南通INA轴承配置安全性的规范

（1）INA可调式滚子轴承
(1) INA adjustable roller bearing
南通INA轴承的配置与早期轧机不同。当时，两套自动调心滚子轴承主要安装在同一辊颈上。该配置基本满足当时的生产条件，轧制速度可达600 rpm。然而，随着速度的提高，其缺点更为**：F轴承寿命短、消耗量大、成品精度低、轧辊磨损严重、轧辊轴向运动大等。
The configuration of the Nantong INA bearing is different from that of the early rolling mill. At that time, two sets of self aligning roller bearings were mainly installed on the same roll neck. The configuration basically meets the production conditions at that time and the rolling speed can reach 600 rpm. However, with the increase of speed, its disadvantages are more prominent: short life of F bearing, large consumption, low precision of finished product, serious wear of roll and large axial movement of roll.
（2）INA轴承-四柱滚子+推力轴
(2) INA bearing - four - column roller + thrust axis
南通INA圆柱滚子轴承内径与辊颈紧密匹配，承受径向力。它具有承载能力大、极限速度高、精度高、内外环可分离、互换性好、加工容易、生产成本低、安装拆卸方便等优点。推力轴承承受轴向力，混凝土结构类型可基于轧机。选择的特点。重载、低速，采用南通INA轴承推力滚子轴承，轴向间隙较小，能承受推力负荷。在轧制速度高的情况下，南通INA角接触球轴承不仅具有高速极限，而且可以控制轴向间隙。滚子轴向受轴向导向，能承受一般轴向载荷。这种轴承结构不仅使用寿命长，可靠性高，而且具有精度高、易于控制轧制产品等诸多优点。目前应用较广泛，主要用于线材轧机、板轧机、箔轧机、冷轧机、热轧机等。
The inner diameter of Nantong INA cylindrical roller bearing is closely matched with the neck of the roller, and it bears radial force. It has the advantages of large bearing capacity, high limit speed, high precision, separation of inner and outer ring, good interchangeability, easy processing, low production cost, convenient installation and disassembly and so on. The thrust bearing is subjected to axial force, and the type of concrete structure can be based on rolling mill. The characteristics of the choice. Heavy load and low speed, Nantong INA bearing thrust roller bearing has smaller axial clearance and can withstand thrust load. Under the condition of high rolling speed, the INA angular contact ball bearing in Nantong not only has high speed limit, but also can control axial clearance. Roller is axially oriented and can withstand general axial loads. This bearing structure has not only long service life, high reliability, but also high precision, easy control of rolling products and many other advantages. At present, it is the most widely used, mainly used in wire mill, plate mill, foil rolling mill, cold rolling mill, hot rolling mill and so on.
（3）INA轴承四列圆锥滚子
(3) four row tapered roller of INA bearing
圆锥滚子南通INA轴承既可承受径向力，又可承受轴向力，不需要配置推力轴承。因此，主机更紧凑。圆锥滚子轴承的内径与滚子的颈部松配合。安装和拆卸非常方便，但有时由于松木的匹配会引起滑动蠕变，因此内径经常用螺旋形油槽加工。这种结构目前仍广泛应用，如轧辊、小方坯米尔斯、钢梁米尔斯等四辊热轧米尔斯和冷轧米尔斯。
Tapered roller Nantong INA bearing can bear both radial force and axial force, and no thrust bearing is required. As a result, the host is more compact. The inner diameter of tapered roller bearings is matched with the neck of rollers. Installation and disassembly are very convenient, but sometimes due to the matching of pine will cause sliding creep, so the inner diameter is often processed with spiral oil groove. This structure is still widely used, such as roll, billet Mills, steel beam Mills and so on four roll hot rolling Mills and cold rolling Mills.
