Selection of car tire balance machine model

Due to the diversification of rotating machinery, the requirements for vibration, noise, mechanical life, etc. have become increasingly stringent. It is necessary to select a dynamic balancing machine suitable for their characteristics for different rotating workpieces, and perform corresponding imbalance corrections. The following is simple Introduce how to choose a model.
**Step: To choose a dynamic balancing machine, first select 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, a steam turbine, Supercharger rotors, 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 the disc-shaped workpieces such as gears, various automobile flywheels, clutches, pressure plates and the like that do not have a rotating shaft. Assemblies, brake discs, brake hubs, motorcycle clutches and magneto rotors, fans, fan blades, water pump impellers, pulleys, grinding wheels and other disc parts, the PHD series of vertical balancing machines produced by our company can meet various specifications The vertical double-sided balancing machine series is suitable for the dynamic balancing of drum-shaped parts that do not have a shaft, such as automobile 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. drive.
Ring belt drag-the use of rubber ring belt or silk woven ring belt, the motor pulley is used to drive the rotor, so ring belt drag requires the rotor surface must have a smooth cylindrical surface, the advantage of ring belt drag is that it does not affect the rotor The amount of unbalance, the balance precision is high.
Coupling dragging-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, 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 the use of the rotor’s own power to rotate. Self-driving is a drag mode that has the smallest 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, such as the type of workpiece, outer diameter, length and weight, speed and other characteristic parameters, select the size and model of the dynamic balancing machine, such as 5, 16, 50, 160, etc., the number indicates the workpiece* For large quality, generally selecting the number 1/3 to 2/3 has better dynamic balance effect, and the maximum or minimum value can be used, but it may not meet the accuracy of the workpiece.
