Benefits » ZAPEX gear couplings link machine shafts and compensate for shaft misalignment with weak restorative forces. » High transmissible torque combined with compactness and light weight are characteristic of ZAPEX couplings. » ZAPEX couplings require very little maintenance. Regular grease or oil changes at the prescribed intervals prolongs the service life of the coupling. Application » ZAPEX couplings are especially suited for operation in harsh operating conditions, such as drives in the iron smelting or cement industry. » ZAPEX couplings are suitable for reverse operation and horizontal mounting positions and, in the case of type ZWNV, for vertical mounting positions. Function » The torque is transmitted through the coupling teeth. The teeth are crowned, so angular displacement per tooth plane is possible. » Radial displacement can be compensated for via the space VA between the tooth planes. The internal teeth of the flanged sleeves are significantly wider than the external teeth of the hub parts, permitting a relatively high axial misalignment. » A small angular misalignment on the coupling teeth results in an advantageous distribution of the lubricant film and a very low wear rate. This favourable condition can be deliberately set by aligning the drive with the machine shafts with a slight radial misalignment.

Benefits » N-ARPEX couplings of the ARN-6/-8/-10 series are outstanding for their application-optimized construction. » API 610 &API 671 compliance on request. » A special catching device acts to secure the intermediate spacer in the event of plate breakage. » ATEX compliance on request. Application » N-ARPEX couplings of the ARN-6/-8/-10 series are used wherever reliable torque transmission is called for, even in cases of often unavoidable shaft misalignment. They are universally applicable over a temperature range of from -50°C (or even as low as -60°C on request) up to +280°C, are torsionally rigid, free of torsional backlash and enable quiet running at a constant angular velocity. They are wear- free and maintenance-free and, if correctly fitted, can be expected to have an unlimited service life. Plate-PackDesigns » The plate packs of the N-ARPEX ARN series are designed with hexagon, octagon and decagon plates, depending on the coupling size. The number of screw connections is indicated in the denomination of the ARN-6/-8/-10 series. Hexagon plates have 6 bolting points, octagon plates have 8 bolting points and decagon plates have 10 bolting points. The hexagon plates, octagon plates and decagon plates up to size 631 are designed as ring plates. Sizes 694 to 988 are designed as segmented plates.

Benefits » RUPEX couplings can hold loads whilst overloaded therefore especially suitable for drives for special safety and reliability requirements. » Torque shock loads and changing loads are no problem for robust, compact flexible RUPEX couplings. » Low maintenance. Only the elastomer elements, as wear parts, need be replaced with no need to move the coupled machines. » Suitable for reversing operation and horizontal and vertical fitting or fitting at any required angle. Application » RUPEX couplings are available as a catalogue standard in 26 sizes with a rated torque of between 200 Nm and 1,300,000 Nm. » 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 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 safety-relevant areas of application are cable railway drives, lifting gear for crane drives or escalator drives. quality products for mechanical & fluid power ® RUPEX pin & bush couplings www.jbj.co.uk Design andConfigurations » 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. Link to ~ full technical specification catalogue
