Jiangsu JMⅡJ type diaphragm coupling with intermediate shaft

JMⅡJ type with intermediate shaft typeDiaphragm couplingCompared with the gear coupling, there is no relative sliding, no lubrication, sealing, no noise, basically no maintenance, more convenient to manufacture, and can partially replace the gear coupling.

JMⅡJ intermediate shaft type diaphragm coupling is widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textiles High-speed power transmission systems of machinery, chemical machinery, mining machinery, metallurgical machinery, aviation (helicopters), and naval vessels are commonly used in high-speed transmission shaft systems after being dynamically balanced.

JMⅡJ intermediate shaft type diaphragm coupling is a high-performance flexible coupling popularized and applied in my country, and it has been widely used in developed industries.In practical applications, the intermediate shaft type is generally used to improve the performance of two-axis offset compensation.

The JMⅡJ intermediate shaft type diaphragm coupling is composed of several groups of diaphragms (stainless steel thin plate) which are alternately connected to the two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragm is divided into Link type and different shapes of the whole piece type.

JMⅡJ Type Intermediate Shaft Type Diaphragm Coupling Installation Instructions 

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. 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 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. 

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。
