几乎所有斗轮挖掘机的斗轮在水平面内均有一偏角α,某些斗轮在垂直面内还另有一倾角β(图1)。偏角与倾角的作用是,使物料便于卸到运输胶带上,增大了胶带一侧斗轮的自由切削角,减小了挖掘阻力对斗轮臂产生的扭矩。本文拟就上述两个角度对斗轮挖掘机的影响作简要分析。 Almost all bucket wheel excavators have a declination angle α in the horizontal plane, and some bucket wheels have another inclination β in the vertical plane (Fig. 1). The role of declination and inclination is to make the material easy to be unloaded on the transport tape, increase the free-cutting angle of the bucket wheel on the side of the tape, and reduce the torque generated by the excavating resistance on the bucket arm. This article will briefly analyze the impact of the above two angles on the bucket wheel excavator.
