Instructions and functions of the dynamic balancing machine
Dynamic balancing machine instructions:
It is known from Newton's law of motion that any object rotating at a constant speed will rotate centrifugally inertial force, which is called centrifugal force, disk rotor, and the rotor rotates at an angular velocity ω. Any mass in the rotor will be When the centrifugal force F occurs, the centrifugal force F=mrω2, which is composed of an inertial force acting on the bearing, constitutes the dynamic pressure of the rotor to the bearing, and its size is determined by the dispersion of the rotor mass. If the mass of the rotor is symmetrically distributed to the axis of rotation, the dynamic pressure is zero, that is, the centrifugal forces of the masses are balanced with each other. Otherwise, dynamic pressure will occur, especially at high speeds. Therefore, it is necessary to perform dynamic balance correction on the rotating body, particularly the high-speed rotating body, which is the principle of the dynamic balancing machine.
The working principle of different types of dynamic balancing machines is the same, and the specific operation can be carried out according to the instructions. The general process is: first, the workpiece should be placed on the balance machine for balance test, then the balance will show the magnitude and angle of the workpiece imbalance, and then the workpiece will be weighted or de-duplicated according to the specific requirements of the workpiece. The weight that is up or subtracted is the amount of imbalance displayed on the balancer.
In daily industrial machinery, there are a large number of rotating motion components, dynamic balancing machine spindles and turbine rotors. Ideally, when rotating and not rotating, the pressure on the bearing is the same, which is the balance. However, in practical applications, due to uneven material or blank defects, errors in processing and assembly, and even asymmetric geometric shapes when designing, the centrifugal inertia generated by each tiny particle cannot be mutually rotated. Offset, the centrifugal inertial force acts on the machine and its foundation through the bearing, causing vibration, generating noise, accelerating bearing wear, shortening the mechanical life, and causing destructive accidents when severe. To this end, it is necessary to balance the pressure level to a specified level of balance accuracy or to reduce the amplitude of the generated mechanical vibration within a specified range.
