Relationship between the power or torque and the rotational speed of the spindle transmission. When the machine is in continuous operation, the spindle speed in the 437 ~ 3500r / min range, deliver full power 11kW spindle motor spindle constant power region Ⅱ (solid line). In this region, Jiaxing electric spindle production, spindle maximum output torque (245N.m) With the spindle speed increases and decreases. Spindle speed in the 35 ~ 437r / min range Jiaxing electric spindle supply, the output shaft of the torque constant, constant torque region called spindle Ⅰ (solid line). In this region, the spindle can transfer power with the decrease of the spindle rotation speed decreases. Thermal and dynamic characteristics of electric spindle cooling due to electric spindle motor integrated in the spindle unit, and the speed is high, it will generate a lot of heat Jiaxing Spindle company is running, the temperature rise caused by electric spindle spindle, spindle make change poor, thus affecting the normal operation of electric spindle. Therefore, we must take certain measures to control spindle temperature to a constant within a certain value. The general machine cycle oil cooling coercive manner spindle and spindle bearing stator cooling oil cooling oil is about to go through a mandatory cooling device outside the stator in the spindle and spindle bearing outer loop, take away the heat generated by high speed rotation of the spindle .
