Screw clamp type diaphragm coupling

Structural features :

It is mainly composed of two half Couplings, a diaphragm group and clamping screws. The half coupling is generally made of aluminum alloy, carbon steel and other materials, with high strength and rigidity. The diaphragm is usually made of stainless steel sheet. Multiple groups of diaphragms are staggered and connected to the two half couplings by bolts. Each group of diaphragms is composed of several pieces stacked together. Its shape includes connecting rod type and whole piece type.

Performance characteristics

1. High torsional rigidity

2. Zero rotational clearance 

3. Good compensation performance 

4. High sensitivity , no lubrication and maintenance required , corrosion and high temperature resistance , long service life

Technical Parameters

1. Model specifications: Common models include DBJ series, DEG series, CPSW series, etc. Different models correspond to different parameters such as size, torque transmission capacity, etc.

2. Shaft hole size: The diameter of the shaft hole has a wide range, generally ranging from a few millimeters to tens of millimeters. It can be selected according to the specific shaft diameter requirements of the equipment. For example, the inner hole size of the DBJ06-36 model can be selected between 4-85mm.

3. Allowable speed: Usually has a higher allowable speed, generally between thousands of revolutions per minute to tens of thousands of revolutions per minute. The specific value depends on factors such as the coupling model, size, material and diaphragm performance. For example, the allowable speed of the DBM31 model can reach 42000r/min6.

4. Allowable torque: The torque range is wide, ranging from a few Nm to hundreds of Nm, which can meet the transmission requirements of different power equipment. For example, the nominal torque of the DBM31 model is 1-30N.m
