www.jbj.co.uk/couplings.html #DriveLineHarmony Series “P” - “E” - “H” (DIN 808) SIT Universal Joints 1 With Plain or Needle Roller Bearings P series joints are precision products made by 4 forks and solid pins machined from one piece, to have an extremely compact central block. Types E are with sliding bushes while type H has needle roller bearings. It’s produced in one only version: » P series according with DIN 808. Joints with plain bearings are available in 2 versions: » E series according with DIN 808. » EB series according with DIN 808/7551. Joints with roller bearings are available in 2 versions: » H series according with DIN 808. » HB series according with DIN 808/7551. Every model is made by 2 hubs with forks and a central block. Between pins and bores there are: » P series: 4 bearings with solid pins. » E series: with sliding bushes. » H series: with needle roller bearings. In the central blocks of P and E series there are the holes for lubrication. For the H series (for high speed applications) no lubrication is needed, because the roller bearing are maintenance free. P series joints is designed for high precision and lifetime applications. E series joint with sliding bushes are used for low-medium speed and when some shock load can occur. For high speed and medium torque, we suggest the type H with roller bearings. The maximum working angle is 45° for single joints, 90° for double joints. The maximum speed is 1000 rpm for P and E series, 4000 rpm for H series. Every execution can be supplied with extendable shaft. Selecting criteria Matching one single joint with two shafts (of which the driving one is rotating at a constant speed), it forms an angle which causes a periodic variation of the driven shaft, exactly four fluctuations per revolution. The difference between the maximum and the minimum speed of the driven shaft depends on the angle formed by the two shafts. The difference grows when increasing of the angle α. To have a homokinetic transmission, you have to fit either two opposite single joints (paying attention that the two central yokes lie on the same plain and the angles are equal) or a double joint. The irregularity caused by the former articulation is cancelled by the latter. The overall length resulting from the coupling of the two single joints is even more reduced using a double joint. In other words, the double joint is to be considered the shortest homokinetic transmission. For low speed applications (max 1.000 rpm) joint with plain bearings (rubbing bearings) are suggested: types E/EB. They are able to support shock loads, drive reserves, irregular running and relatively high torques. The working angles must be reduced in operation between 500 and 1.000 rpm. For high rotation speeds, relatively low torques or wide angles, joints with needle roller bearings (type V - H) are preferred. They can reach 5.000 rpm always relating to the angle. How to read diagrams The joint capacity to transmit a regular torque at a constant load with no shocks for a more or less long period, mainly depends on the number of revolutions per minute and the inclination angle α of the two axes. The following diagrams are based upon the criteria below. Each curve corresponds to the joint size (outside diameter D) and represents the torque that the joint can transmit depending upon speed and working angle α. The diagrams can be directly read if angle α is 10°; for wider angles, torques are reduced, therefore the values are to be corrected using correction factors (F) relating to the angle shown in the table. Note: Values shown in the diagrams are indicative only. Each application has its own particular motion characteristics, eg. shock loads, motion reversals, connected masses, type of starting, presence of elastic joints, stops and starts, etc. Call jbj Techniques Limited technical office, telephone: +44 (0)1737 767493 or email: info@jbj.co.uk for assistance.

www.jbj.co.uk/couplings.html #DriveLineHarmony 4 Installation SIT Universal Joints Fig. 1 Fig. 2 To obtain a uniform rotary motion, always use two opposite single joints or one double joint. The pillow blocks must be positioned as close as possible to the joints (see figure 1 and 2). Fig. 3 correct wrong Fig. 4 When using two opposite single joints, respect the alignment of the inside yokes. In extensible transmissions also pay attention to the arrows stamped tally (see figure 3 CORRECT, figure 4 WRONG). Fig. 5 correct wrong Fig. 6 The joints angle α must be equal (see figure 5). The shafts can be moved one from the other either parallel or symmetrically. Pin holes must not be executed over the yokes to avoid damage (see figure 6).

