Abstract

Bomba de engranajes con dos rotores (3), en la que el árbol (1) de un rotor está apoyado en forma deslizante por lo menos en uno de sus lados, caracterizada porque el casquillo (9) del cojinete de deslizamiento del lado de la carcasa se extiende axialmente en una sola pieza hasta salir al espacio exterior (U) que rodea a la bomba, y porque está previsto en el casquillo (9) del cojinete un sistema de conducciones (17) para el medio de regulación de la temperatura, con por lo menos un par de entradas y salidas realizadas en el casquillo del cojinete de deslizamiento, que están situadas en posición abierta en el espacio exterior (U) fuera de la bomba.
