Installation Instructions for Diaphragm Coupling

　Installation instructions for diaphragm coupling:

　　Before installing the diaphragm coupling, 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 coupling, and whether the inner holes are edged. Whether there are bruises on the edges, clean the shaft and half couplings 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.

　　2. In order to facilitate the installation, it is better 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, 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: 3-4 points of readings measured along the two inner sides of the flange of the half coupling are averaged, and the sum of the measured dimensions of the extension and the two diaphragm sets, both The error is controlled within the range of 0-0.4mm.

　　3. 找正：用百分表检测两半联轴节法兰盘端面和外圆跳动,当法兰盘外圆小于250mm时跳动值应不大于0.05mm;当法兰盘外圆大于250mm时,跳动值应不大于0.08,
