Heavy-duty lathe spindle static pressure During the trial operation and use, sometimes the tile accident occurs due to oil film damage. Whether it is dynamic pressure, static pressure or dynamic and static pressure bearing, its oil film thickness and its change are important basis for judging whether the main shaft is unstable or wattage. The system includes two parts: a high stability, high sensitivity eddy current sensor and a monitor. It can monitor the thickness of the oil film online. When the set value is exceeded, it can alarm and the operator can handle it according to the situation to avoid accidents. In order to obtain a monitoring system with high precision and stability, three key problems need to be solved; that is, the influence of the surface material of the bearing on the measurement accuracy of the eddy current sensor; the stability and accuracy of the eddy current sensor are improved: an intelligent monitoring instrument is developed.
