The Gummi VN line jaw semi-elastic coupling joins two shafts with an elastic element and a steel ring: the VN model combines a jaw hub and a ring-carrier hub. It is a power transmission solution for equipment that needs to absorb misalignment and damp vibration without losing torque capacity. MR Accesorios Industriales sells it in Buenos Aires, Argentina, as an official distributor of Gummi, an Argentine coupling manufacturer.

The VN line is a jaw semi-elastic coupling: a jaw hub, a ring-carrier hub and an elastic element housed between them, with a steel ring that contains the assembly. That combination allows transmitting torque while absorbing misalignment and damping vibration. The designation is read with the line letters and the size: VN 170, VN 200, VN 240, VN 300, VN 350, VN 400, VN 450 and VN 500 are examples of the series. The VNDD line is the variant with additional hubs on both sides.

This type of coupling is used in machines that need to join shafts with some misalignment and damp movement: centrifugal pumps, compressors, fans, conveyor belts, mixers, mills and transmission equipment in general. In Argentine industry it appears in food, chemical, petrochemical and water treatment plants and in pumping and compressed air installations, where the coupling must accompany the continuous operation of the drive motor and the driven machine.

To choose the model, take into account the maximum torque transmitted by the equipment and the service factor according to the type of load, the diameter of the shafts to be joined, the rotation speed and the permissible misalignment. Assembly requires aligning the hubs as precisely as possible, checking the condition of the elastic element and controlling the tightening of the fastening elements. Maintenance focuses on checking the wear of the elastic element and the condition of the steel ring.

To request a quote, send us the model or the coupling code, the diameter of both shafts, the power and the rpm of the motor and the driven machine. With that data we help you choose the correct size of the VN line. If the equipment already has a coupling mounted, the model shown on the coupling plate or in the drawing is enough to identify the variant. Each product page shows the maximum torque, maximum speed, outer diameter, total length and weight of each size.
