Detailed analysis of the operation steps of the dynamic balancing machine
Operating steps of the dynamic balancing machine: clean before operation, especially the cleaning of the rotor journal, rollers, universal joints and joints. When installing the rotor, be sure to avoid the impact between the rotor and the roller, and install the rotor. After finishing, add a little clean oil to the journal and rollers. It is strictly forbidden to drive without connecting the rotor and the universal joint.
Connect the universal coupling size with the joint. The processing of the joint should be prepared according to the specific conditions of the workpiece. The shape of the joint should be symmetrical, and the weight should be light when the strength permits. The inner and outer circles of each gear should be concentric. The matching accuracy with the workpiece is H6/h6, and the matching accuracy of the concave hole at the joint with the universal coupling is also H6/h6, and the concentricity must be ensured, and the end face must be vertical to avoid affecting the accuracy.
Adjust the distance between the two swing frames and tighten them to fit the distance between the bearings at both ends of the rotor. Refer to the ruler on the roller frame according to the journal size of the rotor, adjust the height of the roller frame, and tighten it. Connect the workpiece with the universal joint and tighten it firmly, and tighten the stroke adjustment set screw of the universal joint to avoid axial movement of the workpiece.
The choice of speed can be determined according to the weight of the workpiece, the initial unbalance amount and the drag power of the rotor. The rotor weight is below 160 kg, high speed can be used; above 160 kg, low speed can be used. If the initial imbalance of the rotor is too large and even affects the running of the rotor on the support bearing, static balance should be performed first, and then low-speed verification. Although some rotors are not heavy, they have large outer diameters or have fan blades that affect the drag At the time of dynamic power, low-speed correction is also required.
