Las máquinas móviles emplean para su accionamiento mayormente motores de combustión interna. Los acoplamientos hidrostáticos se acoplan entonces directamente con bombas hidráulicas, en compresores móviles la unidad de compresión se acciona directamente. La unión de ambas unidades se realiza mediante un acoplamiento de brida. Este debe cumplir numerosos requisitos; en primera línea sin embargo debe transmitir la fuerza de forma fiable, de manera que con las máquinas de trabajo se puedan ejecutar las tareas tal como deseado.

BoWex® Flange couplings - Behaviour of friction and wear

The smooth and hard surface (crystalline structure) and the high thermal stability and resistance to lubricants, fuels, hydraulic fluids, dissolvents, etc. make polyamide an ideal material for components stressed by sliding, particularly for the coupling production.

BoWex-ELASTIC® HE1/HE2 - General description

For drives subject to dangerous torsional vibrations to transmit the torque flexibly for the combination of diesel engine with splitterbox, generator, compressor, feed pump or high-pressure pump, etc.:

BoWex-ELASTIC® is highly flexible combining the benefits of the well-approved BoWex® system in a compact design with the option of an axial plug-in assembly inside the curved toothing. Torsional vibrations and shock loads are damped and reduced. Also, the coupling allows for compensation of radial, angular and axial inaccuracies in alignment with extremely low restoring forces.

BoWex-ELASTIC® consists of a highly flexible, rubber element made from natural rubber which is governed by the size of the coupling. The internal axial plug-in hub with external spline corresponds to the BoWex® basic design. BoWex-ELASTIC® is available in different kinds of elastomer hardness with engine flywheel connection flanges to SAE J620 and special dimensions for a power up to 1,000 kW.

Pump mounting flanges

Pump mounting flanges

For connecting hydraulic pumps to the diesel engine KTR supplies mounting flanges according to SAE connection dimensions sizes SAE 6 to SAE 1. These flanges are made of steel and EN-GJL--250 (GG25) for hydraulic pumps with flange connections according to SAE-A, -B, -C, -D and -E as types with 2 and 4 holes.

Pump connection housings made of EN-GJL-250 (GG25) to be mounted directly to the back plate of the engine.
