Abstract
A helical-gear transmission for an electromechanical power steering includes a shaft intermeshing with a helical gear. The shaft is arranged in a transmission housing and is rotatably mounted in the transmission housing about a longitudinal axis, having the first end thereof in a drive-side bearing arrangement and the second end thereof in a non-drive-side bearing arrangement. The transmission housing has, in extension of the shaft on a non-drive-side end, an opening which can be sealed by a cover, wherein the cover has a cover base and a surrounding cover edge, wherein the cover base has, in the region of the shaft, a bulge extending to the outside in the direction of the shaft which forms an axial lock of the shaft.
