ST162高速砂轮回转机是用于检验高速砂轮的结合强度的设备,适用于砂轮制造厂的检验部门。该机采用三相可控硅直流无级调速装置,主轴最高转速可达8000转/分,砂轮回转线速度可达160米/秒。为了提高支承轴承的极限速度,采用油雾润滑,又为了减轻操作人员的劳动强度,采用气动压紧砂轮。砂轮可低速点动供调整用,当砂轮炸裂时,可由自动停车装置指示停车并断开其它系统。动力拖动系统采用连锁三角带以提高其高速运转的寿命,单片高速砂轮的外径尺寸为400～650毫米,厚度为10～200毫米,最大重量不超过50公斤。回转机在负荷高速运转以及高速爆破试验后,主轴精度一般无变化,径向振摆在0.01毫米之内,但该机在运转后其轴承温升达30℃～40℃,且存在振动和噪音大等问题,尚待进一步改进。
ST162 high-speed wheel rotary machine is used to test the bonding strength of high-speed grinding wheel equipment for grinding wheel factory inspection department. The machine uses three-phase SCR DC stepless speed control device, the maximum spindle speed up to 8000 rev / min, grinding wheel revolving line speed of up to 160 m / sec. In order to increase the limit speed of bearing support, oil mist lubrication is adopted, and in order to reduce the labor intensity of the operator, the pneumatic compression wheel is adopted. The grinding wheel can be used for adjustment at low speed. When the grinding wheel explodes, it can be stopped by the automatic parking device and disconnected from other systems. Power drag system uses a chain of triangular belt to improve its high-speed running life, single-chip high-speed wheel diameter size of 400 to 650 mm, a thickness of 10 to 200 mm, the maximum weight of not more than 50 kg. After the high-speed load operation and high-speed blasting test, the accuracy of the spindle is almost unchanged and the radial vibration is within 0.01 mm. However, the temperature of the bearing rises to 30 ° C to 40 ° C after operation, and there is vibration and noise Big issues, yet to be further improved.
