Desearia poder obtener informacion sobre alineamiento de maquinas rotativas llamese grupos electrogenos, bombas de agua , motores en si como se realiza un alinemiento,.. Gracias

Tengo algunos archivos en pdf. que te pueden servir, son de alineamiento de motores diesel marinos, los prinsipios son similares para los otros casos. saludos. Diesel Help. My e-mail es email@example.com
agradesco el interes prestado espero q puedas enviarme estos archivos a mi correo Ftardillo@hotmail.com
Saludos amigo... 2.3.5. The Alignment of Propeller The alignment of the engine and marine transmission with the propeller shafting is essential to minimize vibration, noise, power loss and stress in the driveline components. While aligning the engine and gear, check both the propeller shaft flange bore and face. The shaft and gear flanges should fit together without deflecting either the engine or the shaft from its operating position. This will allow the propeller shaft flange and reduction gear output flange to mate properly without over stressing the driveline components. The shaft should then be rotated 180° and checked again. The propeller shaft flange bore and face alignment should not be done before the vessel is in the water and, on a solid mounted engine, should be rechecked after the vessel has been in the water and loaded to its normal operating condition. Engine, gearbox and propeller shaft must be aligned in such a way that radial and angular offset of all components remain within the pre-set tolerances. (1) Radial offset check The feeler of the dial indicator runs on the peripheral surface of the fixed flange. The shaft end with the dial indicator placed on it must be turned. The reading must not vary by more than 2x0.5 mm=1.0mm. (2) Angular offset check The feeler of the dial indicator runs on the front side of the fixed flange. The shaft end with the dial indicator placed on it is to be turned. The feeler must contact the mating surface. A 360° turn is required for each check. The max. Permissible angular offset must not be exceeded at any measuring point. Chapter 3. Front power-Take-Off 3.2.1. For Maximum FPTO power For front power take-off in engine, install a flexible coupling to the engine front crank shaft pulley and connect drive shaft and V-pulley by supporting them with two pillow blocks as shown in Fig. It is a standard procedure to support driveshaft and V-pulley with two pillow blocks by using flexible coupling for connection to engine. DAEWOO recommends you this type to use front power take-off. (FPTO). When the front PTO is installed, be sure to take deflection reading. Radial run-out should be no more than 0.02 mm.