Brass Couplings Hubs made in brass and spider in rubber. Suitable for low power. ® TRASCO Spider Couplings The flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class. It has a very compact design and allows safe power transmission by absorbing peak loads and torsional vibrations. The elastomeric design of the polyurethane gear ring compensates for angular, radial and axial misalignments. ® METALDRIVE Disc Couplings Made of steel and are used in all applications where high reliability, precision, and no maintenance are required. ® All the components of the METALDRIVE couplings are completely machined (spacer excluded) and balanced in class DIN ISO 1940-1 Q 6,3. ® TRASCO ES Spider Couplings » “Zero-backlash” motion transmission. » Dampening (up to 80%) of vibrations from motor shaft. » Low heat and electrical conductivity. » Easy and fast installation. » Perfect balance (A & AP type). » Low moment of inertia (due to compact design and types of materials used). ® SITEX Gear Couplings Two steel gear hubs, connected with one internally toothed sleeve of stabilized 6.6 super polyamide resin. ® ® SITEX NYLEX couplings are made of 100% Polyamide. Designed for light applications, low cost and available with finished bore keyway and thread for set screw. ® The SITEX FL couplings are designed to optimize the connections between diesel engines and driven equipment such as hydraulic pumps. * Summary Mechanical Power Transmission Couplings
www.jbj.co.uk/couplings.html #DriveLineHarmony Bolt Couplings The bolt coupling is a rigid coupling. It is made of two halves, which are cast iron grade GG25 connected by means of bolts. It is maintenance and lubrication free. Additionally, its construction prevents fretting corrosion and allows for easy mounting and dismounting. The bolt coupling is designed to connect horizontal shafts with similar diameters. For different applications please contact our technical department. Universal Joints High precision universal joint, manufactured according to DIN 808/7551. Every model type is made of 2 hubs with forks and a central block. Between pins and bores there are: » P series: 4 bearings with solid pins. » E series: with sliding bushes. » H series: with needle roller bearings. ® SITEX ST Couplings 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 a + 80 °C. ® SAFEMAX Torque Limiters Prevents damage to machinery happening through instant disengagement of the motor side from the driven side in case of torque overload, thus eliminating the risk of expensive downtime. In addition, these torque limiters, being torsionally rigid and backlash free, allow a rapid and accurate resumption of machine operations once the cause of the overload has been eliminated. ® SERVOPLUS Bellows Couplings An innovative modular type coupling perfect in all servo motor applications where high torsional rigidity, backlash free torque transmission, low inertia, and superior reliability are required. Wear and maintenance free. Working temperature up to 300°C. ® SERVOMATE Disc Couplings Specially designed for servomotor applications. The aluminum hubs and the compact design provide low mass moment of inertia resulting in a reliable and maintenance free coupling for high speeds. The double disk pack execution has been designed for applications where radial misalignment exists. * Summary Mechanical Power Transmission Couplings ALL IMAGES ARE LINKS

Pump shaft alignment is key to preventing unnecessary wear and damage to the pump shaft seal and bearing. Improper alignment may lead to premature pump failure. Also to be considered are unwanted torsional resonant frequencies in the system which can quickly cause damage to components in the drivetrain and reduce system life and performance. Improper pump installation can lead to premature failure, increased maintenance costs and reduced production levels of final product. jbj Techniques can advise on the correct installation of into Industrial / hydraulic pumps mobile / marine / machine tool / agricultural / offshore industries and can specify complete driveline systems from their extensive range of components which are available from stock or manufactured to order, albeit simple or complex, standard or bespoke.

Generally manufactured in Cast or Nodular iron, bellhousings can be produced in steel, stainless steel or alternative exotic materials on customer request. Couplings supplied for these applications are the jbj Techniques 'JXL' pin and bush range which provide an anti-static and flameproof drive which meet zone 1 area requirements, conforming to all of the above standards. Also available are spider and gear couplings which are certified to zone 2 standards. (Contact jbj Techniques for details). 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. Diesel Engine – Hydraulic Pump Adaptors A complete range of bellhousing and couplings exist for the connection of a diesel engine flywheel to a specified driven component, be it an oil hydraulic pump, water pump, generator or similar device.
