Description

technical field [0001] The invention relates to the technical field of devices for testing the vibration of fan blades, in particular to a single-sided dynamic balancing machine for fan blades. Background technique [0002] A dynamic balancing machine is a machine that measures the size and position of the unbalance of the fan blades of the product. As the fan blade rotates around its axis, centrifugal force is generated due to the uneven distribution of mass relative to the axis. This unbalanced centrifugal force will cause vibration on the blade bearing, generate noise and accelerate bearing wear, which will seriously affect the performance and life of the product. Therefore, a dynamic balancing machine is used to test the quality of the product. [0003] The existing fan blade dynamic balancing machine uses a matching electric motor to drive the fan blade. The speed of the fan blade is controlled and adjusted by changing the voltage of the power supply. Reflect the unba...

AI Technical Summary

Problems solved by technology

[0004] Different types of fan blades must be installed with different matching stator motors, which is time-consuming and troublesome to replace, and increases production costs; 2. The imbalance of the stator motor itself will affect the unbalance of the fan blades, increasing errors and reducing quality; 3. Manual adjustment is required The output of the power supply voltage is used to achieve the required speed of the test, and the efficiency is low. Some fan blades have no star spots or the star spots are not polished enough. It is necessary to paste photosensitive paper to detect the speed, which affects production efficiency, and the quality of the photosensitive paper itself will directly affect the fan blades. 4. The structure of the existing fan blade dynamic balancing machine is unstable. With the increase of the test volume, the error will continue to accumulate, thus affecting the test accuracy of the fan blade dynamic balance
