GSTS Aluminum alloy single step single diaphragm clamp type coupling
Products 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.
Diaphragm coupling is suitable for shafting transmission in high temperature, high speed and corrosive medium working conditions, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery , chemical machinery, mining machinery, metallurgical machinery, aviation (helicopter), naval high-speed power transmission system, steam turbine, piston power mechanical transmission system, crawler vehicles, and generator set high-speed, high-power mechanical transmission system, through dynamic balance Later applied to high-speed transmission shafting has become more common.
Compared with the gear coupling, the diaphragm coupling has no relative sliding, does not need lubrication, sealing, no noise, basically does not need maintenance, is easy to manufacture, and can partially replace the gear coupling. Diaphragm couplings have been widely used in industrialized countries in the world. In my country, machinery industry standards have been formulated and revised to new industry standards: JB/T 9147-1999 (replacing ZB/T J19022-90) Couplings relationship between torques.
