为了提高拆卸轴类紧固配合件的工作效率,保障生产的安全,我厂轮机车间的工人师傅,在兄弟厂经验的启发下,结合生产实际情况,试制成了一台可以拆卸皮带轮、齿轮、轴承等轴孔紧固配合部件的专用工具—脚踏油泵拉弓(图1)。工作原理脚踏油泵拉弓,是由脚踏约11公斤的力,连续踏在升压踏脚板8上(图2),带动活塞12在油缸内上下 In order to improve the working efficiency of the disassembly shaft fastening parts and ensure the safety of production, under the inspiration of brother factory’s experience, the factory workers of our factory are trying out a trial-and- , Bearing equiaxial hole with a special tool for fastening components - foot pump pull the bow (Figure 1). Working principle Pedal pump pull the bow, is about 11 kg of force by the pedal, step on the step-by-step stepping on the pedal 8 (Figure 2), driving the piston 12 in the cylinder up and down
