The function and error of the adjusted plum blossom coupling

The plum blossom coupling is tightly combined with polyurethane plastic as the elastic element and the main body of the second half coupling, with the main body mainly made of imported formula alloy aluminum. The polyurethane plastic component in the middle of the plum blossom coupling is formulated with a unique formula, which has high wear resistance, good temperature resistance, strong toughness, and stable and durable quality compared to ordinary plastic parts. The plum blossom shaped body can be divided into 6 and 8 petals, with a keyway for fixation. The plum blossom coupling is a mechanical component mainly used to connect two rotating shafts in mechanical transmission, in order to transmit torque or rotation angle.
Under normal circumstances, the height of the half coupling claw is the same, but there is also a slight difference in the length of the claw. If we measure it based on the top of the short claw at this time, it will cause the fit gap of the long claw to be too small or even unable to assemble. Therefore, when the claw length is small, adjust the end gap based on the long claw. The added half coupling of the motor may cause the motor output shaft to protrude relatively, and during assembly, the half coupling of the reducer is limited by the motor output shaft, resulting in the coupling being unable to be assembled to the predetermined end without clearance. Couplings are mainly suitable for working situations with frequent starting, forward and reverse rotation, medium to high speed, medium torque, and high reliability requirements.
The size of the chamfer on the inner side of the coupling is also a key factor affecting the end clearance of the coupling. As the step position of the motor output shaft is generally chamfered, when matched with the chamfer of the half coupling, it can usually affect the end clearance of the coupling by 2-4mm. Therefore, during the assembly process. Firstly, measure the size of the step on the output shaft of the motor or the step on the input shaft of the reducer, in order to chamfer the half coupling accordingly. Only then can the gap between the half coupling end be adjusted to the appropriate position. The plum blossom coupling works stably and reliably, with good vibration reduction, buffering, and electrical insulation performance. Simple structure, small radial size, light weight, small Moment of inertia, suitable for medium and high speed occasions.
The plum blossom coupling has large axial, radial, and angular compensation capabilities, and high-strength polyurethane elastic components are wear-resistant and oil resistant, with large load-bearing capacity and long service life. The coupling does not require lubrication and requires minimal maintenance, allowing for continuous and long-term operation. The plum coupling has the advantages of small radial size and Moment of inertia, no clearance, good damping and buffering effects, and strong axial, radial and angular compensation capabilities. Although the plum blossom coupling tool has good misalignment compensation ability, misalignment of the coupling still generates additional forces and moments on the rotor and bearing system, and these additional forces often bring serious consequences.
