Common joints, or universal couplings, work in a equivalent fashion to supply a full selection of movement. They let the shaft to rotate and bend while nevertheless offering torque to the wheels. The central hub of the common joint is where the shaft is joined to the 3rd aspect. This permits for much more bending than in a flexible shaft coupling. China bowex coupling Our items are utilized in numerous fields.

Typical situation of diaphragm coupling used to variable frequency velocity management tools
JMB sort coupling is applied to Daqing Oilfield Thermal Power Plant
In accordance to the demands of Daqing Electric Power Corporation, Daqing Oilfield Thermal Electricity Plant must dynamically adjust the electricity technology according to the load of the power grid and market desire, and have out the transformation of the frequency converter and the suction admirer. The motor was at first a 1600KW, 730RPM non-frequency variable pace motor matched by Shenyang Motor Manufacturing unit. The velocity management mode soon after changing the frequency is manual management. Press the button speed to enhance 10RPM or drop 10RPM. The coupling is still the original elastic decoupling coupling, and the elastic de-coupling coupling following frequency conversion is frequently broken, which straight influences the normal energy generation.
It is identified via investigation that in the procedure of frequency conversion velocity regulation, the pin of the coupling can not bear the inertia of the pace regulation approach (the diameter of the supporter impeller is three.3 meters) and is cut off, which has wonderful hurt to the motor and the fan.
Afterwards, they switched to the JMB460 double-diaphragm wheel-type coupling of our manufacturing facility (patent amount: ZL.99246247.nine). Following one hour of destructive experiment and far more than one calendar year of procedure check, the products is operating quite properly, and there is no Substitute the diaphragm. twelve units have been rebuilt and the operation is in very good condition.
