目前,国内各个木工机械厂所生产的平刨、压刨以及多面刨床的噪声都很大.切削刀轴都是圆柱体,并在刀轴上开有不同数量的镶刀片用槽沟,刀轴切削木材时旋转速度很高,一般在4500～6000转/分.国内使用的刨刀轴结构,其刀轴槽口很大,在刀轴高速旋转时迫使空气流随刀轴作高速同步运动,并且一部分空气流沿刀轴旋转切线方向飞出,碰着障碍物反射回到刀轴上,产生涡流气流,空气流处在一种复杂的运动状态中.因此刀轴高速旋转是引起噪声的根本原因.其次,刀轴动力不平衡以及三角带轮偏心,
At present, the planer, planer and multi-face planer produced by all woodworking machinery factories in our country have a lot of noise.The cutting axles are all cylinders, and there are different numbers of inserts with slots on the axles, Cutting wood when the rotation speed is high, usually 4500 ~ 6000 rev / min. Planer axis structure used in China, the knife shaft notch large, the blade shaft at high speed rotation to force air flow with the knife shaft for high-speed synchronous movement, and Part of the air flow along the blade axis tangential direction of flight, hit the obstacle reflected back to the knife shaft, resulting in eddy current, air flow in a complex state of motion. Therefore, shaft speed is the root causes of noise Second, the unbalanced power of the cutter shaft and the eccentricity of the triangular pulley,
