Pay attention to these when installing the plum coupling

来源:日期:2019/12/16 10:27:20

  Before installation, first 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 edges of the inner holes are bumped. If there is any damage, the shaft and half coupling should be cleaned up, and the damage 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.

  In order to facilitate the installation, put the two half couplings in the 120-150 incubator or oil tank for preheating, so that the inner hole size is enlarged 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.
