JMIJ diaphragm couplingThe JMIJ diaphragm coupling has a strong ability to compensate for the misalignment of the two axes. Compared with the gear coupling, the angular position...The main advantage of the diaphragm coupling is that the diaphragm (stainless steel sheet) is used as the elastic element, so that it has the characteristics of stainless steel alkali resistance, acid resistance, and is especially suitable for shafting transmission in high temperature, high speed and corrosive medium conditions. .
The gap between the bolt fitting section of the diaphragm coupling and the flange hole fitting section is generally based on the bolt diameter of 0.20mm ~ 0.30mm. This fitting section plays a key role in transmitting torque. If the gap exceeds the standard, replace it.
The diaphragm coupling alignment tool includes a guide seat with a V-shaped groove at the bottom, a groove opening to one side and the top surface in the middle of the upper seat body, and a V-shaped groove at the bottom radially Intersecting and penetrating observation slots; measuring plate, L-shaped structure, thickness and guide seat
Diaphragm couplings rely on metal diaphragms to transmit torque and absorb deformation caused by misalignment. There is no relative movement between parts, no friction/wear, and no lubrication is required, which is in line with the development direction of oil-free process equipment.
The diaphragm coupling is composed of several groups of diaphragms that are interwoven and connected with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rod type and whole piece type with different shapes.
The JMI diaphragm coupling belongs to the JM series of diaphragm couplings that can compensate for the axial and radial directions caused by manufacturing errors, installation errors, load-bearing deformations, and temperature rise effects between the driving machine and the driven machine. And angular offset. The JMI diaphragm coupling is a flexible coupling with a metal elastic element. It relies on a metal diaphragm to connect the main and driven machines to transmit torque. It has the advantages of elastic vibration damping, no noise, and no need for lubrication.
The JMIJ diaphragm coupling has a strong ability to compensate for the misalignment of the two axes. Compared with the gear coupling, the angular displacement can be doubled, the reaction force is small during the radial displacement, the flexibility is large, and some axial and radial directions are allowed. And angular displacement. The JMIJ diaphragm coupling is different from the ordinary diaphragm coupling. It is not only connected with an intermediate shaft to extend the transmission distance, but also equipped with two diaphragms to increase the amount of flexibility compensation, so it is also called a double diaphragm coupling.
The JMⅡ diaphragm coupling belongs to the JM series of diaphragm couplings. It is composed of several groups of diaphragms (stainless steel thin plate) that are alternately connected with two halves of the coupling with bolts. Each group of diaphragms is made up of several pieces. , Diaphragm is divided into connecting rod type and whole piece type of different shapes.
