Equipment summary:
Drive Shaft Dynamic Balancer has the characteristics of convenient operation, high balancing accuracy and low investment cost. It is ideal equipment for dynamic balance detection of automobile transmission shafts. Rotating parts such as motor rotors, machine tool spindles, fan impellers, steam turbine rotors, auto parts and air-conditioning blades all need to be balanced to operate smoothly and normally during the manufacturing process. Correcting the unbalance of the rotor according to the data measured by the balancing machine can improve the mass distribution of the rotor relative to the axis, and reduce the vibration generated when the rotor rotates or the vibration force acting on the bearing within the allowable range. Therefore, balancing machines are essential equipment for reducing vibration, improving performance and improving quality.
Working principle:
A balancing machine is a machine that measures the size and position of the unbalance of a rotating object (rotor). Centrifugal forces are generated by the uneven distribution of mass relative to the axis as the rotor rotates around its axis. The unbalanced centrifugal force acting on the rotor bearing will cause vibration, generate noise and accelerate bearing wear, which will seriously affect the performance and life of the product. Therefore, a balancing machine should be used for testing.
Usually, the balance of the rotor includes two steps of unbalance measurement and correction. The balancing machine is mainly used for the measurement of unbalance. The main performance of the balancing machine is expressed by two comprehensive indicators, the minimum reachable residual unbalance and the unbalance reduction rate. The former is the minimum value of the residual unbalance that the balancing machine can make the rotor reach, and it is an index to measure the highest balancing ability of the balancing machine; the latter is the ratio of the unbalanced amount reduced to the initial unbalanced amount after one correction, which is a measure of the balancing efficiency. indicators, generally expressed as a percentage.
