江苏SKF轴承的环境气氛（腐蚀性、清洁性和润滑性）通常由轴向、径向和轴向两个轴承支承。在这一点上，侧轴承称为固定侧轴承，它承受两个径向和轴向载荷，以及固定轴与轴承箱之间的相对轴向位移。使用。
The environmental atmosphere (corrosiveness, cleanliness and lubricity) of SKF bearings in Jiangsu is usually supported by two bearings, axial, radial and axial. At this point, the side bearing is called the fixed side bearing, which bears two radial and axial loads, and the relative axial displacement between the fixed shaft and the bearing box. Use.
另一侧称为自由侧，仅承受径向载荷，而江苏SKF轴承的轴向可相对移动，以解决由于温度变化导致的膨胀部分与轴轴承之间的间隔误差。
The other side is called the free side, only bearing the radial load, and the axial direction of the Jiangsu SKF bearing can be moved relatively to solve the interval error between the expansion part and the shaft bearing due to the temperature change.
对于固定侧滚动轴承，有必要选择江苏滚动轴承江苏SKF轴承在滚动运动（如圆柱滚子轴承）或装配表面上的轴承运动（如球轴承滚珠轴承）的轴向运动。在相对短的轴上，轴向支撑条件，例如向心推力球轴承，在固定方向和单向自由侧使用。
For a fixed side rolling bearing, it is necessary to choose the axial motion of the Jiangsu rolling bearing Jiangsu SKF bearing on the rolling movement (such as cylindrical roller bearings) or the bearing motion on the assembly surface (such as ball bearing ball bearings). On a relatively short axis, axial support conditi***, such as centripetal thrust ball bearings, are used in fixed direction and one-way free side.
江苏SKF轴承材料通常由碳钢和合金钢制成，锻件通常是锻件。优质中碳钢因其低成本、高综合力学性能而被广泛应用，其中45号钢应用***为广泛。
Jiangsu SKF bearing materials are usually made of carbon steel and alloy steel, and forgings are usually forgings. High quality medium carbon steel is widely used because of its low cost and high comprehensive mechanical properties, of which No. 45 steel is the most widely used.
为了提高江苏SKF轴承的力学性能，应进行淬火、回火或正火。合金钢具有较高的力学性能，但价格昂贵，主要用于轴的特殊要求。
In order to improve the mechanical properties of SKF bearing in Jiangsu, quenching, tempering or normalizing should be carried out. Alloy steel has high mechanical properties, but it is expensive, and is mainly used for special requirements of shaft.
例如，大型电机转子江苏SKF轴承等轴工件在高温、高速、重载条件下必须具有良好的高温力学性能。通常采用40Cr、35SiMn、42SiMn等合金结构钢。
For example, large motor rotor Jiangsu SKF bearing equiaxed workpiece must h***e good high temperature mechanical properties under high temperature, high speed and he***y load conditi***. 40Cr, 35SiMn, 42SiMn and other alloy structural steels are usually used.
值得注意的是，江苏SKF轴承钢的类型和热处理对轴的弹性模量影响不大。如果使用合金钢或热处理来增加轴的刚度，它就会失效。此外，合金钢对应力集中更敏感，应从结构上减少应力集中和表面粗糙度。
It is worth noting that the type and heat treatment of SKF bearing steel in Jiangsu h***e little effect on the elastic modulus of the shaft. If the alloy steel or heat treatment is used to increase the stiffness of the shaft, it will fail. In addition, the alloy steel is more sensitive to stress concentration, and the stress concentration and surface roughness should be reduced from the structure.
自二十世纪以来，8。自一千九百八十世纪起，江苏SKF轴承球墨铸铁得到了迅速发展。例如，球墨铸铁复合曲轴的优点是成本低，耐磨性好，对应力集中的敏***低，但缺点是冲击韧度低，质量不易被C控制。
Since twentieth Century, 8. Since 1980th Century, Jiangsu SKF bearing nodular cast iron has been developing rapidly. For example, the advantages of the nodular cast iron composite crankshaft are low cost, good wear resistance and low sensitivity to force concentration, but the disadvantage is that the impact toughness is low and the quality is not easily controlled by C.
