www.jbj.co.uk/couplings.html #DriveLineHarmony Introduction ® SITEX ST Gear Couplings 1 Description ® SITEX ST couplings are fully manufactured in high quality steel. They are made of 1 or 2 geared hubs which are coupled with one sleeve through which the torque is transmitted. The special OPTIGEAR profile allows very high torque transmission and the compensation of axial, angular and radial misalignment (only in the version with 2 hubs). The maximum recommended working temperature is -10°C to + 80°C. For special applications special materials should be used. Please contact jbj Techniques Limited technical office, telephone: +44 (0)1737 767493 or email info@jbj.co.uk for information. Features With the special design of the OPTIGEAR crown, the contact surface area under misalignment is larger than conventional crown. This results in the surface stresses being reduced resulting in a longer coupling life. Therefore, backlash is reduced to a minimum, reducing impact load in reverse application, and allowing optimum torque transmission and low vibration. All this results in an improved machine design. OPTIGEAR Profile ® SITEX ST couplings are machined with the unique OPTIGEAR profile, ensuring backlash is reduced to a minimum reducing impact load in reverse applications and allowing optimum torque transmission and low vibration. The result is a compact coupling keeping the application machine design optimized in size and work capacity. Interchangeability The range GST CF “A-B-C” conforms to AGMA specification in flange dimensions, type and positions of the screws. They are therefore interchangeable with ® any other AGMA coupling half. The most compact solution due to the exceptional torque transmission capability, SITEX ST couplings are the most compact solution in weight and dimensions for a safe torque transmission.

www.jbj.co.uk/couplings.html #DriveLineHarmony Installation and Maintenance Good alignment of the shafts help to reduce reaction forces on shafts and bearing and is important for the coupling life. In case the hubs are machined by the user in order to adapt them to the machine, it is user responsibility: » to control all parameters regarding balancing, bore concentricity and any other parameter which may affect coupling life and a safe transmission, are respected. » to verify the hub length and corresponding keyway seat are compatible with the necessary toque transmission considering the peak loads. Maximum bore diameters allowed in hubs as described in dimensional tables. » to verify the hub material is adequate for the clamping system. During compensation of misalignments, axial forces are generated. These forces must be considered when sizing machine bearing. For a calculation, please consult our technical office. It is also recommended that hubs are axially secured in order to avoid axial forces on the seals which may cause lubricant leakage and, therefore, shorter coupling life. It is recommended to secure the set screw with Loctite, use an end plate, or interference fit. Warning Gear couplings are rotating parts and potentially dangerous. It is recommended to protect the rotating parts and comply with existing safety regulations in order to keep personnel and equipment safe. Mounting SITEX® ST couplings must be stored in a non-corrosive environment prior to installation. In case of environments with high humidity it is the user’s, responsibility to protect the couplings, or to ask for a special surface treatment. Prior to starting the mounting operation, it is recommended to: » verify there are no missing or damaged components » have the necessary mounting instructions and tools required for mounting and shaft alignment. » make sure the machine is shut down and there is no risk of accidental start up » be careful in handling the coupling components. Particular care should be taken with the geared crown. 1) Check all components to be assembled are clean. 2) Position one snap ring and one seal on every shaft. 3) Position the hubs on the respective shafts. If necessary in order to facilitate the mounting operation, it is possible to heat the hubs (max. 120 °C). In such cases avoid contact between hub and seal until room temperature is reached. For a safe mounting hub must be positioned flush with the shaft. Mount the set screws and tighten properly. In order to avoid accidental screws loosening due to vibration, use some Loctite glue. 4) Mount the sleeve on the longer shaft. 5) Position the units to be connected respecting the dimension“E” between the shafts. 6) Align the 2 shafts being careful that the catalogue values are respected. It is possible to use the SIT LINE-LASER® to facilitate the operation. 7) Couplings are delivered without lubricant. Lightly grease the geared parts of hubs and sleeve. Lightly lubricate the seal and position them on the respective hubs. 8) Position the sleeve on the hubs. Insert the seals and the snap rings on the proper groove. 9) Remove the grease nipple and properly fill the chamber with grease. For the CF type, repeat the operation on the second half coupling. Position the grease nipple and tighten properly. Inspect and maintain. It is recommended to make a regular inspection which may detect abnormal noise, vibration, or leakage. Every 5.000 hours, or once a year, remove grease nipples, position the coupling with one nipple at 45° with respect to the rotation axis, force grease from the bottom hole until clean grease flows. Reinsert the nipples and tighten properly. Every 10.000 hours or every 2 years, remove snap rings and seals, clean and inspect seals and geared parts, verify alignments and mount the coupling. Low viscosity oil may be used to clean the coupling from used grease. Installation and Maintenance ® SITEX ST Gear Couplings 8

An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level. With a vast array of components to select from, jbj are well placed to provide all required components to support the required cooling system.
