Dispositivo tribológico para cilindros neumáticos


Oferta Tecnológica
Un instituto de investigación rumano ha desarrollado un dispositivo tribológico para analizar cilindros neumáticos en condiciones de laboratorio que resalta la influencia de la lubricación y presión en las fuerzas de fricción. El dispositivo permite medir de forma comparada y grabar la variación de las fuerzas de fricción. Aunque el dispositivo se encuentra en fase de diseño, resalta la evolución de las fuerzas de fricción en el tiempo, después de varias horas de resistencia. Se buscan socios industriales, académicos e investigadores con el fin de desarrollar el producto y establecer acuerdos de transferencia de tecnología.


Tribological device for pneumatic cylinders
A Romanian research institute has developed a device used to test pneumatic cylinders in lab conditions, which can highlight the influence of the lubrication and working pressure on the frictional forces. Although only in the concept stage, it will highlight the evolution of the frictional forces over time, after several hours of endurance.
Partners in the field of research, academia and industry are sought for, in order to develop the product and for its technological transfer.
The tribological device developed by the Romanian research institute consists of two separate circuits, out of which one is running on ungreased air and the other on greased air, each controlled by a force transducer and by the same single pressure valve associated with a pressure sensor. The device can comparatively measure and record the variation of the occurring frictional forces.
The elaborated device has a pneumatic cylinder, in which there is located a piston provided with rods arranged bilaterally, powered by a pressurized control distributor. In connection with the rods, there have been installed a number of force transducers and sleeves which, at their turn, make the connections with the rods of some pistons arranged in two identical pneumatic cylinders. The first pneumatic cylinder represents the ungreased pressurized pneumatic circuit, together with some check valves, while the second one is the greased pressurized pneumatic circuit that uses some check valves and a "micro mist" lubricator. Both circuits are discharged by the same discharge valve at a pressure that is read by a pressure sensor, in order to measure internal frictional forces, in case of a dry friction compared to greased friction, at the same effective force developed.
The Romanian research institute is looking for EU partners (universities, institutes or SMEs), for research or technical cooperation agreements.
Advantages and Innovations:
- the device directly measures the forces required for movement;
- it highlights the influence of work pressure on the frictional forces;
- the comparative recording of the frictional forces graphs is carried out very accurately, both for ungreased and greased air, as the effective force or the load is achieved in the same conditions;
- it can highlight the evolution of the frictional forces over time, after several hours of endurance.
Stage of Development:
