Abstract | PURPOSE: A high-speed spindle device equipped with a piezoelectric load sensor is provided to prevent an overload applied to a spindle and a bearing by controlling an axial load applied to the spindle. CONSTITUTION: A high-speed spindle device equipped with a piezoelectric load sensor comprises a spindle(100), a bearing(200), a bearing housing(300), a spindle housing(700), a sensor ring(500), and a piezoelectric load sensor. The inner ring(210) of the bearing is coupled to the outer surface of the spindle to rotate the spindle. The outer ring(220) of the bearing is fixed to the bearing housing. The bearing housing is inserted into the spindle housing. The sensor ring is installed between a bearing housing flange(310) of the bearing housing and the spindle housing and supports an axial load. The piezoelectric load sensor is installed inside the sensor ring and senses the axial load applied to the spindle. |
