The Inspection of Thrust Bearings after Installation
The thrust bearing is a bearing that is specially designed to support thrust (axial) loads. It can also provide moderate radial guidance, and seeks to minimize frictional resistance while relieving thrust loads distributes them to the places where they can be most effectively transmitted. Therefore, it is necessary to carry out inspection after the installation of thrust bearings to make sure the quality of bearings, and to ensure the normal operation of the machine.
First, there should be an inspection on the installation quality and the correct axial position. According to the requirements of the installation direction, the lubrication and the preload, the installation quality of the thrust bearing should be checked. The preload and the gap of thrust bearings should be adjusted in accordance with technical requirements, and the axial position should be accurate within tolerance range.
Second, for the installation of inner and outer rings, attention must be paid to the same position of the inner and outer rings. If the same position of the inner and outer rings is not the same, the inner and outer rings will generate the axial clearance, which will affect the transmission performance of the bearing and lead to bearing failure.
Third, it is necessary to inspect the shape, size and structure of the thrust bearing itself and handle any uncompliant product. Then it is necessary to check whether the thrust bearing can be loaded or not. It is necessary to check whether the load is normal and whether the set turning torque is blocked.
Finally, when the thrust bear is installed, an inspection should be carried out to ensure that the parts which are associated with the thrust bear including the seat and the shell are normal without any loose, looseness and damage. While ensuring the above conditions, attention should also be paid to whether the oil standard is correct and whether the lubrication is normal.
In conclusion, the inspection of thrust bearings after installation is quite important. In addition to checking whether it can load normally and pay attention to oil level and lubrication, it is also necessary to check the axial position and the axial clearance of the inner and outer rings, verify the installation quality, and take necessary measures for noncompliant products. Only in this way can we ensure the normal operation of the thrust bearings and the entire machine.
