BEL 动力头为滑套式电气机械驱动动力头,主要为单轴使用,也可附加多轴箱。电动机为顶置,经三角皮带减速,传动主轴回转。进给运动系统由主电动机用链传动, 快进、快退、工作进给用两个电磁离合器和两个制动器变换接通和制动来实现。图1为其外观图。动力头箱体内的减速齿轮全部在油内运转。容许最大钻孔直径为φ30(在δ_b=60公斤/厘米~2的钢上),最大钻孔行程为120毫米,采用输出功率为5.5瓩的
BEL power head for the sliding sleeve electric mechanical drive power head, mainly for single-axis use, but also additional multi-axis box. The motor is overhead, decelerated by V-belt, transmission spindle rotation. Feed motion system by the main motor with chain drive, fast forward, rewind, work feed with two electromagnetic clutches and two brakes to change the connection and braking to achieve. Figure 1 is its appearance. The reduction gear in the power headbox is all running in the oil. Allowable maximum drilling diameter φ30 (in δ_b = 60 kg / cm ~ 2 of steel), the maximum drilling stroke of 120 mm, the output power of 5.5 瓩
