造成破碎机被迫振动的原因都有哪些呢?

  圆锥破碎机是一种重要的大型选矿设备。在其运行过程中,部件的磨损将严重影响破碎机振动的稳定性,并使机器长期处于强迫振动状态,严重影响破碎机的安全运行。研究发现,扰动力是影响破碎机强迫振动的重要因素。
  Cone crusher is an important large-scale mineral processing equipment. In its operation process, the wear of components will seriously affect the stability of the vibration of the crusher, and make the machine in a forced vibration state for a long time, seriously affecting the safe operation of the crusher. It is found that the disturbing force is an important factor affecting the forced vibration of the crusher.
  根据圆锥破碎机的角速度矢量图,由于圆锥破碎机的结构特点支持设备,圆锥破碎机不仅旋转的偏心孔偏心轴套线的机器,而且绕自己的轴旋转。这种破碎机圆锥的运动称为规则运动。由于断锥的质心不在其旋转线上,在操作过程中必须产生惯性力和惯性矩。作用在车架上的力是周期性的动载荷,它引起车架的振动和偏心套筒的偏转。当破碎机在正常运行时,在空载情况下对机架套筒和球面轴承产生周期性的反力变化,导致机架有害振动和偏心轴套偏转而不能正常工作。

  According to the angular velocity vector diagram of the cone crusher, because of the structural characteristics of the cone crusher supporting equipment, the cone crusher not only rotates the machine of the eccentric hole eccentric shaft sleeve centerline, but also rotates around its own axis. The movement of the crusher cone is called regular movement. Because the center of mass of the broken cone is not on its rotation center line, inertia force and moment of inertia must be produced in the operation process. The force acting on the frame is periodic dynamic load, which causes the frame vibration and deflection of eccentric sleeve. When the crusher is in normal operation, under no-load condition, it will produce periodic counter force changes to the sleeve and spherical bearing of the frame, which will cause harmful vibration of the frame and deflection of the eccentric sleeve, so it can not work normally.
  在圆锥破碎机锥齿轮上增加配重是为了消除由于圆锥方向改变而产生的惯性力和惯性力矩。由于破碎机结构尺寸的限制,不能完全消除破碎机圆锥的惯性力,因此破碎机圆锥的旋转会产生较大的不平衡惯性力,这是造成破碎机框架和基础振动的扰动力。即破碎机的扰动力是破碎机圆锥围绕轴旋转时产生的不平衡惯性力。扰动力下的振动分析。根据振动的原因,破碎机的振动可分为自由振动和强迫振动,破碎机的机体和地基由于外界的连续振动,在振动的整个过程中总会有一个扰动力,这是一种典型的强迫振动。
  The purpose of adding counterweight to bevel gear of cone crusher is to eliminate the inertia force and moment caused by the change of cone direction. Due to the limitation of the crusher structure size, the inertia force of the crusher cone cannot be completely eliminated, so the rotation of the crusher cone will produce a large imbalance inertia force, which is the disturbing force that causes the vibration of the crusher frame and foundation. That is to say, the disturbing force of crusher is the unbalanced inertia force produced when the cone of crusher rotates around the central axis. Vibration analysis under disturbing force. According to the reason of vibration, the vibration of crusher can be divided into free vibration and forced vibration. Due to the continuous vibration of the outside world, there will always be a disturbing force in the whole process of vibration, which is a typical forced vibration.
