Selection of car tire balancer model

Due to the diversification of rotating machinery, the requirements of its vibration problems, noise problems, and mechanical life are becoming more and more stringent. It is necessary to select a dynamic balancing machine suitable for each feature for different rotating workpieces, and perform corresponding imbalance correction. The following is simple: Introduce how to choose the model.

The first step: Select the balancing machine. Firstly, according to the characteristics of the rotating workpiece, choose the horizontal or vertical balancing machine. 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 balanced rotor is horizontal on the balancing machine. Generally speaking, it has a rotating shaft or a rotor that can be equipped with a process shaft, such as a motor rotor, a machine tool spindle, a drum, a fan, a steam turbine, Turbocharger rotors, etc., are suitable for horizontal balancing machines.

Vertical balancing machine is a balancing machine in which the axis of rotation of the balanced rotor is vertical in the balancing machine. Generally refers to the disc-shaped workpieces such as gears, various automobile flywheels, clutches, pressure plates, etc., which do not have rotating shafts on the rotor itself. Assemblies, brake discs, brake hubs, motorcycle clutches and magneto rotors, fans, fan blades, pump impellers, pulleys, grinding wheels and other disc components, our company's PHD series of vertical balancing machines can meet various specifications The balance of the disc parts, and the vertical double-sided balancing machine series is suitable for the dynamic balance of the drum parts whose workpiece itself does not have a rotating shaft, such as automobile wheels, rims, centrifuge drums, etc.

The second step: According to the transmission form of the rotor, whether it is a ring belt balancing machine or a universal joint balancing machine or a self-driven balancing machine. The driving mode of the balancer dragging the rotor has a belt dragging, the coupling dragging and the coupling drive.

Belt drag - is the use of rubber ring belt or wire loop belt, drag the rotor by the motor pulley, so the belt dragging requires the rotor surface must have a smooth cylindrical surface, the advantage of the belt drag does not affect the rotor Unbalance, high balance accuracy.

Coupling drag - is the use of universal joints to connect the balancer spindle and rotor. Coupling drag is characterized by the appearance of irregular rotor, can transmit a larger torque, suitable for dragging wind turbine rotor and other large resistance, the disadvantage of coupling drag is that the joint itself will be unbalanced amount The influence of the rotor will also introduce the interference to affect the balance of the accuracy, in addition to a large number of connecting plate to adapt to different types of rotor.

Self-driving - is the use of the rotor's own power rotation. The self-driving is the dragging method that has the least influence on the balance accuracy, and the balance accuracy can be the highest, but only special rotors allowed by the structure can use this dragging method.

The third step: According to the size of the workpiece selection, such as the type of workpiece, diameter, length and weight, speed and other characteristic parameters, select the size and type of dynamic balance machine, such as 5,16,50,160 type, etc., the number represents the largest workpiece Quality, usually 1/3 to 2/3 of the selected number have good balancing effect. The maximum or minimum can be done, but it is not necessarily able to meet the accuracy of the workpiece.
