www.jbj.co.uk/couplings.html #DriveLineHarmony Introduction ® SITEX Gear Couplings 1 Description ® SITEX couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The hubs are made of steel and the teeth, which are both profiled and section crowned, are milled. The sleeve is manufactured from stabilized 6.6 super-polyamide resin. Features ® SITEX couplings are members of the elastic coupling family range. Sitex couplings are well suited for applications with axial, radial, and angular displacement of the connected shafts. The double cardanic action eliminates the imposition of loads on the shafts which results from radial and axial misalignment. The torsional rigidity of the sleeve prevents angular speed variation.The combination of steel hubs with Polyamide sleeve makes the coupling maintenance and lubrication free. The particular toothed profile prevents contact of tooth edges with the sleeve, ensuring long life of the coupling. Performance Mounting can be in both the horizontal and vertical planes. Installation is simple and quick, which lowers installation costs. The coupling is suitable for operating in temperatures ranging from - 25 °C to + 90 °C. For short intervals, temperatures of + 125 °C can be tolerated. Components of the coupling are resistant to all types of lubricants and hydraulic fluids. ATEX Directive 2014/34/EU It is possible to ask for specific certification for use in hazardous area according to ATEX Directive 2014/34/EU. SITEX® couplings are available with specific mounting/operating instruction manual and conformity. For information, please contact our technical office. GDM...F.. AD GDM..

Selection According toTorque ® The maximum starting torque of the driver or driven machine must not exceed the maximum torque capacity of SITEX . With uniform loading and well aligned ® ® shafts, SITEX can be operated at all torques up to the maximum. In case of irregular torque, consider that the SITEX coupling can bear peak loads up to 3 times the nominal torque indicated. The values shown in the table for radial and angular misalignment, must be adjusted in cases where they are simultaneously acting on the coupling. The sum of the admissible value (A) and the respective values shown in the table must be lower or equal to 1. Mounting Instructions » Attach the hubs to the shafts, taking care to align the inner surfaces with the corresponding shaft ends. » Insert the sleeve on the two hubs adjusting the distance (dimension “b”) of the same ones trying at the same time to align the two shafts as much as possible. » Tighten into position the two elements to be coupled. » Before rotating the coupling, be sure the sleeve is free to move axially. 3 T Coupling nominal torque Nm KN T Coupling maximum torque Nm Kmax W Weight kg J Coupling moment of inertia kgm2 ΔK Maximum axial misalignment mm a ΔK Maximum radial misalignment mm r ΔK Maximum angular misalignment ° w n Maximum rpm min-1 max

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.
