Product Description

Double-diaphragm and small axial opposite wheel type coupling is the patent product developed by our factory, the patent NO.ZL.99 2 46247.9.

With compact structure, the adjustment capacity anti-impact and vibration-absorbing etc properties will be higher by 35%-40% than thoes of single diaphragm opposite wheel type.

Under unexpected diaphragm breakage conditions, the plum blossom shape flange can still transfer the torque, the safety property is good.

Mounting and dismounting are conveninet, it does not need to remove the motor or speed-reducer.


With high strength and large bearing capacity. It can transfer torque several millions, and can also adapt to super large equipments, such as steel rolling, iron smelting, cement, etc.

With small mass, high precision and reasonable design. It adapts to hitech equipment with speed over 10000RPM, such as oceangoing, aviation, spaceflinght, petrochemical, etc.

Thebolt connection is a reaming bore close fit connection without clearance, and stamping match marks. The dynamic balancing precision of the coupling is high; there are no empty spots when the coupling rotates clockwise or anticlockwise. The product can be used for singnal transmission and digital control equipment.

Good mechanical property, small ‘s heavy machinery industry,whichis one of the largest coupling manufacturers in China and own many patents in coupling.

Importantly, we arethe Sinopec member unit has passed ISO9001: 2000 international quality system certification. It is mainly engaged in research and development, design, production and sales of power transmission system components. The universal coupling manufacturing technology has filled the gap in this technology in China.

Engaged in the production of various national standard, non-standard couplings, and the manufacturing and processing of auxiliary equipment in various mining, metallurgy, coal, chemical and other industries.
