Wave couplings from Ganter: precise and reliable

Shaft couplings from Ganter transmit rotational movements and torques from shaft to shaft. They also compensate for tolerances and mechanical errors that could otherwise lead to damage to drive or measurement configurations. Ganter offers a suitable coupling solution for almost every application.

Like all mechanical components, shafts are subject to manufacturing or assembly tolerances, which generally cannot be completely eliminated even with significant technical effort. If these mechanical deviations are not compensated, they can cause vibrations, noise, and stiffness, ultimately shortening the lifespan of the connected units.

The norm element specialists at Ganter have addressed these issues precisely. The result is shaft couplings that can be used both for torque and power transmission as well as for position and motion control. Thus, the right type of coupling is available for every application.

Despite the wide range of variations, the appropriate designs can be found quickly. An overview of the types of construction presents the key features of all shaft couplings at a glance, while the proven standard sheets document the details of each coupling standard. Further technical information on assembly and application, as well as details on speed, temperature, torsional stiffness, moment of inertia, etc., are compiled in a shaft coupling brochure – available in print or as a download.

The newly added shaft couplings made of aluminum or stainless steel can be attached either form-fit or force-fit. Multiple bore diameters, different stiffness and hardness grades of the coupling bodies, as well as an optional keyway, allow for very specific adaptation to the respective application. In general, all shaft couplings compensate for misalignments and offsets, absorb runout errors and axial movements, and damp vibrations and shocks to varying degrees.

At the application level, a distinction is made between position and motion control and torque and power transmission.

The rotational movement for position and motion control must be transmitted with high precision and positional accuracy. This requires a shaft coupling type that operates backlash-free in the direction of rotation and has high torsional stiffness. Typical application examples include: servo or stepper motors for linear axes, industrial robots, testing machines.

In contrast, torque and power transmission focus solely on force transfer. For this purpose, shaft couplings are needed that can withstand high torques and heavy loads and operate durably in rough environments. Typical application examples include: conveyor systems, pumps and gearboxes, packaging machines.
