We – EPG Team the biggest couplings and gears factory in China with 5 distinct branches. For much more details: Cellular/whatsapp/telegram/Kakao us at: 0086-13083988828 /
Universal joints, or common couplings, perform in a equivalent manner to provide a total assortment of motion. They allow the shaft to rotate and bend even though nonetheless offering torque to the wheels. The central hub of the universal joint is the place the shaft is joined to the third element. This permits for much more bending than in a versatile shaft coupling. gear kind flexible coupling The new items consist of a sequence of high-tech and large good quality chains and sprockets and gears, this sort of as chains and gearboxes for agricultural machineries, metallurgical chains, escalator phase-chains, high-pace tooth chains, timing chains, self-lubrication chains, among which have variety large velocity tooth chain for auto department dynamic box and aerial chains fill in the blanks of chain in China.

Standard circumstance of diaphragm coupling used to variable frequency pace management tools
JMB kind coupling is applied to Daqing Oilfield Thermal Electrical power Plant
According to the demands of Daqing Electric Power Corporation, Daqing Oilfield Thermal Power Plant need to dynamically change the electricity era according to the load of the power grid and market place desire, and have out the transformation of the frequency converter and the suction enthusiast. The motor was originally a 1600KW, 730RPM non-frequency variable velocity motor matched by Shenyang Motor Factory. The velocity management mode following shifting the frequency is handbook control. Press the button speed to enhance 10RPM or fall 10RPM. The coupling is nonetheless the first elastic decoupling coupling, and the elastic de-coupling coupling right after frequency conversion is usually ruined, which directly influences the standard power technology.
It is identified by means of evaluation that in the procedure of frequency conversion speed regulation, the pin of the coupling can not bear the inertia of the pace regulation process (the diameter of the admirer impeller is three.three meters) and is cut off, which has fantastic injury to the motor and the admirer.
Later, they switched to the JMB460 double-diaphragm wheel-variety coupling of our manufacturing unit (patent variety: ZL.99246247.nine). Soon after one hour of destructive experiment and a lot more than a single 12 months of operation test, the equipment is running quite effectively, and there is no Change the diaphragm. 12 models have been rebuilt and the operation is in great problem.
