摘要
对大功率木工雕刻机电主轴进行设计,主要包括转轴轴径计算、轴承选择及其跨距的确定、预紧力的确定、润滑冷却方式的确定。对雕刻机电主轴进行出厂测试,通过对电主轴的工作温度、振动及噪声进行测试后,发现当主轴达到额定转速后各部分温度基本保持在36℃以下,振动值在1.6m/s2以下,噪音值基本在60d B左右,满足设计要求。
This paper mainly focuses on the design of high power woodworking electric spindle, including the calculation of shaft diameter, bearing selection and the determination of bearing span, pre-tightening force, lubricating and cooling mode. Through the test of working temperature, vibration and noise of electric spindle, we can find that when the spindle reaches the rated speed, the temperature of each part remain under 36℃, the vibration value below 1.6m/s^2, the basic value of the noise at around 60dB, it could meet the design requirements.
