4 #DriveLineHarmony www.jbj.co.uk/couplings.html Pump Drive Components ® Introduction to the Spidex Coupling Spidex couplings are torsional flexible shaft couplings, the operating characteristics of which are two hubs with concave claws, transmitting the torque by meshing with an elastic involute gear ring. The coupling concept gives a reliable, smooth power transmission without torsional oscillation and thus protects the connected machines. Due to the complete flexibility and ductility of the elastomer ring, it compensates for parallel and angular displacements as well as to absorb longitudinal movements of the shafts. The involute teeth of the elastomer element are crowned in order to avoid edge pressure on the tooth flanks and thus avoid undesirable axial thrust. The puncture proof coupling can be loaded extremely high since the elastic elements are submitted to compression and not to bending moments of force. The elastomer gear ring, made of a newly developed Simirit-Polyurethane of various degrees of shore hardness, has important advantages in comparison with the standard polyurethanes. It is non-ageing, with resistance against hydrolysis (can be used in tropical conditions), non-abrasive, has a high self-damping effect and is also resistant to oil 0 0 and ozone. It can be used with temperatures ranging from -40 C to +100 C. Spidex couplings can be used for horizontal as well as for vertical shaft connections, for reversing, intermittent service and are electrically insulating. The operating characteristics and the durability of the coupling are very positively influenced by the high overall precision of the machining, especially the claws, unbalance is reduced to a minimum, running is improved and service life considerably increased. Total service factor for K = K1 x K2 x K3 Displacement values Valid for 1500rpm and for a given temperature range -25°C to +30°C.

Pump Drive Components Introduction to the Spidex® NBL Coupling The NBL series curved jaw coupling offers zero backlash capability in a 3-piece design. The coupling is provided assembled under preload. The NBL series can be used in a variety of different applications requiring precision and accuracy. The NBL series spider features a straight centre of the spider tooth, providing higher stiffness due to coupling preload. The crowning of the ends of the spider legs allows for misalignment, while the curved jaws and solid spider centre provide high-speed capability. The jaws of the hubs and the spider legs are chamfered to provide easy assembley. The NBL coupling design also allows the blind assembly in tight spaces. Raised spider dots on the legs of the spider ensure proper spacing of the hubs and spider. Proper installation of the coupling can provide isolation of electrical currents. Check the 's' dimension listed on page 24 to ensure the proper spacing between spiders between spiders and hubs. The NBL coupling has spiders available in four different shore hardnesses. Each spider offers benefits for different vibratory, environmental and torque transmission requirements. Elastomer Performance Data for NBL Series Coupling Selection for the NBL Series Typical Applications Measurement and Control Systems The torsional stiffness of the NBL series coupling provides the needed accuracy for measurement and control systems. The low torques of these applications gives the NBL series the ability to provide zero backlash due to the elastomer preload. Servo and Positioning Drives The NBL coupling provides a zero backlash, flexible connection for servo and positioning drives. An added benefit of the NBL series is its damping capabilities. For applications that have vibrations at critical speeds, the NBL coupling can provide a zero backlash solution for vibration problems. 22 #DriveLineHarmony www.jbj.co.uk/couplings.html
Main Spindle Drives The NBL coupling is used in main spindle drives for machine tools. Torque spikes and cyclical loading are handled by the NBL series by damping or by shifting the vibratory frequency range to a non-critical speed range.

Pump Drive Components Spidex® NBL Coupling NBL NBL NBL The NBL coupling features different hub designs for different applications. Each type offers specific benefits for different types of application. The clamping styles offer the benefit of minimal to zero backlash. 24 #DriveLineHarmony www.jbj.co.uk/couplings.html
Pump Drive Components Spidex® NBL Coupling Misalignment The NBL coupling handles the axial, angular and radial misalignment whilst retaining it's zero backlash properties due to its spider design. Axial misalignmen ct an be caused by different shaft tolerances or by thermal expansion of shafts. The NBL series coupling handles axial misalignment while keeping reactionary forces low. Radial misalignmen ctan be defined as a measure of the offset distance between the centrelines of the driving and driven shafts. This type of misalignment causes the highest stress due to the forces involved. Angular misalignmen ctan be defined as a measure of the angle between the centre lines of the driving and driven shafts, where those centre lines would intersect approximately halfway between shaft ends. The NBL coupling can handle a specific amount of angular misalignment for each given size. Refer to table on next page. 25 #DriveLineHarmony www.jbj.co.uk/couplings.html
® The Dentex coupling is a flexible gear coupling whose typical features are two congruent hubs with crowned teeth which transmit torque by meshing with the internal toothing of a housing component. The coupling sleeve with axially parallel involute gearing is centred at the tooth flanks of the coupling hubs. The coupling design meets the requirement to compensate radial, angular, and axial shaft displacements in order to release the neighbouring shaft bearings from non-controlled additional bearing loads. Even with the maximum permissible displacement edge contact of the teeth is excluded and there will be no periodic variation of the angular velocity. The high internal cushioning properties of the plastic material used for the coupling sleeve reduce the effect of shock loading. ® Dentex couplings are as suitable for horizontal shaft connection as they are for vertical connection, for reversing and intermittent service, and they have electrical insulating properties, a low weight, a low flywheel effect and, owing to their compactness, only little space is required for them. The steel/plastic combination also has the advantage that no lubrication by oil or grease is required; the coupling therefore does not need any maintenance. The 6,6-polyamide used for the coupling sleeve excells due to its excellent sliding and wear resistance properties especially with the combination of toughness, hardness and rigidity; it is also resistant to condensation and splash water, engine fuels, oils, greases, alcohols, esters, ketones, aliphatic and aromatic hydrocarbons and many other agents. However, substances of strongly polar character such as concentrated mineral acids, formic acid, cresol, glycol, benzyl alcohol can dissolve 6,6-polyamide at high temperature. Maximum service reliability is guaranteed at temperatures in the range from -25°C to +80°C. It is necessary to use a coupling sleeve in heat stabilised polyamide for temperature up to 140°C.

