与INA轴承套圈不同，超大型轴承属于单机、单人和单件加工。它们是非常随机的，很容易导致尺寸或形状公差过大，例如车削后磨损小、热处理变形过大、收缩过大和收缩不均匀、渗碳垫损坏和处理碰撞损坏。如果按正常工艺加工，这些零件将成为不合格品。经分析，部分不合格品可采取措施予以保存。
Unlike INA bearing rings, super-large bearings belong to single machine, single person and single piece processing. They are very random and can easily lead to excessive tolerances of size or shape, such as ***all wear after turning, excessive heat treatment deformation, excessive shrinkage and uneven shrinkage, carburizing pad damage and handling collision damage. If processed according to normal process, these parts will become unqualified products. After analysis, some unqualified products can be preserved by measures.
首先，精缺测量INA轴承套圈每种缺点（不对称型）的尺寸，计算出***小磨削量（成品尺寸偏差时的磨削量）m。然后，运动部件的中xin（沿增加缺点处磨削量的方向），***大偏差为m/2，即缺点处磨削量的相对增加，主要是磨削。
Firstly, the dimension of each disadvantage (asymmetric type) of INA bearing rings is measured, and the ***all grinding quantity of *** (grinding quantity when finished product size deviation) m is calculated. Then, in the direction of increasing the grinding quantity at the disadvantage, the large deviation of *** is m/2, that is, the relative increase of the grinding quantity at the disadvantage is mainly grinding.
轴承套圈磨削的设计准则是内径或外径，即磨削滚道前先磨削内（外）径。也就是说，磨削内径时，内滚道缺点的磨削量先相对增加，再强调磨削缺点，以节约废品。当m1大于或等于m时，不能失去正常磨削。根据情况，INA轴承套圈Di1.1节所述的方法可用于保存。
The design criterion of bearing ring grinding is inner diameter or outer diameter, i. e. grinding inner (outer) diameter before grinding raceway. That is to say, when grinding inner diameter, the grinding quantity of inner raceway shortcomings first increases relatively, then emphasizes the grinding shortcomings, in order to s***e waste products. When M1 is greater than or equal to m, normal grinding cannot be lost. Depending on the situation, the method described in section Di 1.1 of INA bearing rings can be used for preservation.
一般可分为多偏压磨削、测量、偏差调整和再磨削。缺点磨削后，椭圆可以用普通的磨削方法进行修正。这种方法效率低下，要求操作者具有较高的技术水平。然而，在单机和单件生产中，这种方法具有很高的成功率，不会耽误生产进度。经过几年的实践，效果很好。
Generally, it can be divided into multi-bias grinding, measurement, deviation adjustment and re-grinding. After the defect grinding, ellipse can be corrected by ordinary grinding method. This method is inefficient and requires the operator to h***e a high technical level. However, in single machine and single piece production, this method has a high success rate and will not delay the production progress. After several years of practice, the effect is very good.
对于尺寸公差超过设计标准的轴承零件，INA轴承套圈可采用化学沉积法进行保存。化学沉积的原理是通过各种化学原料之间的化学反应，在零件表面均匀地生成一定厚度的金属涂层。额外的回火确保金属层的硬度和机械性能与原始零件相同。化学沉积只能在不改变形状公差的情况下增加零件的尺寸。因此，对于尺寸公差过大的零件，化学沉积是一种有笑的补救措施。目前，单侧沉积的***大厚度可达0.1毫米左右。
For bearing parts whose dimension tolerance exceeds the design standard, INA bearing rings can be preserved by chemical deposition method. The principle of chemical deposition is to uniformly generate a certain thickness of metal coating on the surface of parts through chemical reacti*** between various chemical raw materials. Additional tempering ensures that the hardness and mechanical properties of the metal layer are the same as those of the original parts. Chemical deposition can only increase the size of parts without changing the shape tolerance. Therefore, chemical deposition is a laughable remedy for parts with excessive size tolerance. At present, the thickness of *** deposited unilaterally can reach about 0.1 mm.
INA轴承套圈淬火马氏体和残余奥氏体是不稳定***。在回火过程中，钢的体积因马氏体的fen解而收缩，而钢的体积因残余奥氏体的fen解而膨胀。
The quenched martensite and retained austenite of INA bearing rings are unstable structures. During tempering, the volume of steel shrinks due to the Fen solution of martensite, while the volume of steel expands due to the Fen solution of retained austenite.
该方法对残余奥氏体含量高的厚、重工件，特别是对调心滚子轴承有显著影响。在实际生产中，针对不同规格、尺寸和厚度的零件，制定了不同的回火工艺。在保证INA轴承套圈硬度和变形的前提下，对结构进行quan面改造，使其产生较大的膨胀，相应地增加磨损，从而节约废品。
This method has a significant effect on thick and he***y workpieces with high retained austenite content, especially on self-aligning roller bearings. In actual production, different tempering processes are formulated for parts of different specificati***, sizes and thicknesses. On the premise of guaranteeing the hardness and deformation of INA bearing rings, the Quan surface of the structure is reformed to produce larger expansion and correspondingly increase wear and tear, thus s***ing waste products.
