Bellows couplings are used to connect two shaft journals, for example the motor and gear of a drive unit. They have to be torsionally rigid, flexible, easy to assemble, economical, precise and very resilient. The bellow couplings with internal teeth from JAKOB Antriebstechnik meet these requirements.
The shaft-hub connection via a combination of clamping hub and toothing is particularly advantageous for gearboxes because it has a very low imbalance. It is also ideally suited for large, one-sided, but also for changing and jerky torques. Before the coupling is mounted on the motor shaft, the clamping hub is elastically expanded. The counter pressure required for this is generated by unscrewing the clamping screw against the so-called EASY pin. The coupling can then be easily plugged onto the shaft and tightened using the hexagon socket. When the motor and gearbox are connected via the lantern, the coupling hub centers itself and is mounted positively on the gear shaft. No further complicated tightening via mounting holes in the lantern is necessary.
A very precise connection to the drive shaft is created through the precisely manufactured internal toothing and a full inspection. As a result, the installation space can be reduced and no further connecting elements are required. An important point in terms of economy. Finally, an optional positive drive ensures reliability and safety in the event of a bellows rupture due to overload or excessive shaft misalignment. This feature is indispensable for gears for robotics, for example, to prevent a robot arm from falling.
Jakob Antriebstechnik offers the coupling with all common splined shaft gearing DIN 5480. Torques of up to 4000 Nm can be transmitted, the maximum shaft diameter is 102 mm.
Other nominal dimensions or custom-made products are possible on request from the manufacturer.
