1. Before installation, first check whether the prime mover and the working machine are concentric, whether there are wrapping paper and bumps 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 edges of the inner holes are If there are bruises, the shaft and half coupling should be cleaned up, and the bruises should be treated 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 make the length of the prime mover and the working machine end half-coupling less than its shaft elongation 10-30mm.
2. In order to facilitate the installation, it is best to preheat the two half-couplings 120-150 in the incubator or the oil tank, 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 3-4 points measured along the inner side of the flange of the half of the coupling, and the sum of the measured dimensions of the extension and the two diaphragm sets, the error between the two Control within the range of 0-0.4mm.
3. Alignment: Use a dial indicator to detect the runout of the flange end and outer circle of the two halves of the coupling. When the outer circle of the flange is less than 250mm, the runout value should not be greater than 0.05mm, and when the outer circle of the flange is less than 250mm , The jitter value should not be greater than 0.08.
4. 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 on the screw, 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.
5. Instructions for the operator: 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.
