进口轴承安装相关事项及安装方法？
imported bearing installation related matters and installation methods?
进口轴承的安装与其自身的重要性能有关。进口轴承越重要，就越需要注意。安装问题越清楚，进口轴承的安装方法就越重要。进口轴承的安装注意事项和方法如下。
The installation of imported bearing is related to its own important performance. The more important imported bearings are, the more attention they need. The clearer the installation problem is, the more important the installation method of imported bearing is. The installation precautions and methods of imported bearings are as follows.
一、淮安INA轴承及相关部件的清洁
I. Cleaning of Huaian INA Bearings and Related Components
对于润滑脂润滑的进口轴承和带油封或防尘罩的双面轴承，安装前无需清洗密封圈轴承。
For imported bearings lubricated with grease and double-sided bearings with oil seal or dust cover, there is no need to clean the sealing ring bearings before installation.
二。检查相关零件的尺寸和表面处理
Two. Check the dimensions and surface treatment of related parts
三、安装方法
III. Installation Method
进口轴承的安装应根据轴承结构、尺寸和轴承部件的匹配性质而定。压力应直接施加在配合环的端面上，压力不应通过滚动件传递。
Installation of imported bearings should be based on bearing structure, size and matching nature of bearing components. The pressure should be applied directly on the end face of the mating ring, and the pressure should not be transferred through the rolling parts.
1。压力配合
1. Pressure fit
当进口轴承的内环与轴紧密配合，外环与轴承座孔松配合时，可先用压具将轴承压在轴上，再将轴与淮安INA轴承一起装入轴承座孔中。压装时，将软金属材料制成的装配套（铜或软钢）垫在轴承内环的端面上。装配套管的内径应略大于轴颈的内径，装配套管的外径应大于轴承的外径。内环边缘稍微小一些，以避免对保持架产生压力。当轴承外圈与轴承座孔紧密配合，内圈与轴松配合时，可先将轴承压入轴承座孔，配合管的外径应略小于轴承座孔的直径。如果轴承环与轴和座孔紧密配合，内外环应同时压入轴和座孔中。装配套的结构应同时拧紧轴承内外环的端面。
When the inner ring of the imported bearing is closely matched with the shaft and the outer ring is loosely matched with the bearing seat hole, the bearing can be first pressed on the shaft with a press, and then the shaft and Huaian INA bearing are loaded into the bearing seat hole together. When pressing, the assembly sleeve (copper or mild steel) made of soft metal material is padded on the end face of the inner ring of the bearing. The inner diameter of the assembled casing should be slightly larger than that of the journal, and the outer diameter of the assembled casing should be larger than that of the bearing. The inner ring edge is slightly smaller to avoid pressure on the cage. When the outer ring of the bearing is closely matched with the bearing seat hole and the inner ring is loosely matched with the shaft, the bearing can be pressed into the bearing seat hole first, and the outer diameter of the matching pipe should be slightly smaller than the diameter of the bearing seat hole. If the bearing ring is closely matched with the shaft and the seat hole, the inner and outer rings shall be pressed into the shaft and the seat hole at the same time. The structure of the assembly sleeve should tighten the end face of the inner and outer rings of the bearing at the same time.
2。加热协调
2. Heating coordination
通过加热进口轴承或淮安INA轴承座，通过热膨胀将紧配合转变为松配合。这是一种常见且省力的安装方法。该方法适用于大扰动轴承的安装。热负荷前，将轴承或可分离轴承的套圈放入油箱，在80-100℃下均匀加热，然后将套圈从油中取出，并尽快装到轴上。为了防止冷凝后内环端面与轴肩不紧密配合，冷凝后可轴向拧紧轴承。当轴承外圈与轻金属轴承座紧密配合时，可采用加热轴承座的热装方法，避免接触面划伤。用油罐加热淮安INA轴承时，应在距油罐底部一定距离处设置网孔，或用钩子挂上轴承。轴承不应放置在油箱底部，以防止凹陷的杂质进入轴承或加热不均匀。油箱内bi须安装温度计，严格控制油温不超过100摄氏度，防止回火，降低壳体硬度。
By heating the imported bearing or Huaian INA bearing seat, the tight fit is transformed into loose fit by thermal expansion. This is a common and labor-saving installation method. This method is suitable for installation of large disturbance bearing. Before the heat load, the rings of bearings or separable bearings are put into the oil tank and heated uniformly at 80-100 C. Then the rings are removed from the oil and loaded onto the shaft as soon as possible. In order to prevent the end face of the inner ring from not tightly matching with the shoulder after condensation, the bearing can be tightened axially after condensation. When the outer ring of the bearing is closely matched with the light metal bearing seat, the hot charging method of heating the bearing seat can be adopted to avoid scratches on the contact surface. When heating Huaian INA bearing with oil tank, mesh holes should be set at a certain distance from the bottom of the tank, or the bearing should be hooked. Bearings should not be placed at the bottom of the tank to prevent sunken impurities from entering the bearing or uneven heating. The Bi in the tank should be installed with thermometer, strictly control the oil temperature not to exceed 100 degrees Celsius, prevent tempering and reduce the hardness of the shell.
