在安装和拆卸轴承时，如何掌握施加力的大小？
When installing and disassembling bearings, how to grasp the magnitude of the applied force?
（1）力应稳定、均匀，不得冲击，要求使用能施加稳定张力或压力的油压或工具。事实上，bi须使用锤击时，也应使用软金属和无屑金属（如铜套）进行缓冲，冲击力应尽可能小。***好用铜棒或锤子。
(1) The force shall be stable and uniform, and shall not be impacted, requiring the use of oil pressure or tools capable of exerting stable tension or pressure. In fact, when Bi needs to be hammered, soft metal and scrapless metal (such as copper sleeve) should also be used to buffer, and the impact force should be as ***all as possible. *** is good at using copper rods or hammers.
（2）保持适当的牵引力。例如，当淮安NSK轴承安装在正确的位置时，应停止牵引，以确保环（垫圈）的端面与座孔或轴的肩面之间没有过度紧密或不足。
(2) Maintain proper traction. For example, when Huaian NSK bearings are installed in the correct position, traction should be stopped to ensure that there is no excessive tightness or insufficiency between the end face of the ring (washer) and the shoulder face of the seat hole or shaft.
（3）施加的合力应尽可能通过支座轴线，要求作用点均匀、对称、稳定，并通过球体或平行于轴线施加力。
(3) The resultant force applied should pass through the axis of the support as far as possible, requiring the action point to be uniform, symmetrical and stable, and exerting force through the sphere or parallel to the axis.
（4）为了避免淮安NSK轴承通过滚动元件施加力，滚动元件要求内环（轴环）通过内环加载，外环通过外环加载。
(4) In order to ***oid Huaian NSK bearing exerting force through rolling element, rolling element requires inner ring (axle ring) to be loaded through inner ring and outer ring to be loaded through outer ring.
轴承的精度、寿命和性能受安装的影响。如果您希望轴承性能良好，应在每个安装步骤中做好工作，以确保安装不会影响轴承的精度、寿命和性能。以下安装方法不影响轴承的精度、寿命和性能。
The accuracy, life and performance of bearings are affected by installation. If you want the bearing to perform well, you should do a good job in each installation step to ensure that the installation will not affect the accuracy, life and performance of the bearing. The following installation methods do not affect the accuracy, life and performance of bearings.
当轴承内圈与轴紧密配合，外圈与淮安NSK轴承座孔松配合时，可先用压具将轴承压在轴上，再将轴与轴承一起装入轴承座孔。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。装配套筒的内径应略大于轴颈和轴承内圈的内径。边缘稍微小一些，以免压到保持架上。当轴承外圈与轴承座孔配合紧密，内圈与轴配合松时，可先将轴承压入轴承座孔内，配合管的外径应略小于轴承座孔的直径。如果淮安NSK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 bearing is closely matched with the shaft and the outer ring is loosely matched with the seat hole of Huaian NSK bearing, the bearing can be first pressed on the shaft by a press, and then the shaft and the 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 assembly sleeve should be slightly larger than that of journal and bearing inner ring. The edge is slightly ***aller so as not to press 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 ***aller than the diameter of the bearing seat hole. If Huaian NSK bearing rings are closely matched with the shaft and seat holes, the inner and outer rings shall be pressed into the shaft and seat holes 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.
轴承与轴的整体配合一般为过渡配合，座圈与轴承座孔的配合一般为间隙配合。因此，轴承易于安装。双向推力轴承的中轴弹簧应固定在轴上，以防止相对于轴转动。轴承安装一般以轴的转动为基础，因此内环与轴是双赢的，外圈与轴承室是间隙配合。
The overall fit of bearing and shaft is generally transitional fit, and the fit of seat ring and bearing seat hole is generally clearance fit. Therefore, bearings are easy to install. The mid-axle spring of bi-directional thrust bearing should be fixed on the axle to prevent rotation relative to the axle. Bearing installation is generally based on the rotation of the shaft, so the inner ring and the shaft are win-win, and the outer ring and the bearing chamber are clearance fit.
