Impact FAG bearings life may be many factors and internal factors may cause sound has been further clarification, use. Used to adjust the main factor is to install, use and maintain, repair and maintenance, according to technical requirements. According to the bearings installation, use, maintenance, maintenance of the technical requirements for the operation of FAG bearings-contact load, speeds, lubrication State monitoring and inspection, found that the direct cause of the exception to adjust back to normal.
1, choose the right viscosity and good viscosity-temperature
Machine tools for machine tool spindle temperature is not too high heat variant, affecting the accuracy or poor lubrication of the bearings should be according to the spindle bearings structure, speed and bearings clearances, the right temperature of the lubricating oil and its viscosity-temperature characteristic of good, prevent spindle operating temperature and the ambient temperature changes is large, the viscosity change is too large and the impact of its lubricating properties.
2, choose good lubricity
For spindle and FAG bearings maintains uniform oil film between contact surfaces, and starts or stops the movement of spindle oil-film will not have an impact load damage, maintain good lubricating properties of reducing friction and friction heat, lower spindle Machining accuracy of temperature rise, ensuring role requires good lubricity.
3, good antioxidant
Spindle lubrication method, request spindle bearings oil long-term use without deterioration so requires a good antioxidant.
4, good corrosion resistance
Due to oil in spindle lubricating system of process inevitably mixed with air or condensed water in machine tool coolant, therefore called for oil has good rust inhibiting properties.
5, machine tool bearings are main components of precision machine tools and similar, which guarantees precision machine tool working accuracy and performance is critical.
Installation conditions, for bearings one of the factors is often caused by incorrect installation status changes of the gravity between the components of the package, FAG bearings temperature abnormal state of the primary factor, vibration, noise, progressive, and improve the quality of the original material. Raw material quality in the failure analysis of bearings the proportion has declined significantly, but it still is one of the main factors bearings failure.
Select still must take into account the appropriateness of bearings failure analysis. FAG bearings manufactured by forging, heat treatment, machining, lubrication conditions, to monitor and examine the exception found directly causes, adjusted back to normal. Installation conditions bearings one of the factors that is used is often caused by incorrect installation packages between different parts of gravity changes the State of the primary factor, without the normal operating state, and early termination of the inner life of the main factors, refers to a structural design, high quality manufacturing processes and materials, there are three factors that determine the quality of bearings.
