The motor balancing machine adopts a ring belt drive to ensure the balance quality and accuracy of the workpiece, and has the characteristics of easy loading and unloading, fast start, and high work efficiency.
Motor balancing machines are widely used for balancing and correcting rotating workpieces such as rotors, impellers, crankshafts, drums, and shafts of various small and medium-sized motors.
The transmission methods for balancing machine to drive the rotor include ring belt drive, coupling drive, and self drive.
Ring and belt dragging is the use of rubber or silk woven ring belts to drive the rotor by the motor pulley. Therefore, ring and belt dragging requires a smooth cylindrical surface on the rotor surface. The advantage of ring and belt dragging is that it does not affect the rotor's imbalance and has high balance accuracy.
Coupling drag is the use of a universal joint to connect the balance machine spindle with the rotor. 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 can affect the rotor (therefore, 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 plates need to be made to adapt to different types of rotors.
