Abstract

Bomba de husillo helicoidal con una carcasa de bomba que rodea un espacio de transporte, en la que están alojados un husillo de accionamiento y al menos un husillo de giro en sentido contrario, cuyos cojinetes están alojados fuera del espacio de transporte en un elemento de cojinete, en el que el elemento de cojinete (15) presenta una primera sección de tapa de cojinete (16) esencialmente anular unida en el espacio de transporte y una segunda sección de tapa de cojinete (17) esencialmente anular con escotaduras (21, 22) para rodamientos y cojinetes de fricción, caracterizada por que la primera y la segunda sección de tapa de cojinete (16, 17) presentan, respectivamente dos superficies de contacto (9, 20) distanciadas entre sí y las secciones de tapa de cojinete (16, 17) están unidas entre sí solamente sobre las superficies de contacto (19, 20) y, por lo demás, presentan una distancia entre sí.Helical spindle pump with a pump housing surrounding a transport space, in which an actuating spindle and at least one counter-rotating spindle are housed, whose bearings are housed outside the transport space in a bearing element , wherein the bearing element (15) has a first essentially annular bearing cover section (16) joined in the transport space and a second essentially annular bearing cover section (17) with recesses (21, 22) for bearings and friction bearings, characterized in that the first and second bearing cover section (16, 17) have, respectively, two contact surfaces (9, 20) spaced apart from each other and the bearing cover sections (16, 17) are joined together only on the contact surfaces (19, 20) and, otherwise, have a distance from each other.
