我厂广大革命职工发扬敢想敢干的革命精神,自力更生,群策群力,只用半年多时间,就自行设计和制造了一台1.5米立式万能磨床,为生产外径1.5米以下的特大型轴承创造了有利条件,同时也为今后自制特大型磨床提供了有益的经验.该磨床的特点是:床身采用钢板焊接结构,左右立柱固定在床身上.横梁为锒嵌铸铁导轨的钢板焊接结构.工作台采用特大型推力滚子轴承及双列向心短圆柱滚子轴承作支承.台面由5.5千瓦直流电动机驱动,采用可控硅无级变速,调速范围为2～60转/分.根据轴承外径大而宽度小的特点,横梁固定在立柱上,而由磨轴架调整磨削位置的高低,最大行程为600毫米,工作台面上装置
Our revolutionary workers carry forward the spirit of daring to dare to do the revolution, self-reliance, team work, only half a year’s time, we designed and manufactured a 1.5 m vertical universal grinder, for the production of large diameter bearings below 1.5 meters Creating favorable conditions, but also for the future self-made extra large grinder provides useful experience.The grinder is characterized by: bed with welded steel structure, left and right columns fixed to the bed.Transverse cast iron rail with welded steel plate structure. The workbench is supported by extra-large thrust roller bearings and double row radial short cylindrical roller bearings.The tabletop is driven by a 5.5 kW DC motor and adopts a continuously variable speed controllable silicon-based silicon carbide silicon carbide silicon carbide with a speed range of 2 to 60 rpm. Bearings large diameter and small width of the characteristics of the beam fixed to the column, and the grinder-axis adjustment of the grinding position of the high and low, the maximum travel of 600 mm, the work surface device
