Do you know the classification of the balancing machine?

Balancing machine is to improve the quality of the rotor and its components; reduce noise; reduce vibration; improve the service life of the supporting parts (bearings); equipment used to measure the rotor imbalance, because there is unbalanced centrifugal force on the rotor, it will definitely Causes vibration of the rotor itself or the main parts of the product.

The main function of the balancing machine is to measure, and sometimes with correction devices to improve product quality.

First, the classification of the balance machine:
Although there are many types of balancing machines, we can divide them by working principle and product application.

A, from the principle points: there are centrifugal balance machine and gravity balance machine; soft support balance machine; hard support balance machine.
1. Centrifugal and gravity balancing machine
Centrifugal balancing machine: From the structural principle of the balancing machine, the most common one is the centrifugal balancing machine, which measures the unbalanced balance according to the supporting vibration caused by the rotor imbalance in the rotating state or the vibration force acting on the support. machine. According to the number of calibration planes, it can be divided into single-sided balancing machine and double-sided balancing machine. A single-sided balancing machine can only measure the amount of imbalance on one plane (static imbalance). Although it is measured while the rotor is rotating, it still belongs to the static balance machine. The double-sided balance machine can measure dynamic imbalance, static imbalance and even imbalance. Usually called a dynamic balancing machine.

Gravity balance machine: Gravity balance machine is generally called static balance machine. It relies on the gravity of the rotor itself to measure static imbalance. If the rotor placed on the two horizontal rails has an unbalanced amount, its heavy moment against the axis causes the rotor to roll on the guide rail until the unbalanced amount is at the lowest position. This type of balancing machine does not need to rotate the workpiece during measurement. It is especially suitable for balancing workpieces and large disk parts that are deformed during rotation, such as unsintered grinding wheels, train wheel brake discs, aircraft propellers, aviation tires, etc.

2. Soft support balance machine, hard support balance machine
Soft bearing balance machine: The soft support balancer has a soft swing and high measurement accuracy. During the start and stop of the drive shaft, the soft support swing will have very obvious vibration, and the hard support swing will not have this. a phenomenon.
Hard bearing balance machine: The balance speed is lower than the solid frequency of the rotor-support system, which can be balanced at low speed. No need for locking device, it can be tested for overspeed, easy to operate and safe.

B. From the application point of view:
There are horizontal balancing machine and vertical balancing machine; universal balancing machine and special balancing machine.

1. Horizontal balance machine and vertical balance machine
The horizontal balancing machine is a balancing machine that is horizontally balanced on the balancing machine by the axis of rotation of the balancing rotor. Generally, a rotor with a rotating shaft or a process shaft can be assembled, such as a motor rotor, a machine tool spindle, a drum, a fan, a steam turbine, and a supercharger. The device is suitable for horizontal balancing machines.
The vertical balancing machine is a balancing machine that is vertically inclined on the balancing machine by the axis of rotation of the balancing rotor. Generally speaking, the disk itself has a disk-shaped workpiece without a rotating shaft such as a gear, various automobile flywheels, a clutch, a pressure plate and an assembly thereof. Brake discs, brake hubs, clutches for motorcycles and magneto-motor rotors, fans, blades, pump impellers, pulleys, grinding wheels, etc.

2. Universal balancing machine and special balancing machine
The universal balancing machine is a balancing machine that balances multiple rotors within the specified rotor weight and speed range.
The special balancing machine is a balancing machine that balances a certain type of rotor within the specified rotor weight and speed range.