® DENTEX FL couplings are torsionally stiff crowned tooth flange couplings made from a combination of steel and plastic for diesel engine drives. The driving flange is made from glass-fibre reinforced polyamide for high mechanical rigidity and heat resistance. The coupling hub with external crowned teeth is made from steel. ® The Dentex FL coupling allows a keyed connection between diesel engine and hydraulic pump, the pump centred over the SAE housing. ® The application of the Dentex FL coupling results in a non-critical service due to the coupling stiffness. The hazard of a rotating oscillation during the drive will be avoided. If it is not possible to secure the hub by means of end-disc and screw in the case of pump shafts with profiled gear teeth (according to DIN 5480, 5482, SAE), the use of a clamping hub connection should be considered. The radial distortion guarantees a fit on the pump shaft which is free from clearance.

The influencing of airborne, structure borne and liquid sound is incumbent on the pump design engineer himself. The noise characteristics of a pump – consisting of basic frequency and harmonic waves – can become very annoying when the structure borne noise of the hydraulic unit and the integrated elements of the machine are combined. The flow vibration of a pump combined with it’s pressure vibration, can cause a particularly unpleasant resonance of the structure, which in itself cannot always be calculated, even by means of a sound pressure level monitoring in form of a dB(a) value. In order to prevent the reproduction of this vibration into other integrated elements of the structure, it is necessary to isolate the structure borne noise. This is achieved by the use of flexible drive couplings, flexible connections on pipe work and also by the use of bellhousings with integrated noise / vibration reduction flanges. Damping flanges of this type consist of an elastomeric element, which isolates the metallic contact between the pump and other elements of the hydraulic unit. Our associate company, Raja-Lovejoy manufactures and distributes damping flanges for the reduction of noise within hydraulic units. With many years of experience within this field, a monobloc bellhousing system with integrated noise damping has been developed, (top left drawing, page 39), which offers a simples solution against conventional solutions. The connection between the noise damping ring and the bellhousing is of moulded design using a form conclusive and vulcanised elastomer compound and is designed to avoid rotation and radial wind up. The design provides a noticeable improvement in stiffness, resulting in a tensile strength of 56 kN, (based upon a monoblock bellhousing with a motor flange diameter of 300mm and is suitable for use with an electric motor with frame size D132). The higher stiffness results in reduced shaft misalignment and increases the service life of the drive coupling. The noise damping effect of the monobloc bellhousing is effected by the installation as well as the noise characteristics of the pump. The more annoying the pumps noise the higher the damping degree will be. The spectrum of sound level reduction generally lies between 3 dB(a) in the case of less noisy pumps (Fig. 1) and more than 10 dB(a) by pumps (Fig. 2), which produce higher levels of noise.

BACKLASH Backlash is the clearance or gap between the trailing or non-driving surfaces of the coupling jaws and flexible element, illustrated in red on the above diagram. When used in reversing or heavy cyclic applications where the coupling is required to rotate in both directions the application must be considered with the type of use, number of starts per hour considered and an appropriate service factor applied to prevent premature failure of the coupling element. Standard spider 'teeth' are curved in two directions. NON-BACKLASH The coupling element and claw profile are designed such that the element is compressed when the coupling is assembled in order to remove backlash, typical applications are for indexing or positioning drives such as lead screws or encoders where a high degree of accuracy is required. The pre-compression or preload of the element whilst providing greater accuracy also increases the dynamic torsional stiffness from 25% to 75% over the standard element at 50% of it's nominal torque rating, (depending on coupling size), thus maintaining accuracy even after extended periods of use. Nonbacklash spider 'teeth' are curved radially and parallel axially. 55 #DriveLineHarmony www.jbj.co.uk/couplings.html Pump Drive Components Backlash Explained

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. Electric Motor – Hydraulic Pump Adaptors (safe area) jbj Techniques Limited offer the most comprehensive range of in Europe. bellhousings Designed to connect electric motors with frame size IEC D56 - D400 (0.06kW – 750kW) and can be compatible with electric motor 'B5' or 'B14' flange configurations.

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.
