在牙轮钻机的回转器传动中,由可控硅变流器供电的直流电动机得到了广泛应用。例如,在СБШ型钻机的回转器上就是采用ДВП-52型直流电动机拖动的。对回转电动机来说,不象挖掘机传动那样对过渡过程要求严格,它应当简单,可靠并满足重量和尺寸比例关系,以使回转加压机构紧凑、使用方便。回转器广泛采用直流电动机传动,这说明对交流拖动有些轻视。应当指出,在钻机系统中,采用对回转传动速度的附加控制(除了控制对炮孔孔底的轴压力外)不能认为总是合适的。工作速度大小取决于许用的工艺参数,并且在不出现振动情况下使回转转速保持在能获得最高生产效率的水平上是合理的。当开孔以及发生强烈振动时要降低转速。为了解决这些问题可以调整加压,改变电机机械特性的斜率或采用不用调整的软特性电机。这可由钻机质
In the rotary gear drive cone drill, by the silicon controlled rectifier DC motor power supply has been widely used. For example, the ДВП-52 DC motor is used on the rotors of the СБШ rig. For swing motors, unlike the excavator drive, which imposes a strict transition process, it should be simple, reliable and meet the weight and size ratio to make the rotary press mechanism compact and easy to use. Rotor widely used DC motor drive, indicating that the AC drag some contempt. It should be noted that in rig systems, it is not always appropriate to apply additional control over slewing gear speed, other than controlling the shaft pressure to the bottom of the borehole. The speed of operation depends on the allowable process parameters and it is reasonable to keep the revolving speed at the highest productivity without vibration. Reduce speed when drilling holes and strong vibrations. In order to solve these problems, it is possible to adjust the pressurization, change the slope of the mechanical characteristics of the motor, or adopt a soft-characteristic motor without adjustment. This can be boring machine quality
