Diaphragm coupling

DiaphragmCouplingThe elastic element is a diaphragm assembly composed of thin stainless steel diaphragms. The diaphragm usually has a waist shape, a polygonal ring shape, etc., and the dense bolts on the same distribution circle are connected with the driving and driven flanges.

  DiaphragmCouplingThe elastic element is a diaphragm assembly composed of thin stainless steel diaphragms. The diaphragms usually have a waist shape, a polygonal ring shape, etc., and dense bolts on the same distribution circle are connected to the driving and driven flanges.The diaphragm assembly bears the misalignment of the driving and driven flanges in the form of three-dimensional deformation.  
Diaphragm couplingAlso called elastic laminated coupling, or laminated flexible coupling, one of the new couplings developed in recent years. This product is a new product successfully developed by our factory through continuous absorption of foreign advanced technology. The metal The diaphragm coupling can compensate various misalignment errors (radial error, axial error, angular displacement error, error caused by temperature rise) of the connected two shaft systems, JMI type basic diaphragm with counterbore The coupling mainly relies on the elastic metal diaphragm in the middle of the coupling to transmit the torque between the two shafts. It has the advantages of damping and absorbing vibration, no wear, and no maintenance. It is today's alternative to gear couplings and general couplings The ideal product of our factory is (JB/T 9147-1999).
Main features of JMI diaphragm coupling
1. The ability to compensate the misalignment of the two axes is strong. Compared with the gear coupling, the angular displacement can be doubled, the reaction force is small during radial displacement, the flexibility is large, and certain axial, radial and angular directions are allowed. Displacement.
2. It has obvious shock absorption, no noise and no wear.
3. The transmission efficiency is high, up to 99.86%.Especially suitable for medium, high speed and high power transmission.
4. It is suitable for working in high temperature (-80+300) and harsh environment, and can move under shock and vibration conditions.
5. Simple structure, light weight, small size, convenient assembly and disassembly.The machine can be assembled and disassembled without moving the machine (refer to the type with intermediate shaft) without lubrication.
6. It can accurately transmit the speed without slip, and can be used for the transmission of dense machinery. JMI diaphragm couplings are widely used in metallurgy, mining, petroleum, chemical, electric power, shipbuilding, lifting and transportation, textiles, light industry, agricultural machinery, printing machinery and water pumps, fans, machine tools and other industries to transmit power in mechanical equipment.
