检验扭矩和轴向力的相位脉冲式预防装置,由于采用感应式传感器,因之具有较高的灵敏度,传感器与借弹性元件连接的齿轮的齿相互作用。预防装置安装在主轴上,消除转动惯量和摩擦损失的影响。 相位脉冲式的预防装置设计成几种方案,取决于钻削直径、工件的夹紧方式等。这种型式的装置示于图1,它能消除主轴转动惯量的影响,用于加工直径10毫米以下的深孔钻床上。齿轮1紧固在主轴上,主轴轴承2、3和16上装着预防装置的主轴4、承载齿轮5和扭力杆6,法兰盘7联接扭力杆与主运动传动装置的皮带轮8。用法兰盘7来
The phase-pulse preventive device for checking torque and axial force, due to the use of an inductive sensor, has a high degree of sensitivity and interacts with the teeth of the gear connected by the elastic element. Preventive devices are mounted on the spindle to eliminate the effects of moment of inertia and friction loss. Phase pulse prevention device designed into several programs, depending on the drilling diameter, workpiece clamping and so on. This type of device, shown in Figure 1, eliminates the effects of the spindle’s moment of inertia and is used to machine deep-hole drills up to 10 mm in diameter. The gear 1 is fastened to the main shaft, the main shaft bearings 2, 3 and 16 are mounted on the main shaft 4 of the preventive device, the carrier gear 5 and the torsion bar 6, and the flange 7 is connected with the torsion bar and the pulley 8 of the main motion transmission. Use flange 7 to come
