Characteristics and Applications of Motor Balancing Machines
The motor balancing machine adopts a ring belt drive, ensuring the balance quality and accuracy of the workpiece, and has the characteristics of easy loading and unloading, fast start-up, and high work efficiency.
Motor balancing machines are widely used for balancing and correcting rotating workpieces such as rotors, impellers, crankshafts, drums, and shafts in various small and medium-sized motors.
The transmission methods for dragging the rotor of a balancing machine include belt drive, coupling drive, and self drive.
Ring belt dragging is the use of rubber or silk ring belts to drive the rotor by the motor pulley. Therefore, ring belt dragging requires a smooth cylindrical surface on the rotor surface. The advantage of ring belt dragging is that it does not affect the unbalance of the rotor and has high balance accuracy.
Coupling drag is the use of universal joints to connect the main shaft and rotor of a balancing machine. The characteristic of coupling drag is that it is suitable for rotors with irregular appearances, can transmit large torque, and is suitable for dragging rotors with high wind resistance such as fans. The disadvantage of coupling drag is that the imbalance of the coupling itself will affect the rotor (so it needs to be balanced before use), and it will also introduce interference that affects the accuracy of balance. In addition, a large number of connecting discs need to be made to adapt to different types of rotors.
