Features:
Single diaphragm encoder shaft coupling or spring shaft coupling without lubrication and routine maintenance; The coupling state can be detected without disassembly; In addition, during the operation of the equipment, strobe light can be used to check the diaphragm, high torsional stiffness, zero rotation; If the installation is accurate, the coupling will not be damaged for life, the life of infinite long; No wear parts, but used in all kinds of harsh working conditions; If the offset error is within the defined range, the coupling will have the same life as the equipment; Super torque safe operation design, peak torque is 2 times of rated torque.
It is worth noting that because of the strong rigidity of the diaphragm coupling, if the deviation between the two shafts is too large when the equipment is installed, the diaphragm coupling will produce a large axial stress on the thrust bearing on the shaft. Therefore, it is very important for the application of diaphragm coupling, especially in high speed occasions, to make the diaphragm group have certain guiding and positioning ability.
