磨床的砂轮架是床子的关键部件,而砂轮运转精度,刚度,振动的性能主要决定于砂轮主轴的支承。我厂所生产的M120W万能外圆磨床的砂轮主轴,由两副油膜轴承支承,每副轴承包括三块钢套镶铜的轴瓦,短三块式轴承适用于高速旋转的主轴,对于轴瓦加工工艺已经掌握,并根据生产的具体条件,自制了几种加工轴承的专用设备。图1为M120W轴瓦。轴瓦材料原为20铜、铅、银合金,现用材料是铸铅青铜,牌号为ZQPb30,其制造工艺
Grinder wheel frame is a key component of the bed, and wheel running accuracy, stiffness, vibration performance is mainly determined by the wheel spindle support. The M120W Universal Cylindrical Grinder Grinding Wheel spindle produced by our factory is supported by two oil film bearings. Each pair of bearings includes three steel bushings with copper sleeves. The short three-piece bearing is suitable for high-speed rotating spindle. Has been mastered, and according to the specific conditions of production, made several kinds of processing bearing special equipment. Figure 1 for the M120W bearing. Bearing material was originally 20 copper, lead, silver alloy, the current material is cast lead bronze, grade ZQPb30, its manufacturing process
