Whole eccentric bearing service life may be many factors can cause internal friction factor and sound has been further instructions, use. Used to adjust the installation are the main factors, use and maintenance, repair and maintenance, according to technical requirements. Bearing installation, use, maintenance, maintenance of technical requirements for the operation of the bearing contact loads, speeds, lubrication State monitoring and inspection, found that the direct cause of the exception to adjust back to normal.
1, select the appropriate viscosity and good viscosity-temperature
For the spindle of the machine temperature is not too high thermal variant, affecting the accuracy or eccentric so that the overall poor lubrication of bearings, according to spindle bearing structure, speed and temperature of the bearing clearance right and call it good viscosity-temperature properties of lubricating oil to prevent the spindle when the working temperature and the ambient temperature varies, changes in viscosity is too large to affect its lubricating properties.
2, choose good lubricity
To make the spindle-bearing interface between a uniform oil film, and start or stop the movement of spindle oil film is not damaged when the shock loads, good lubrication reduces friction and frictional heat, lower the spindle temperature rise, ensuring accuracy, requires a good lubricating properties.
3, good oxidation resistance
Spindle lubrication method, require long-term use without deterioration of spindle bearing oil requires a good antioxidant.
4, good corrosion resistance
Because of oil in spindle lubrication system work inevitably mixed with air or condensed water in machine tool coolant, therefore requests that the oil has good rust inhibiting properties.
