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.
