1. A helical gear transmission for an electromechanical servo steering mechanism, the helical gear transmission comprising:
a shaft that meshes with a helical gear, wherein the shaft is disposed in a transmission housing, wherein a first end of the shaft is mounted in a first bearing arrangement so as to be rotatable about an axis of rotation, wherein a second end of the shaft is mounted in a second bearing arrangement in the transmission housing, wherein the first bearing arrangement includes a rolling bearing, an outer ring of which is spherical, wherein the rolling bearing is enclosed by two bearing shells, wherein an outer side of the outer ring of the rolling bearing has two flat points that lie opposite each other in a circumferential direction and form a pivot axis about which the shaft is pivotable in a direction of the helical gear.
