What is the assembly method of thrust angular contact ball bearings?

1.jpg

The bearing precision of thrust angular contact ball bearings is much higher than that of thrust ball bearings, and the speed it can withstand is also much higher, so it can be used as a spindle bearing. However, improper bearing installation will fail to achieve such an effect. So, which assembly method can be used to achieve twice the result with half the effort?

According to reports, thrust angular contact ball bearings are generally back-to-back, because back-to-back can withstand axial forces in two directions.

The load lines of bearings paired back-to-back are separated toward the bearing axis. It can withstand axial loads acting in two directions, but the load in each direction can only be borne by one bearing. Bearings mounted back to back provide a relatively rigid bearing arrangement and can withstand overturning moments. When using this assembly method, please pay attention to:

1.The verticality of the shaft ring and the shaft centerline should be checked. The method is to fix the dial indicator on the end face of the box shell, so that the contact head of the dial is on the raceway of the bearing shaft ring and rotate the bearing while observing the dial indicator pointer. If the pointer is deflected, it means that the shaft ring and the center line of the shaft are not perpendicular. When the box shell hole is deep, an extended dial indicator can also be used for inspection.

2.When installed correctly, its seat ring can automatically adapt to the rolling of the rolling elements, ensuring that the rolling elements are located on the upper and lower raceways. If installed upside down, not only will the bearing not work properly, but also the mating surfaces will be severely worn. Since the difference between the shaft ring and the seat ring is not very obvious, extra care should be taken during assembly to avoid making mistakes.

3.In addition, a gap of 0.2-0.5mm should be left between the bearing seat ring and the bearing seat hole to compensate for errors caused by inaccurate parts processing and installation. When the center of the bearing ring deviates during operation, this gap can be Make sure it adjusts automatically and avoids contact and friction to keep it functioning properly. Otherwise, severe damage to the bearing will occur.

4.Before installation, please check whether the bearing box is clean and worn, etc. Also remember to install the bearing, press the end cover, check the flexibility of the rotor, and then install the entire part on the screw rod. If you install the screw rod first and then press the end cap, it may cause the bearing to be unable to be aligned, stuck, and prone to heat, etc.!

5.Another point is that there are V and 0 marks on the bearing. This is the place where the bearing accuracy is high. It should be installed in the place where the bearing box marking jumps the most. This combination can compensate for the error of the workpiece and make the rotation accuracy achieve dynamic balance!
