| Static Harbin Bearing to rotary accuracy, high rigidity, high bearing capacity, no wear, high durability and is widely used in M210, M131W, 2A710, FYT10 and 3160A grinding diamond boring head. With the development of NC technology, static Harbin Bearing is also widely used in machining centers, CNC machine tool spindle. Static Harbin Bearing how to maintain? The 1 orifice restrictor. (1) the inner throttle to external throttle, and to install pressure gauge real-time display of cavity pressure, can make the repair and maintenance convenience, especially can be easily cleaned regularly, this is an internal restrictor incomparable. (2) the ratio of throttle. Throttle ratio β theoretical value is 1.2 ~ 1.5, and according to the experience of 1.25 was better. In this repair, need, before and after the geometric accuracy of spindle bearing geometric accuracy, coaxial, roundness and taper of strict control, in order to ensure that the beta value. According to the bearing capacity of machine tool to determine e value (eccentricity of spindle and the bearing geometric center), the value of the best. (3) in the oil chamber is not arranged spindle, each column of oil oil port must be consistent (observation), if not, should adopt the method to change the throttle aperture, change its flow. The 4 chamber as an example, the general, left, right chamber of the oil column was between 20 ~ 25mm, hole diameter of 0.25 ~ 0.4mm 2 static pressure in the oil supply system of Harbin Bearing, in addition to coarse filter, fine filter, the rest of the element has a protective effect on the static pressure Harbin Bearing. In the original system based on the fuel supply system improvement. (1) the throttle plate after the oil outlet pressure relay and the pressure gauge (originally in front of the accumulator), this will enable the operator to see cavity pressure and inlet pressure. When the pressure is greater than a certain value, in order to immediately shut down, so as to avoid bearing locking. Such as: inlet pressure 2MPa, outlet pressure of 1.2 to 1.6MPa, less than 1.2MPa must stop. (2) increased 0.04 ~ 0.05mm gap between the spindle and the bearing pressure of Harbin Bearing digital detection device, during which the oil has a certain degree of resistance, detect the changes in this resistance, we can know the size of the gap period. A spindle for pole, bearing for another pole, measure the resistance change. After this signal processing to the optical amplifier alarm and control system, control the spindle motor start and stop, in order to avoid the friction between the shaft and bearing. |
