The Gummi VNDD line jaw semi-elastic coupling transmits power between shafts and absorbs misalignment and vibration. It has an elastic element with a steel ring and additional hubs on both sides. It is used in pumps, gearboxes, fans and other machines in Argentine industry. MR Accesorios Industriales, Buenos Aires, Argentina, quotes it for you on WhatsApp.
The VNDD line is a jaw semi-elastic coupling: motion passes from the hub on one shaft to the elastic element and from there to the hub on the other shaft. The elastic element works with a steel ring that supports it. The designation is read with the line letters and the size: VNDD 170, VNDD 200, VNDD 240 and the rest. Each product page shows the maximum torque, maximum speed, outer diameter, overall length and shaft diameter range.
This type of coupling is used to connect the shaft of a motor or gearbox with that of a driven machine. It appears in centrifugal pumps, fans, blowers, conveyor belts, mixers and process equipment. In Argentine industry it is common in food, chemical, paper and water treatment plants. The elastic element dampens startup and torque, and tolerates small misalignments between shafts.
To choose the model, start from the torque the machine transmits and apply a service factor according to the type of load and the working hours. Then look at the diameter of each shaft: it must fit within the range the hub accepts. Rotation speed also counts: each size has its maximum speed. During assembly, align the shafts with a straightedge or dial indicator before tightening, and check the elastic element from time to time to see if it has worn.
To request a quote, send us the model or part number, for example VNDD 170 or VNDD 300, 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 right size. If you have the part number from another brand or an unidentified part, write to us and we will look at it together.
MR Accesorios Industriales sells the VNDD line as official distributor of Gummi, an Argentine coupling manufacturer. Write to us on WhatsApp with the part number or model you need and we will quote it shortly.
