Abstract: A helical gear transmission for an electromechanical servo steering mechanism may include a shaft that meshes with a helical gear. The shaft may be arranged in a transmission housing and, at its first end, may be mounted in a drive-side bearing arrangement so as to be rotatable about an axis of rotation. At its second end, the shaft may be mounted in a drive-remote bearing arrangement in the transmission housing. The drive-side bearing arrangement may have a rolling bearing, an outer ring of which is spherical. The rolling bearing may be enclosed by two bearing shells. The outer side of the outer ring may have two flat points that are opposite one another and form a pivot axis about which the shaft is pivotable in a direction of the helical gear.

Abstract: The body mass of the test body is optically determined in the holding station (1). Oblong test bodies are placed in grooves (13) and cylindrical test bodies in V-shaped slots (14). It is therefore possible to prepare optimally for the optical measurement of the thickness by knowing the geometry of the test body, and for the hardness measurement by presetting the jaws (62, 63) so that the individual steps can be carried out more rapidly in succession. A larger number of test bodies can therefore be tested in a shorter time.
