Jiangsu JMIJ type intermediate shaft type diaphragm coupling

JMIJ type with intermediate shaft typeDiaphragm couplingBefore installation, check whether the prime mover and the working machine are concentric, whether there are wrapping paper and bruises 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 there are bruises on the edges of the inner holes. , If necessary, clean up the shafts and half couplings, 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 make the length of the prime mover and the working machine end half-coupling less than the shaft extension of 10-30mm.In order to facilitate the installation of the JMIJ intermediate shaft diaphragm coupling, the two half couplings are placed in the 120-150 incubator or oil tank for preheating, so that the inner hole size is enlarged and it is easy to install.

1. Before installation, check whether the two shafts of 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 there are any edges of the inner holes. 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, the two half couplings are placed 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, the shaft head should not protrude from the end face of the half coupling, 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 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; when the outer circle of the flange is greater than 250mm , The runout value should not be greater than 0.08. High-speed, high-torque shafting transmission.As well as the shafting transmission with little change in the load of various mechanical devices, it has strong versatility.
