产品详细说明
 提高江苏SKF轴承主轴的速度是实现高速、实用主轴的关键。随着高速的发展,高效的机床正在研制中。轧制材料由陶瓷材料制成。DMN值约为20×104。数控加工中心的DMN值在润滑脂下为100×104,数控加工中心不断增加。它已成为一种发展趋势。油气润滑和油雾润滑也将成为未来高速机床主轴江苏SKF轴承润滑的发展方向。

Improving the speed of SKF bearing spindle in Jiangsu is the key to achieve high speed and practical spindle. With the development of high speed, efficient machine tools are being developed. The rolling material is made of ceramic material. The DMN value is about 20 * 104. The DMN value of CNC machining center is 100 x 104 under grease, and CNC machining center is increasing. It has become a trend of development. Oil and gas lubrication and oil mist lubrication will also become the future development direction of Jiangsu SKF bearing lubrication for high speed machine tool spindle.

1,高速主轴轴承的研制

1, development of high speed spindle bearing

一般来说,高刚性和高速性能的角接触球江苏SKF轴承通常用于满足机床主轴的高速要求。第二,使用圆柱滚子轴承。

Generally speaking, high rigidity and high-speed performance of angular contact ball Jiangsu SKF bearings are usually used to meet the high-speed requirements of machine tool spindle. Second, cylindrical roller bearings are used.

在润滑脂条件下,DMN值小于50×104。随着油气润滑的发展,相应的润滑系统也逐渐发展起来。主轴江苏SKF轴承DMM的高速性能(DM为轴承圆直径mm×n为速度r/min),DMN值达到100×104。

Under the condition of grease, the DMN value is less than 50 * 104. With the development of oil and gas lubrication, the corresponding lubrication system has gradually developed. High speed performance of spindle Jiangsu SKF bearing DMM (DM is mm diameter n diameter of bearing circle diameter is r/min), DMN value reaches 100 * 104.

滚动江苏SKF轴承的角接触球轴承也是在轴承中发展起来的。DMN值为200×104×104×90s,射流润滑的DMN值可达到300×104。

The angular contact ball bearings for rolling Jiangsu SKF bearings are also developed in bearings. The DMN value is 200 x 104 x 104 x 90s, and the DMN value of jet lubrication can reach 300 * 104.

高速角接触球江苏SKF轴承可以看出圆锥滚子轴承、单列和双列圆柱滚子轴承在高速性能方面不如角接触球轴承。角接触轴承是一种具有接触角的轴承。

High speed angular contact ball bearings of Jiangsu SKF can be seen that tapered roller bearings, single row and double row cylindrical roller bearings are not as good as angular contact ball bearings in terms of high speed performance. Angular contact bearing is a kind of bearing with contact angle.

接触角越大,江苏SKF轴承轴向刚度越好,但陀螺仪和滚道之间的旋转滑移越大,热量越大。为了提高速度性能,该方法是减小球的尺寸(或质量),改变通道的曲率系数,以减小球的离心力,以减少高速产生的内部载荷,并增加球的数量来改善球。他很固执。

The greater the contact angle, the better axial stiffness of SKF bearing in Jiangsu, but the greater the rotation slip between gyroscope and raceway, the greater the heat. In order to improve the speed performance, the method is to reduce the size (or mass) of the ball, to change the curvature coefficient of the channel, to reduce the centrifugal force of the ball, to reduce the internal load produced at high speed, and to increase the number of balls to improve the ball. He is very stubborn.

3,高速主轴轴承润滑

高速主轴江苏SKF轴承的发展趋势对润滑提出了更高的要求。传统的润滑脂在50×104以下的DMN值因其简单、经济的用途而被广泛应用。无需特殊维护,无需随访。它们大多是终身润滑。

The development trend of high speed spindle SKF bearings in Jiangsu has put forward higher requirements for lubrication. The traditional DMN value of grease under 50 * 104 is widely used for its simple and economical uses. There is no need for special maintenance and no need for follow-up. Most of them are life-long lubrication.

随着江苏SKF轴承转速的增加,当DMN值超过100×104时,采用油气润滑和油雾润滑。与润滑脂相比,温度升高不大,且能高速旋转,成为主要润滑模式。虽然喷射润滑的DMN值可以达到250×104,但需要大量的润滑油。由于搅拌阻力大,功率损失大,需要复杂的辅助设备,价格昂贵,一般不使用。

With the increase of rotational speed of SKF bearing in Jiangsu, when DMN value exceeds 100 * 104, oil air lubrication and oil mist lubrication are adopted. Compared with grease, the temperature increases little, and it can rotate at high speed, becoming the main lubrication mode. Although the DMN value of jet lubrication can reach 250 x 104, a large amount of lubricating oil is needed. Because of the large stirring resistance and high power loss, complex auxiliary equipment is needed, which is expensive and generally not used.
