江苏SKF轴承角接触球轴承的安装比深沟球轴承复杂得多。它们大部分是成对安装的。良好的安装可大大提高主机的工作精度和轴承寿命。否则,精度将不能满足要求,生命将受到影响。
The installation of SKF bearing angular contact ball bearings in Jiangsu is much more complicated than deep groove ball bearings. Most of them are installed in pairs. Good installation can greatly improve the working accuracy and bearing life of the main engine. Otherwise, accuracy will not meet the requirements, and life will be affected.
安装SKF角接触球轴承有三种方法:背对背、面对面和串联连接。当背靠背(两轴承的宽端)安装时,江苏SKF轴承轴承的接触角线沿旋转轴线传播,这可以增加径向轴承和轴向轴承的角刚度和抗变形能力。
There are three ways to install SKF angular contact ball bearings: back to back, face to face and series connection. When the back to back (the wide end of the two bearing) is installed, the contact angle line of the bearing of the Jiangsu SKF bearing is propagated along the axis of rotation, which can increase the angular stiffness and the maximum anti deformability of the radial and axial bearings.
当安装表面(两个轴承为窄端)时,江苏SKF轴承的接触角收敛到旋转轴。角刚度小。当轴承内圈从外圈伸出时,当两个轴承的外圈被压在一起时,消除了外圈的原始间隙,从而增加了轴承的预载荷。
When the installation surface (two bearings are narrow ends), the contact angle of Jiangsu SKF bearing converges to the rotation axis. The angular stiffness is small. When the inner ring of the bearing extends out of the outer ring, when the outer ring of the two bearings is pressed together, the original clearance of the outer ring is eliminated, thereby increasing the preload of the bearing.
当串联布置(两个轴承在一个方向的宽端)时,江苏SKF轴承的接触角线平行且平行,使得两个轴承在同一方向上分担工作负载。然而,为了***安装的轴向稳定性,必须在轴的相对端安装两对轴承。
When the series arrangement (two bearings are in the wide end of one direction), the contact angle lines of the Jiangsu SKF bearing are parallel and parallel, making the two bearings share the working load in the same direction. However, in order to ensure the axial stability of the installation, two pairs of bearings must be installed at the opposite end of the shaft.
江苏SKF轴承预压可以通过磨削轴承环的内圈或两个不同的厚度环来完成。预紧轴承与球之间的紧密接触使球与滚道紧密接触。
The SKF bearing preloading in Jiangsu can be accomplished by grinding the inner ring of the bearing ring or two different thickness rings. The tight contact between the preloaded bearing and the ball causes the ball to be in close contact with the raceway.
预压载荷对江苏SKF轴承的寿命有很大的影响。根据相关数据,当轴承组件具有0.012mm干扰时,当0.016mm受到干扰时,使用寿命减少38%,使用寿命减少50%。
The preloading load has great influence on the life of SKF bearing in Jiangsu. According to the relevant data, when the bearing assembly has 0.012mm interference, when the 0.016mm is disturbed, the service life is reduced by 38% and the service life is reduced by 50%.
当江苏SKF轴承总成间隙为0.4 4mm时,使用寿命缩短,间隙为0.8~8mm时,使用寿命在使用寿命之内。下降70%。
When the gap of Jiangsu SKF bearing assembly is 0.4 4mm, the service life is shortened, and the gap is between 0.8 and 8mm, and the service life is within service life. Down 70%.
因此,合理选择预压的大小是非常重要的。一般来说,应该选择小的预载来选择高速和低负荷。同时,预载荷应略大于或等于轴向工作载荷。
Therefore, it is very important to choose the size of preloading reasonably. Generally speaking, small preloads should be chosen to select high speed and low load. At the same time, the preload should be slightly larger than or equal to the axial working load.
