Articulated gear couplings

Articulated gear couplings assume a double function as a connecting element between the drive unit and lifting device, for example in a crane and hoist device. In addition to transmitting the torque, the coupling supports the forces acting radially on the drum. The articulated coupling is torsionally rigid, yet flexible in all directions, which offers significant advantages in comparison with a rigid coupling.

The articulated gear couplings consists of the coupling hub with milled, curved toothing, which meshes with the coupling housing with beveled internal spur toothing. The coupling hub is fixed to the gear shaft. A cylindrical shaft seat with a keyway connection is typical. Other connections, such as a shrink seat or splined shaft, are also optionally available. The transmitted torque as well as the maximum permissible shear load can also be increased with additionally hardened toothing.

Articulated gear couplings are primarily used in the area of hoisting and conveyor technology in crane hoists and hoisting drum drive systems.

Gear couplings

Gear spindle couplings

Gear spindle couplings are primarily used where large torques need to be transmitted in conjunction with the smallest external diameters and a high misalignment compensation capability is simultaneously required. This is the case with hot and cold rolling mills, continuous casting systems, straightening presses, and rotary furnaces in particular.
