The method of fixing the inner and outer rings of the bearing depends on the specific bearing type and installation environment. Here are some common fixing methods:
1. Press-in method: Press the inner ring and outer ring of the bearing into the corresponding shaft and bearing seat respectively. This method is suitable for situations where the bearing size is small and the shaft and bearing seat have sufficient strength and stiffness.
2. Heating method: Heat the bearing to a certain temperature to expand it, and then press it into the shaft and bearing seat. This method is suitable for larger bearing sizes and softer shafts and bearing seats.
3. Cold mounting method: cold mount the inner ring and outer ring of the bearing into the corresponding shaft and bearing seat respectively. This method is suitable for situations where the bearing size is small and the shaft and bearing seat are soft.
4. Hot loading method: heat the bearing to a certain temperature to expand it, and then install it into the corresponding shaft and bearing seat. This method is suitable for situations where the bearing size is larger and the shaft and bearing seat are harder.
It should be noted that no matter which method is used, the installation accuracy of the inner and outer rings of the bearing must be ensured to ensure the normal operation and service life of the bearing.
