKF轴承装配计算中，理论分析和数值算例表明，一般轴承配合零件的尺寸偏差可以满足成品轴承宽度偏差的要求。

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.
