我厂生产的MB 1520、MB 1620、MB 1720高效率半自动切入式外圆磨床,为了满足机床宽砂轮、高效率切入磨削的特点,在砂轮架轴承上采用了液体静压轴承。静压轴承采用的是小孔节流形式,我们主要考虑的是砂轮主轴转速较高,磨擦力大,使用粘度大的油会产生较高的温升。采用小孔节流可用粘度低的油,流量虽大些,散热却较好。 I plant the MB 1520, MB 1620, MB 1720 high efficiency semi-automatic entry cylindrical grinder, in order to meet the machine wide grinding wheel, high-efficiency cutting into the grinding characteristics of the wheel bearing on the use of hydrostatic bearings. The hydrostatic bearing is a small orifice throttling form, our main consideration is the high spindle speed grinding wheel, friction, the use of large viscosity oil will have a higher temperature rise. The use of small holes can be used to reduce the viscosity of the oil flow, although the larger flow, cooling is better.
