Gear coupling, gear joint spindle

Gear couplings are designed with crowned teeth and are used where torque must be transmitted with shaft connections that can move freely in three dimensions (angular, radial and axial). FLOHR has its own range of gear couplings for standard industrial applications. The program is supplemented by high-performance couplings from MALMEDIE Antriebstechnik GmbH. FLOHR uses the outstanding quality of the MALMEDIE coupling both in its own systems and as a sales partner for MALMEDIE Switzerland and MALMEDIE Austria.

With more than 50 years of operating experience using gear couplings within drive technology, this then speaks for the high performance and quality of the coupling units. The gear couplings can compensate for angular, radial and axial deviations. With the standard toothed coupling, the misalignment capability is ±0.75° per coupling half, special versions can be supplied up to ±5°.

  • Gear couplings GLX

    Gear couplings GLX

    The gear coupling GLX is easy to mount / dismantle due to the two-piece housing. At the same time, the distance between the two gears planes is more, allowing more radial compensation.

  • Gear couplings LX

    Gear couplings LX

    The Gear-Coupling LX is compact due to the single-piece housing. Ideal for applications with space restrictions.

Quality and production of gear couplings

All gear coupling parts are manufactured according to strict internal quality procedures. Modern CNC manufacturing technology ensures the interchangeability of individual parts. All power-transmitting clutch parts are made of high-quality heat-treated steel. In special cases, it is possible to increase the performance of the gear coupling or reduce wear through the targeted selection of materials and appropriate hardening processes. Professional and experienced installation and alignment of the coupling is also crucial. We would be happy to support you with any questions on this topic.

Laser Alignment

Structure and characteristics

The coupling hubs with crowned external splines run in housings with straight internal splines. This allows the coupling hubs to to have a three dimensional movement in the housings and compensate for angular, radial and axial deviations of the shafts to be connected. For standard gear couplings, the misalignment capability is ±0.75° per coupling half, special designs can be supplied up to ±5°.

Wear indicator

The optical wear indicator ensures that the wear of the coupling can be checked. This enables simple and safe monitoring of the units during operation, which reliably protects against failure. A sudden shutdown is avoided and the maintenance intervals by the experienced MALMEDIE team are reduced to a minimum downtime.
