Attention to the installation and use of spherical roller bearings

 
The pre-tightening force of the aligning roller bearing is carried out at room temperature, but it is in working state. The pre-tightening force of the bearing will change when the driving shaft is generated by the rise of the micro-stretching temperature of the system. Therefore, you should take this factor into account when setting the pre-tightening force.
 
It requires the ability of the size, speed, and other conditioning Settings of the proper use of the aligning roller bearings to preload to ensure transmission life. If the pre - tightening force is too large, power consumption, even lead to overheating. If the pretension force is too small, the body load, the shaft rolling, the gap between the outer ring under the action of the pulsation, run, transmission accuracy, to reduce the noise increase, the impact of gear meshing, serious damage to the teeth and bearings.
 
According to different aligning roller bearing assembly, such as: directly from the axial compression of the internal bearing inner ring of the bearing prenut rotation, inner and outer rings to eliminate the gap, to achieve the purpose of bearing preload. Achieve common use: far more than the preloaded bearing, nut at the end, and then back 1/4 turn. Assembly method, the advantages of this method is less investment, simple, practical, consistent under the premise of good quality tapered roller bearings, it can be used.
