Abstract
Estructura de soporte de cigüeñal Objeto: En una estructura de soporte en la que un cigüeñal se soporta rotativamente por un cárter a dividir por un plano que incluye el eje rotacional del cigüeñal mediante cojinetes dispuestos en posiciones que intercalan un muñón entremedio, el objeto de la presente invención es controlar la cantidad de vibraciones de los cojinetes en la dirección a lo largo del eje del cigüeñal dentro de una banda deseada para mejorar la durabilidad de los cojinetes y evitar variaciones en la transmisión de sus vibraciones y ruidos. Solución: Los anillos de rodadura interiores 86 de los cojinetes 84 se montan en un cigüeñal 31 en posiciones predeterminadas en la dirección a lo largo del eje de un cigüeñal 31 de tal forma que no se puedan mover relativamente con respecto al cigüeñal 31, y los anillos de rodadura exteriores 85 de los cojinetes 84 se montan en un cárter 29 en posiciones predeterminadas en la dirección a lo largo del eje del cigüeñal 31 de tal forma que nose puedan mover relativamente con respecto al cárter 29.Crankshaft support structure Object: In a support structure in which a crankshaft is rotatably supported by a crankcase to be divided by a plane that includes the crankshaft rotational axis by means of bearings arranged in positions that intersperse a stump in between, the object of the The present invention is to control the amount of vibration of the bearings in the direction along the axis of the crankshaft within a desired band to improve the durability of the bearings and avoid variations in the transmission of their vibrations and noise. Solution: The inner raceways 86 of the bearings 84 are mounted on a crankshaft 31 in predetermined positions in the direction along the axis of a crankshaft 31 so that they cannot move relatively with respect to the crankshaft 31, and the outer raceways 85 of the bearings 84 are mounted in a crankcase 29 in predetermined positions in the direction along the axis of the crankshaft 31 so that they cannot move relatively relative to the crankcase 29.
