The JZMJ diaphragm coupling is mainly used in power plants, cement plants, blowers and other equipment. It is mainly composed of several groups of diaphragms (stainless steel sheets) that are alternately connected to the two halves of the coupling with bolts. Each group of diaphragms is composed of several pieces. The diaphragm is divided into a connecting rod type and a whole piece type of different shapes.The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate for the relative displacement of the two shafts connected. It is a high-performance flexible coupling with a strong metal element. It does not require lubrication and has a compact structure.

　　JMIJ type connecting intermediate shaft type diaphragm coupling:

　　1. Before installation, check whether the prime mover and working machine shafts are concentric, whether there are wrapping paper and scratches on the surfaces of the two shafts, whether there are sundries in the inner holes of the two half couplings of the coupling, and whether there is any edge of the inner hole. 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 let the length of the prime mover and the working machine end half coupling be less than the shaft extension of 10-30mm.

　　2. 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.

　　3. 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, 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.

　　2: Diaphragm coupling: The elastic element of the JZMJ diaphragm coupling is a diaphragm assembly composed of thin stainless steel diaphragms. The diaphragms usually have a waist shape, a polygonal ring shape, etc., which are on the same distribution circle. The precision bolts are respectively connected with the driving and driven flanges.The diaphragm assembly bears the misalignment of the driving and driven flanges in the form of three-dimensional deformation.
