Diaphragm coupling is divided into: half coupling, intermediate shaft, diaphragm, standard parts and other parts. The diaphragm is made of high quality spring stainless steel, with high tensile strength, fast deformation recovery, good elasticity and toughness; The semi-coupling is made of high quality alloy steel, which has good comprehensive mechanical properties after quenching and tempering. The tensile strength is more than 810MPa, and the yield strength is more than 785MPa.

The diaphragm coupling can COMPENSATE THE ERROR between two concentric shafts. For the axial, angular and radial compensation, please refer to our sample or log on WWW.NLY.CN.

The advantages of diaphragm coupling: high speed (high speed can be to 10-30,000rpm), simple structure, light weight, buffering, maintenance-free, easy installation. Suitable for test bench, fan, water pump, oil pump, crusher, machine tool, metallurgy, mining, cement, aluminum, rolling and other occasions.

Key points of diaphragm coupling installation:

1. Strictly follow the instructions to find the required range, the better the accuracy, the higher the diaphragm service life.

2. The bolt must be passed through the small hole of one flange, then through the diaphragm, and then through the large hole of the other flange, and as required

Tighten the nut by tightening torque.

3. After 48 hours of continuous operation, check the bolts one by one according to the tightening torque. If the site is not allowed to shut down, can be in

Add thread glue to the thread when tightening it for the first time to prevent the nut from loosening.

4. Check the operation of the diaphragm regularly. When the noise increases or diaphragm fragments fly out, please stop the machine for maintenance in time.

The advantages of diaphragm coupling: high speed (high speed can be to 10-30,000rpm), simple structure, light weight, buffering, maintenance-free, easy installation. Suitable for test bench, water pump, oil pump, crusher, machine tool, metallurgy, mining, cement, aluminum, rolling and other occasions.

Key points of transportation and storage:

1. The diaphragm is strictly forbidden to bend and squeeze; If necessary, it can be hung vertically to prevent deformation.

2. Diaphragm coupling shall not be placed vertically;

3. If the machine is not used for a long time, pay attention to rust prevention.
