江苏INA轴承滚珠转动动能的压力释放 来源:御狮轴承   点击:次   日期:2018-06-01 11:22

江苏INA轴承由于在螺杆轴和滚珠丝杠之间有一个INA进口轴承,所以许多球被旋转,因此它们失去了更高的活动顺应性。与以前的滑动螺杆副相比,驱动转矩小于1/3,也就是说,实现异常效果所需的功率是使用1/3的旋转螺杆对。这对节约用电很有帮助。

The Jiangsu INA bearing has a INA inlet bearing between the screw shaft and the ball screw, so many balls are rotated, so they lose higher activity compliance. Compared with the previous sliding screw pair, the driving torque is less than 1/3, that is to say, the power required to achieve the abnormal effect is the rotary screw pair using 1/3. This is very helpful for saving electricity.

江苏INA轴承滚珠丝杠副是由日本制造的最高水平的机器制造的。此外,在切割、装配和检查过程中,必须严格控制温度和湿度。由于全面质量管理体系,精密度得到了充分的保证。

Jiangsu INA bearing ball screw pair is made of the highest level machine manufactured in Japan. In addition, temperature and humidity must be strictly controlled in the process of cutting, assembling and checking. Due to the total quality management system, precision has been fully guaranteed.

由于江苏INA轴承压力可使轴向间隙为负值,因此可对滚珠丝杠副进行加压,从而失去较高的刚性。滚珠丝杠承受滚珠丝杠上的滚珠压力。在实际的机器安装中,由于球的斥力,可以加强金属丝的刚性。

Because the INA bearing pressure in Jiangsu can make the axial gap negative, the ball screw can be pressurized, thereby losing higher rigidity. Ball screws bear ball pressure on ball screws. In actual machine installation, because of the repulsive force of the ball, the rigidity of the wire can be strengthened.

基于喷丸强化的工件表面残余应力的原因是基于AbObID等人的概念。当江苏INA轴承高速钢球撞击试样表面时,冲击位置会产生塑性变形和残余压力坑,当越来越多的钢撞击时,冲击位置会产生塑性变形和残余压力坑。

The cause of residual stress on the workpiece surface based on shot peening is based on the concept of AbObID et al。 When the Jiangsu INA bearing high speed steel ball hits the surface of the specimen, the impact position will produce plastic deformation and residual pressure pit。 When more and more steel impact, the impact position will produce plastic deformation and residual pressure pit。

当球撞击试样表面时,INA轴承的均匀塑性层将出现在试样表面上。由于塑性变形层的体积收缩受到非塑性变形区的限制,整个塑性变形层受到压缩应力。

When the ball hits the surface of the specimen, the uniform plastic layer of the INA bearing will appear on the surface of the sample。 Because the volume shrinkage of the plastic deformation layer is restricted by the non plastic deformation zone, the whole plastic deformation layer is subjected to compressive stress。

残余应力及其分散性对齿轮的疲劳寿命有很大影响。喷丸工艺的质量将间接影响其残余应力和分散性。因此,准确测量喷丸表面残余应力是评价喷丸质量的一种有效方法。

The residual stress and its dispersion have great influence on the fatigue life of gears. The quality of shot peening process will indirectly affect its residual stress and dispersion. Therefore, accurate measurement of residual stress on shot peening is an effective method to evaluate shot peening quality.

江苏INA轴承喷丸可导致零件塑性变形,零件表面粗糙度会发生变化。表面粗糙度是一种微形态偏差,也称微弯曲。表面粗糙度与表面波和形状偏差相同,都属于零件的形状偏差。外表面粗糙度对刚性零件的性能有重要影响。

Jiangsu INA bearing shot peening can lead to plastic deformation of parts and surface roughness of parts will change. Surface roughness is a micromorphological deviation, also known as micro bending. The surface roughness is the same as the surface wave and shape deviation, all of which belong to the shape deviation of the parts. The roughness of external surface has important influence on the performance of rigid parts.

江苏INA轴承喷丸处理对表面粗糙度的影响通常在Ra0.620mm范围内。在不改变工艺参数的情况下,原料粗糙度越高,喷丸后的Ra值越大。生产理论证明,在一般条件下,喷丸表面粗糙度低于6.3mm,喷丸处理可以改善或保持原始表面粗糙度。

The impact of shot peening on the surface roughness of Jiangsu INA bearings is usually within the range of Ra0。6 to 20mm。 Without changing the process parameters, the higher the roughness of raw materials, the greater the Ra value after shot peening。 Production theory has proved that under general conditions, the surface roughness of shot peening is lower than 6。3mm, and shot peening can improve or maintain the original surface roughness。

假设江苏INA轴承原始表面粗糙度在6.3mm以上,喷丸表面粗糙度较低。在生产理论中,为了实现喷丸强化的更为雄心勃勃的外观,我们应从以下几个方面着手:一是提供更好的原始外观,RA值应低于6.3mmINA进给轴承的球直径和喷丸压力是SE。乐。大直径钢球喷丸处理后,球磨压力较小(不改变喷丸强度)。当覆盖一次值时,可获得良好的表面粗糙度。

Assuming that the original surface roughness of Jiangsu INA bearing is above 6.3mm, the surface roughness of shot peening is low. In production theory, in order to achieve a more ambitious appearance of shot peening, we should start from the following aspects: one is to provide a better original appearance, the RA value should be lower than 6.3mm; the ball diameter and shot peening pressure of the INA feed bearing are SE. HappyAfter large diameter shot peening, the ball milling pressure is small (no change in shot peening strength). When the primary value is covered, good surface roughness can be obtained.
