Basic Principles of Dynamic Balance

This unbalanced centrifugal force on the rotor bearing will cause oscillation, noise and accelerated bearing wear, resulting in serious impact on the function and life of the product. Motor rotor, machine tool spindle, internal combustion engine crankshaft, steam turbine rotor, gyro rotor and watch balance wheel and other rotating parts in the manufacturing process, all need to be balanced to run smoothly and normally. According to the balance machine measured data on the unbalance of the rotor to proofread, can improve the mass distribution of the rotor relative to the axis, the rotor rotation occurs when the oscillation or the oscillation force on the bearing is reduced to the scale allowed. 

Therefore, the balancing machine is to reduce the vibration, improve the function and improve the quality of the essential equipment. Usually, the balance of the rotor contains two processes of unbalance measurement and proofreading. The balancing machine is mainly used for measurement of unbalance, and the proofreading of unbalance is often assisted by drilling machine, milling machine and spot welder and other auxiliary equipment, or the end of manual method. Some balancing machine has been proofreading device to become a part of the balancing machine. Gravity balancing machine and centrifugal balancing machine is two types of typical balancing machine. Gravity balancing machine is generally called static balancing machine. It depends on the gravity of the rotor itself to measure the static unbalance.
