江苏INA轴承未来发展方向专用要求 来源:御狮轴承   点击:次   日期:2018-07-04 10:01

进口轴承的接触疲劳寿命对钢结构的均匀性非常敏感。逐步清洗(减少钢中杂质和夹杂物的含量)使江苏INA轴承非金属夹杂物和碳化物均匀分布在钢中,提高了轴承钢的接触疲劳寿命。

The contact fatigue life of imported bearings is very sensitive to the uniformity of steel structure. The gradual cleaning (reducing the content of impurities and inclusions in steel) makes the non-metallic inclusions and carbides evenly distributed in the steel of the Jiangsu INA bearing and improves the contact fatigue life of the bearing steel.

江苏INA轴承钢的显微组织应均匀分布在均匀碳化物颗粒的回火马氏体基体上,使轴承钢具有所需的性能。高碳轴承钢中的主要合金元素是碳、铬、硅、锰和钒。

The microstructure of INA bearing steel in Jiangsu should be evenly distributed on tempered martensite matrix of homogeneous carbide particles, so that bearing steel has the required properties. The main alloying elements in high carbon bearing steel are carbon, chromium, silicon, manganese and vanadium.

20世纪70年代以来,随着经济的发展和工业技术的进步,江苏INA轴承的应用范围不断扩大。国际贸易的发展促进了轴承钢国际化和新技术、新技术标准的发展和应用。

Since 1970s, with the development of economy and the progress of industrial technology, the application scope of INA bearings in Jiangsu has been expanding. The development of international trade has promoted the development and application of bearing steel internationalization and new technology and new technology standards.

技术和新设备,以及高效率、高质量、低成本的支撑技术和装备应运而生。Gao Jie网和优质轴承钢生产线分别建在日本和德国。钢产量迅速增加,钢的质量和疲劳寿命大大提高。

Technology and new equipment, as well as efficient, high-quality, low-cost support technology and equipment emerge as the times require. Gao Jie network and high quality bearing steel production line are built in Japan and Germany respectively. The output of steel has increased rapidly, and the quality and fatigue life of steel have been greatly improved.

在日本和瑞典生产的江苏INA轴承钢的氧含量小于10ppm80年代后期,日本山阳特钢公司的先进水平达到5.4ppm,达到了真空重熔轴承钢的水平。

The oxygen content of Jiangsu INA bearing steel manufactured in Japan and Sweden is less than 10ppm。 In the late 80s, the advanced level of Shanyang special steel company of Japan reached 5。4ppm and reached the level of vacuum remelting bearing steel。

1,抗振刚度

1, anti vibration stiffness

为了保证机床的加工质量,主轴系统必须具有足够的刚度,否则会产生较大的回波误差甚至颤振。江苏INA轴承抗振性是指抵抗强迫振动和自激振动的能力。主轴组件的抗振性取决于主轴和轴承的刚度和阻尼。采用预紧滚动轴承,可有效提高主轴系统的刚度。

In order to ensure the machining quality of the machine tool, the spindle system must have enough stiffness, otherwise it will produce larger echo error or even chatter。 The vibration resistance of INA bearings in Jiangsu is the ability to resist forced vibration and self excited vibration。 The vibration resistance of the spindle assembly depends on the stiffness and damping of the spindle and bearing。 The rigidity of the spindle system can be effectively improved by using pre tightening rolling bearings。

2,噪音

2, noise

在高速磨床中,磨头轴承的噪声是整机噪声的主要组成部分。应选用低噪声滚动轴承。

In high speed grinder, the noise of grinding head bearing is the main component of the whole machine noise。 Low noise rolling bearings should be selected。

3,寿命与承载力

3, life and bearing capacity

对于普通机床来说,江苏INA轴承主轴组件的寿命主要是指保持主轴精度的时限。因此,轴承的精度要求满足主轴装配寿命的要求。对于重型机床或重型切削机床,首先应考虑轴承的承载能力。

For ordinary machine tools, the life of Jiangsu INA bearing spindle assembly mainly refers to the time limit for maintaining spindle accuracy。 Therefore, the accuracy requirements of bearings meet the requirements of spindle assembly life。 For heavy-duty machine tools or heavy duty cutting machines, bearing capacity of bearing should first be considered。

4,速度与成功

4, speed and success

随着科学技术的发展,机床主轴转速越来越高,速度范围越来越大。因此,高速轴承的稳定性要求越来越高。江苏INA轴承主轴轴承温升是影响轴承转速的重要因素。一般而言,轴承类型、公差等级、配置方式、间隙(预载荷)尺寸、润滑剂和润滑方法可以在一定程度上提高滚动轴承的高速性能。

With the development of science and technology, the spindle speed of machine tool is higher and higher, and the speed range is bigger and bigger。 Therefore, the stability requirements of high speed bearings are getting higher and higher。 The temperature rise of INA bearing spindle bearing in Jiangsu is an important factor affecting bearing speed。 Generally speaking, bearing type, tolerance grade, configuration mode, clearance (pre load) size, lubricant and lubrication method can improve the high speed performance of rolling bearing to a certain extent。
