Shanghai stainless steel diaphragm

The stainless steel diaphragm has 7 structural types, the smaller coupling transmission torque range starts from 10Nm, andCoupling传递转矩范围可达8100000Nm，由于膜片具有6角、8角或多或10角的造型、所以转矩传递十分均匀，其适用环境温度可从–20℃至少+280℃、采用特殊材质适用。

Stainless steel diaphragm structure medium

The ambient temperature can be from -196℃ to at least +350℃, stable, and can be used in areas with explosion hazard.

High-speed series (8 corneal lenses)

Torque transmission range: 5000Nm to 56000Nm

These structural types each have some different structural characteristics and performance to meet the needs of a wide range of applications.

Rigid coupling without torsion backlash;

Compensate the radial, axial and angular alignment deviation of the shaft by applying two sets of diaphragms;

Made of elastic CrNi-stainless steel, no maintenance required;

Diaphragm installation, easy to change;

The components are manufactured according to the principle of modularity and are widely used.

Advantages of stainless steel diaphragm

No need for lubrication and routine maintenance;

The state of the coupling can be detected without disassembly; in addition, the diaphragm can be checked by the strobe light during the operation of the equipment

High torsional rigidity, zero rotation;

If the installation is accurate, the coupling will not be damaged for life, and the service life will be long;

No wearing parts, but can be used in various harsh working conditions;

If the offset error is within the limited range, the coupling will have the same long life as the equipment;

Super torque operation design, the peak torque is twice the rated torque.

It is worth noting that due to 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 generate a great axial stress on the thrust bearing on the shaft.Therefore, the guiding and positioning capabilities of the diaphragm pack are critical to the application of diaphragm couplings, especially in high-speed applications.

Application range

As high-speed couplings and low-speed high-torque couplings, it can be widely used in general machinery and equipment, such as papermaking machinery and equipment, pump rotation systems, ventilation equipment, material processing, etc. Smaller couplings can be used in control systems.

Compressors, generators, pumps, dynamometers, drilling equipment, boiler feed pumps, turbine drives
