Rupex pin and bush couplings

RUPEX couplings are available as a catalogue standard in 26 sizes with a rated torque of between 200 Nm and 1,300,000 Nm. The coupling is suitable for use at ambient temperatures of between -30°C and +80°C. By using alternative elastomer elements, the permissible ambient temperature range can be extended to between -50°C and +100°C. Frequently, the coupling is used to connect the gear shaft to the driven machine. In the case of drives without gear units, the coupling is particularly suitable for operation in harsh conditions or heavy-duty drives with electric motor drive. Ventilator drives with high ventilator mass and drives in the cement industry are typical applications. Examples of particularly safety-relevant areas of application are cable railway drives, lifting gear for crane drives or escalator drives. A RUPEX coupling comprises two hub sections which are mounted on the machine shafts. The hub parts are connected positively by steel pins and elastomer elements. The coupling can be fitted with add-on parts such as brake disks or brake drums. Up to size 360, the pins and buffers are fitted on one side. From size 400 up, the pins and buffers are fitted in the hubs on alternate sides.
