我公司新三轧热轧厂从日本引进的KWA-1060 B型轧辊磨床,投产使用一年后因设备事故,使静压轴承套研坏。为了修复该机床,需要更换新的轴承套。经过我们反复摸索试验,终于制造出了完全符合图纸要求的轴承套,节约了大量外汇,及时满足了热轧厂的生产需要。轴承套如图1所示,油腔是矩形的,四个油腔中间凸起,凸起两边及上下成凹形,要求油腔既要对称,面积又要相等。油腔长度超过X52K的行程范围,按一般方法不能加工。我们采用的是两头
The new three rolling hot rolling mill imported from Japan KWA-1060 B-type roll grinder, put into operation one year after the accident due to equipment, so that static pressure bearing sets of bad research. In order to repair the machine, you need to replace the new bearing sleeve. After repeated trial and error tests, we finally produced a bearing sleeve that fully meets the requirements of drawings, saving a large amount of foreign exchange and meeting the production needs of the hot-rolling mill in time. Bearing sleeve shown in Figure 1, the oil chamber is rectangular, four oil chamber in the middle of the bulge, raised on both sides and up and down into a concave, requires the oil chamber should be symmetrical, the area has to be equal. Oil chamber length exceeds the travel range of X52K, according to the general method can not be processed. We use two ends
