How to use spindle bearings to prolong their life and bring us greater benefits? Follow XEZ to find out!
- Installation of spindle bearings
Whether the installation of spindle bearing is correct affects the accuracy, life and performance. Therefore, the design and assembly department for the installation of spindle bearings is to be fully studied. It is expected to be installed according to operating standards. The standard items are usually as follows:
(1) Cleaning bearings and bearing associated parts
(2) Check the size and finishing of the associated parts
(3) Installation
(4) Check after installing bearings
(5) Supply lubricant
- Basic condition monitoring of spindle bearings
During use, the basic external conditions for the operation of spindle bearings should be monitored frequently, such as temperature, vibration and noise measurement, and so on. These regular inspections will identify potential problems early and will prevent unexpected machine stoppages, allowing production plans to be achieved and increasing plant productivity and efficiency.
- Re-lubrication of spindle bearings
In the process of operation, the bearing requires correct re-lubrication to perfect its performance. The method of bearing lubrication is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose the lubrication method suitable for the use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication prevails. But grease lubrication has the advantage of simplifying the structure around bearings.
- Unloading of spindle bearing
The spindle bearing should be replaced when it reaches its final life.
Although the spindle bearing can no longer be used, the original bearing is properly removed and the new bearing is replaced in time, which can play a good role in promoting the extension of the service life of the new bearing.
In many cases, the actual load of machine tool bearings increases significantly due to the influence of vibration. When the actual installation of machine tool bearings has a large coaxiality error (misalignment), the actual load of machine tool bearings will also increase, so it is necessary to correct the numerical value of the calculated load.
In some cases, it is also necessary to consider the axial force and radial force generated by the equipment itself, the weight of gears and other parts and even the weight of the shaft, the stress of the relevant parts, and they are all calculated in the bearing, load, and these are often easy to be ignored and missed.
