introduction：There are two main kinds of vibration motors for vibrating screen，Vertical vibration motor is mainly used in rotary vibration screen，The horizontal vibration motor can be applied to all kinds of vibration screening equipment，The vibrating motor is the most important vibration source of the vibrating screen，Its importance can be imagined。Vibration motor selection of heavyKOYObearing，Can bear a certain axial load，Regardless of mounting orientation，KOYOBearing life is not affected by axial load force。 1.Break downKOYObearing （1）Remove the protective covers at both ends of the vibration motor（Vertical vibration motor without protective cover），Record the centenary value of the excitation force of the eccentric block when it is working，So that it can be restored during installation
