Pump Drive Components Anti-Vibration/Noise Reduction Mountings for noise reduction of hydraulic power units Damping flanges For use in combination with Raja bellhousings between electric motor and hydraulic pump. They consist of two aluminium parts which are connected by a rubber coat (Nitrile) without any metal connection. They are resistant against mineral oils and suitable for working temperatures up to +80 oC, for short time +100 oC. The possible noise reduction will be approx. 3 - 8 db(A). Damping flanges are available in two degrees of hardness with the description N - normal / H - hard....

Pump Drive Components Anti-Vibration/Noise Reduction Mountings for noise reduction of hydraulic power units Damping rings For use when vertical mounting (VI-construction) between bellhousing and tank lid or horizontal (B5-construction) mounting position between motor and bellhousing flange. They consist of two reinforced aluminium rings which are connected by a rubber coat without any metal connection. The used materials (Nitrile) are resistant against mineral oils and suitable for working temperatures up to +80 oC. The possible noise reduction will be approx. 3 - 5 db(A). Permissible radial...

Introduction to the Spidex® Coupling Pump Drive Components 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...

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...

Pump Drive Components Misalignment The NBL coupling handles the axial, angular and radial misalignment whilst retaining it's zero backlash properties due to its spider design. Axial misalignment can be caused by Radial misalignment can be defined as a Angular misalignment can be defined as a different shaft tolerances or by thermal measure of the offset distance between the measure of the angle between the centre lines expansion of shafts. The NBL series coupling centrelines of the driving and driven shafts. of the driving and driven shafts, where those handles axial misalignment while keeping...

Introduction to the Dentex® Coupling Pump Drive Components 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...

Pump Drive Components Standard Dentex® Coupling B H* is the minimum dimension required for the disengaging of the coupling. Finish bores according to ISO-standard H7, keyway according to DIN 6885, sheet 1 (JS9). Weight and moment of inertia values refer to maximum diameter d without keyway. Assembly Instructions On assembly it is important that the hubs are correctly fitted on the shafts and that the dimension E is maintained. The dimension E can be controlled by the total assembley length L. An incorrect dimension E has a negative influence on the performance of the coupling. Check the coupling...
