(Summary description)The driving mode of the balancing machine to drag the rotor includes ring and belt drag, coupling drag and self-driving. Ring belt drag is to use rubber ring belt or silk woven ring belt, the rotor is driven by the motor pulley. Therefore, ring belt drag requires the rotor surface to have a smooth cylindrical surface. The advantage of ring belt drag is that it does not affect the imbalance of the rotor. , High balance accuracy.   Coupling drag is the use of universal joints to connect the main shaft of the balancing machine with the rotor. The characteristic of coupling drag is that it is suitable for rotors with irregular appearance, can transmit larger torque, and is suitable for dragging rotors with large wind resistance such as fans. The disadvantage of coupling drag is that the unbalance of the coupling itself will affect The rotor has an impact (so the coupling must be balanced before use). Interference will also be introduced to affect the accuracy of the balance. In addition, a large number of connecting plates must be made to adapt to different types of rotors. Self-driving uses the power of the rotor to rotate. Self-driving is the drag mode that has the least impact on the balance accuracy, and the balance accuracy can reach the highest, but only special rotors allowed by the structure can use this drag mode. The balancing machine is a machine that measures the size and position of the unbalance of a rotating object (rotor). When the rotor rotates around its axis, centrifugal force is generated due to the uneven mass distribution relative to the axis. This kind of unbalanced centrifugal force acting on the rotor bearing will cause vibration, generate noise and accelerate bearing wear, which will seriously affect the performance and life of the product. Therefore, a balance machine must be used for testing.
