What is the importance of balancing machine in modern machinery
In modern machinery, due to the wide application of flexible rotors, flexible rotor balancing machines have been developed. This balancing machine has to be steplessly regulated within the working speed range of the rotor; in addition to measuring the vibration or vibration force of the support, it can also measure the deflection of the rotor. Flexible rotor balancing machines are sometimes installed in vacuum protection chambers to accommodate the balancing of steam turbines and other rotors. It is equipped with a large number of auxiliary equipment such as vacuum pump system, lubrication system, lubricating oil degassing system and computer system for data processing. A balancing machine is a machine used to measure the size and position of the unbalance of a rotating object (rotor).
When any rotor rotates about its axis, centrifugal force is created due to the uneven distribution of mass relative to that axis. such injustice
Centrifugal forces on balance rotor bearings can cause vibration, noise and accelerated bearing wear, which can seriously affect product performance and service life. During the manufacturing process, rotating parts such as motor rotors, machine tool spindles, internal combustion engine crankshafts, turbine rotors, gyro rotors, clocks and balance wheels need to be balanced for smooth and normal operation.
Generally, rotor balancing involves two steps: unbalance measurement and correction. The balancing machine is mainly used for the measurement of unbalance, and the correction of unbalance is usually carried out by drilling machines, milling machines, spot welding machines and other auxiliary equipment, and can also be carried out manually. Some balancing machines make the correction device part of the balancing machine.
According to the data measured by the balancing machine, the unbalance of the rotor can be corrected, which can improve the mass distribution of the rotor relative to the axis and reduce the vibration or vibration force acting on the bearing to the allowable range. Therefore, the balancing machine is an indispensable equipment for reducing vibration, improving performance and improving quality.
