Due to the diversification of rotating machinery, the requirements for vibration problems, noise problems, mechanical life, etc. are becoming increasingly stringent. It is necessary to select dynamics suitable for their characteristics for different rotating workpieces.Balancing machine, And carry out the corresponding imbalance correction, the following briefly introduces how to choose the model.
Step 1: Choose a dynamic balancing machine. First, choose a horizontal or vertical dynamic balancing machine according to the shape characteristics of the rotating workpiece. Of course, if there are special requirements, it can also be designed and manufactured according to actual needs.
Horizontal balancing machine-is a balancing machine in which the axis of rotation of the rotor to be balanced is horizontal on the balancing machine. Generally speaking, a rotor with a rotating shaft or a process shaft that can be assembled, such as a motor rotor, a machine tool spindle, a drum, a fan, Steam turbine,SuperchargerRotors, etc., are all suitable for horizontal balancing machines.
Vertical balancing machine-is a balancing machine in which the axis of rotation of the rotor to be balanced is in a vertical state on the balancing machine. Generally, it refers to disc-shaped workpieces such as gears and variouscarflywheel,clutch, Pressure plate and its assembly, brake disc,brakeHubs, motorcycle clutches and magneto rotors,fan, Fengye,Water pumpimpeller,beltFor disc parts such as wheels and grinding wheels, the PHD series vertical balancer produced by our company can meet the balance of disc parts of various specifications, while the vertical double-sided balancer series are suitable f

Dynamic balance, such as car wheels, rims, centrifuge drums, etc.
The second step: According to the transmission form of the rotor, choose whether it is a ring belt drive balancer, a universal joint balancer or a self-driving balancer. The transmission mode of the balancer to drive the rotor includes ring belt drag, coupling drag and self-driving balancer. drive.
Ring belt drag ---- is the use of rubber ring belt or silk woven ring belt, the rotor is driven by the motor pulley, so the ring belt drag requires the rotor surface to have a smooth cylindrical surface. The advantage of the ring belt drag is that it does not affect The unbalanced amount of the rotor has high balance accuracy.
Coupling drag ---- is the use of universal joints to connect the main shaft of the balancer 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), and interference will also be introduced to affect the accuracy of the balance. In addition, a large number of connecting disks must be made to adapt to different types of rotors.
Self-driving ---- is to use 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 third step: according to the size of the workpiece selection, such as the type of workpiece, outer diameter, length and weight,Rotating speedAnd other characteristic parameters, select the size and model of the dynamic balancing machine, such as 5, 16, 50, 160, etc., the number indicates the maximum quality of the workpiece, generally selecting the number 1/3 to 2/3 has a better dynamic balance effect, and the maximum or minimum value is both It can be done, but it may not meet the accuracy of the workpiece.
