Screw-spindle pump, fuel delivery assembly, and fuel delivery unit

A screw-spindle pump (P) comprising:

• a first screw spindle (2) and a second screw spindle (4), wherein the first screw spindle (2) is a drive spindle and the second screw spindle (4) is a running spindle that runs oppositely with respect to the first screw spindle (2);
• and
• a pump housing (6) configured to receive the first and second screw spindles (2, 4),
• wherein the first and second screw spindles (2, 4) form, together with at least the pump housing (6), delivery chambers (10), which move from a suction side (12) of the pump (P) to a pressure side (14) of the pump (P) as a consequence of a rotation of the first and second screw spindles (2, 4),
• wherein the pump housing (6) has a first abutment insert (16) configured as an abutment surface against which the first screw spindle (2) abuts and is thus supported and a second abutment insert (18) configured as an abutment surface against which the second screw spindle (4) abuts and is thus supported, and
• wherein at least one of the first and second abutment inserts (16, 18) is arranged so as to be angled (α1, α2) with respect to a first plane (X-Z) of the pump (P), so as to counteract operationally induced crossing of the first and second screw spindles (2, 4).
