How Does The Balancing Machine Measure?

The balancing machine is a machine that measures the size and position of unbalanced rotating objects. When the rotor rotates around its axis, the centrifugal force is generated due to the uneven distribution of the mass distribution with respect to the axis. This unbalanced centrifugal force acts on the rotor bearings to cause vibration, noise and accelerated bearing wear, which seriously affects the performance and longevity of the product.

Rotary parts such as motor rotor, machine tool spindle, internal combustion engine crankshaft, steam turbine rotor, gyro rotor and watch wheel and so on are all need to be balanced to run normally. The correction of the unbalance of the rotor is made according to the data measured by the balancing machine to improve the mass distribution of the rotor relative to the axis so that the vibration generated during the rotation of the rotor or the vibration force acting on the bearing is reduced to within the allowable range. Therefore, the balancing machine is an indispensable device for reducing vibration, improving performance and improving quality.

Usually the balance of the rotor includes two steps of measurement and correction of the unbalance, which is mainly used for the measurement of unbalance, and the correction of the unbalance is often done by means of other auxiliary equipment such as drilling machines, milling machines and spot welding machines or by hand The Some balancing machines have made the calibration device a part of the balancing machine. Gravity Balancing Machines and Centrifugal Balancing Machines are two typical balancing machines. Gravity balancing machines are commonly known as static balancing machines. It is dependent on the rotor's own gravity to measure static imbalance. If the rotor on the two horizontal rails is unbalanced, its heavy moment on the axis causes the rotor to roll on the rail until the unbalance is at its lowest position.
