江苏INA轴承精度状态下的拆卸 来源:御狮轴承   点击:次   日期:2018-06-19 12:59

为了保证江苏INA轴承在安装后不会引起过度变形,必须做到:

In order to ensure that the INA bearing of Jiangsu will not cause excessive deformation after installation, it must be done:

1)肩轴和挡块孔的圆度和垂直度的精度应与轴承一致。

(1) the accuracy of roundness and perpendicularity of shoulder shafts and block holes should be consistent with bearings.

2)有必要精确地计算江苏INA轴承过盈配合的旋转环,并准确地计算合适的数量和固定环。

(2) it is necessary to accurately calculate the rotation ring of interference fit of Jiangsu INA bearing, and accurately calculate the appropriate number and fixed ring.

在江苏INA轴承小旋转环的范围内可以发现干扰量。只要离心力对工作温度下的热膨胀和最大速度有影响,就不会与蠕变或滑动面密切相关。根据工作载荷和轴承尺寸,固定环的最小间隙或过盈配合不利于原来的精确形状。

The amount of interference can be found in the range of INA bearing small rotating ring in Jiangsu. As long as centrifugal force affects the thermal expansion and maximum velocity at work temperature, it will not be closely related to creep or sliding surface. According to the working load and bearing size, the minimum clearance or interference fit of the fixed ring is not conducive to the original precise shape.

3)如果江苏INA轴承的工作温度在高速条件下较高,则应特别注意旋转环的配合,防止偏心环与固定环之间的匹配,并防止环变形和激振。在负载下。

(3) if the working temperature of the INA bearing in Jiangsu is higher in high speed conditions, special attention should be paid to the matching of the rotating ring to prevent the matching between the eccentric ring and the fixed ring, and prevent the ring deformation and excitation. Under the load.

固定环的干涉配合小,精度高,两侧粗糙度低。否则,很难去除和去除。此外,江苏INA轴承主轴的伸长的影响是必要的。

The fixed ring has small interference fit, high precision and low roughness on both sides. Otherwise, it is difficult to remove and remove. In addition, the effect of elongation of INA bearing spindle in Jiangsu is necessary.

5)使用一对双角接触球轴承主轴,超过一半的负载轻,大的干涉等,内部轴向预紧力将明显较大,造成不利影响。双列圆柱滚子轴承和圆锥滚子轴承具有较大的载荷和较大的过盈配合。

(5) the use of a pair of double angle contact ball bearing spindle, more than half of the load light, large interference and so on, the internal axial pretightening force will be significantly larger, causing adverse effects. Double row cylindrical roller bearings and tapered roller bearings have larger loads and larger interference fit.

为了提高江苏INA轴承安装的匹配精度,必须采用生产方法和工具来测量轴承的变形。它能准确测量轴承孔和外圈的尺寸,并能测量内径和外径的所有测量项目,并对测量数据进行综合分析。因此,轴承轴和缸体孔尺寸被精确测量。当测量轴和孔的尺寸和形状时,它们应在相同的温度和轴承上。

In order to improve the matching accuracy of INA bearing installation in Jiangsu, production methods and tools must be used to measure the deformation of bearings. It can accurately measure the size of bearing bore and outer ring, and can measure all measuring items of inner diameter and outer diameter, and make comprehensive analysis of the measured data. Therefore, the dimensions of bearing shaft and cylinder bore are accurately measured. When measuring the size and shape of the shaft and hole, they should be on the same temperature and bearing.
