Different from the standard drum gear coupling, it adopts a narrow tooth width design (the axial dimension is significantly reduced), which greatly optimizes the space occupation while ensuring the load-bearing capacity, and is especially suitable for working conditions where the axial installation space is limited. This coupling achieves excellent angular (≤1.5°) and radial (≤0.3mm) displacement compensation capacity through the spherical profile of the drum-shaped external teeth , effectively absorbing the shaft system deviation and vibration during equipment operation. The tooth surface has undergone hardening and grinding treatment, combined with a forced lubrication system (requiring regular oil injection), significantly enhancing wear resistance and transmission efficiency. It can withstand high torque, high speed (≤5000rpm), and impact load . It is typically applied in compact heavy industrial transmission systems such as metallurgical rolling mills, mining crushers, and heavy conveying equipment, ensuring stable power transmission while solving the problem of space constraints.
The axial dimension is significantly reduced,making it suitable for space-constrained working conditions(such as narrow layout in equipment compartments),maximizing the savings of installation space while ensuring load-bearing capacity.
The external gear adopts a spherical profile design,which forms an adaptive meshing with the internal gear ring,effectively eliminating stress concentration.






Precision in power transmission is the cornerstone of high-performance automation. When dealing with servo systems, CNC equipment, or 3D printing modules, the slightest rotational clearance can lead to significant positioning errors and accelerated component wear. The aluminum alloy double diaphragm coupling is engineered specifically to eliminate this backlash while compensating for critical alignment deviations. By leveraging the elastic deformation of stainless steel diaphragms, this component ensures a rigid yet flexible torque transfer that protects sensitive encoders and motors from axial and radial stress. For procurement managers and system engineers, selecting a reliable flexible coupling Factory means balancing torsional rigidity with lightweight construction.
