Lubrication system for machine tool or the like.

摘要

A lubricating system for a machine tool or the like includes a temperature sensor for measuring spindle bearing temperature and two pairs of thrust sensors for measuring radial and axial spindle deflection. Data processing apparatus, typically comprised of a microcomputer, is coupled to the temperature and thrust sensors and regulates the percentage of oil in the oil-air mixture lubrication mist sprayed on bearing contact surfaces in accordance with bearing temperature.
