The first step is to check whether the prime mover and the working machine are concentric, whether there are wrapping paper and scratches on the surfaces of the two shafts, whether there are debris in the inner holes of the two half couplings of the plum coupling, and whether the inner holes are ridged before installation. Whether there are bruises on the edges, clean up the shaft and half coupling if any, and treat the bruises with a fine file.Then check whether the inner hole diameter and length of the two half couplings are consistent with the diameter and shaft elongation of the prime mover and working machine.In general selection, it is better to let the length of the prime mover and the working machine end half coupling be less than the shaft extension of 10-30mm.
In the second step, in order to facilitate the installation, it is best to put the two half couplings in the 120-150 incubator or oil tank for preheating, so that the inner hole size increases and it is easy to install.After installation, ensure that the shaft head cannot protrude from the end face of the half coupling, and it is better to be flush.Detect the distance between the two halves of the coupling: take the average of the readings of 3 to 4 points measured along the two inner sides of the flange of the half coupling, and the sum of the measured dimensions of the extension and the two diaphragm sets, two The error is controlled within the range of 0-0.4mm. 3. Alignment: Use a dial indicator to detect the runout of the flange end face and outer circle of the two halves of the coupling flange. When the outer circle of the flange is less than 250mm, the runout value should not be greater than 0.05mm; when the outer circle of the flange is greater than 250mm , The jitter value should not be greater than 0.08.
The third step is to install the bolts: insert the bolts from the outside of the small hole of the flange, pass through the outside of the large hole of the other flange, put on the buffer sleeve, elastic washer, twist the nut, and tighten the nut with a wrench.If the installation is unsuitable or it is removed and replaced without damaging the shaft and the half coupling, it is better to rotate freely after installation.
Finally, before starting the equipment, check whether the nut of the plum coupling is loose or falling off. If so, tighten the nut with a wrench in time.
