现代化重型机床负重范围(最大负载与最小负载之比)不断地增大,如加工直径6300—25000毫米的单柱立车系列,当工作台负载达到10MH(1000吨)时,系列负载范围为10,因此,常用的一些静压系统,不能保持油膜厚度的稳定。 油腔压力反馈调节器系统是有效的静压导轨系统,它可根据油压的大小自动调节流量。该调节器(图略,下同)装有弹簧圈,圈上开有径向槽,靠挡块控制其自转,弹簧圈装在偏心轮上,使其外表面与调节器体孔之间形成高度为h=(d-d_1)/2=0.2-1毫米的间隙,藉以调节流量的阻尼。由于弹簧圈端面有10—15微米的缝隙,所以可在缝隙范围内
The weight range of modern heavy machine tools (the ratio of the maximum load to the minimum load) continues to grow. For example, the single-column vertical lathe with a diameter of 6300-25000 mm is processed. When the load of the working table reaches 10MH (1000 tons), the series load range is 10 , Therefore, some commonly used static pressure system, can not maintain the stability of the film thickness. Oil pressure feedback regulator system is an effective hydrostatic guide rail system, it can automatically adjust the flow rate according to the size of the oil pressure. The regulator (figure omitted, the same below) is equipped with a spring ring, the ring is provided with a radial groove, by the stopper to control its rotation, the spring ring is mounted on the eccentric wheel so that the outer surface of the regulator body formed between the hole The height is h = (d-d_1) /2=0.2-1 mm clearance, in order to adjust the flow damping. Due to the 10-15 micron coil end face of the gap, it can be within the gap
