一、前言 我国近十余年来,自行设计、制造并投产了一些大型氧气顶吹转炉。由于这种转炉冶炼周期短、生产率高、负载大等特点,要求其机械设备应具有很高的运转率、优良的设备性能和运转安全可靠。对于作为主体机械设备之一的倾动机构传动系统的要求就更应如此。冶金设备工作者显然期望在一座新 I. Introduction In the past decade or so, China has designed, manufactured and put into production some large-scale oxygen top-blown converters. Because of this converter smelting cycle is short, high productivity, load and other characteristics require its machinery and equipment should have a high rate of operation, excellent equipment performance and safe operation. This is even more so with the requirement of a tilting mechanism transmission as one of the main mechanical devices. Metallurgical equipment workers obviously expect a new one
